Digital Media

Digital film for Digital Cameras
Just like 35mm cameras need traditional "roll film", today's digital cameras need "digital film", also referred to as "digital media", to capture and store pictures. Lexar Media designs digital film that brings out the ultimate performance from any digital camera. Digital media is available in five formats including CompactFlash, SmartMedia, Memory Stick, MultiMedia Cards, and SD cards.

USB-Enabled Compact Flash

Card Care Tips              

     Card Care tips to  prevent the loss of your digital pictures.

  1.Always reformat the card in your camera each time after downloading and saving the pictures on your computer. Don't use the computer to format the card.

  2.Always create a backup by saving your files from the memory card to your computer. You might also create a second backup on a CD.

  3.Try not to let the memory card get too full before downloading the pictures to your camera. Cards that get too full have been known to write over the card headers.

  4.Always charge your batteries sufficiently before taking pictures. Keep a set of fully charged spare batteries handy just in case.

  5.Do not remove the card from the camera too quickly while the camera is still saving data to it. Wait a few moments until you're sure the picture is completely written to the card.

  6.Wait a few seconds before shutting off the camera for the picture to be written to the memory card. With the power shut off the camera may stop writing to the card causing a file corruption.

  7.Do not take pictures too close together beyond the manufacturer's recommended interval. The camera will not be able to finish writing one picture completely before starting on the next.

  8.Avoid large static charges, and be extra careful when handling cards in dry low humidity areas.

  9.Keep cards away from strong magnetic sources, and extreme heat and cold. Walk-thru airport x-rays and scanners are safe, but avoid the stronger x-ray equipment used to examine checked baggage.

  10.Don't remove the card from a card reader too quickly. Wait until it has finished communicating with the hard drive and all files on that card are closed.

  11.Edit and delete pictures on the memory card with your computer, not with the camera. Too many file edits and picture deletes in the camera have been known to cause card problems.

  TOP  

  12.If a memory card problem occurs, stop using the card immediately. Do not reformat the card or delete pictures. Use an Image Recovery program or send the card to an Image Recovery Lab to retrieve the files.

  13.Be careful with the Delete All and Card Format options in the camera. Depending on the camera, these operations are sometimes irreversible. Don't let people unfamiliar with the camera navigate the menus.

  14.If you own more than one digital camera, keep the cards for each camera separate. Do not take pictures on one card and then put the card in the other camera and start taking more pictures. This will likely corrupt the card. If you must switch out cards between cameras, format the card in the new camera first before doing anything.

Glossary of Basic Photo Terms

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

A
AMBIENT LIGHT: The light in the scene, as opposed to the light provided by the photographer with flash, photofloods, etc.

ANGLE OF VIEW: The maximum angle a lens covers in the field. Measured in degrees, and qualified by terms such as wide-angle, normal, and telephoto. A wide angle lens has a wider angle of view than a telephoto lens. A 135mm lens on a 35mm SLR covers an 18-degree angle of view; a 28mm lens covers a 75-degree angle of view.

APERTURE: The opening of a lens, the size of which is controlled by a diaphragm. The term is commonly used to designate f-stops, such as f/4, f/5.6 etc., which are actually arrived at by dividing the focal length of the lens by the diameter of the aperture. Thus, f/11 on a 110mm focal length lens means the opening is 10mm. The wider the opening, the lower the f-number, the more light is let through the lens. Each step in aperture represents a halving or doubling of light. Thus, f/8 allows in half as much light as f/5.6, and twice as much light as f/11.

APERTURE PRIORITY: An autoexposure mode in which the aperture is selected and the exposure system selects the appropriate shutter speed for a correct exposure. Sometimes referred to as AV or simply A on exposure mode controls.

ARCHIVAL: Long-lasting. In processing, those procedures that help insure stability of the image. Also, storage materials that will not damage photographic film and paper, or computer-produced prints.

ARTIFICIAL LIGHT: Any light not directly produced by the sun. Can be tungsten, flash, household bulbs, sodium vapor street lamps, etc. In many cases, the color produced by artificial light is deficient in the blue end of the spectrum, thus daylight-balanced color films will record the light as being warm/red/amber. Tungsten-balanced slide films, or color-balancing filters over the lens will generally correct this problem. In some cases, color print film can be re-balanced when prints are made.

 TOP 

AUTOEXPOSURE: A method of exposure where aperture and shutter speed settings are first read, then set, by the camera's exposure system. Various autoexposure modes allow for customization or biasing the readings.

AUTOEXPOSURE LOCK: A push-button, switch, or lever that locks in exposure after the initial reading has been made, regardless of a change in camera position or light conditions after the lock is activated. Release of the lock button returns the exposure system to normal. Useful for making highlight or shadow readings of select portions of the frame, and an essential feature for critical exposure control with automated cameras.

AUTOFOCUS: A method of focusing where focusing distances are set automatically. In 35mm SLRs, a passive phase detection system that compares contrast and edge of subjects within the confines of the autofocus brackets in the viewfinder and automatically sets focusing distance on the lens. Autofocusing motors may be in the camera body or the lens itself. Active IR (infrared) autofocusing systems may also be in 35mm SLRs in the form of beams in dedicated autofocus flash units, or, in a few models, built into the camera itself. Commonly found in amateur lens/shutter cameras. These beams are emitted from the camera or flash, bounce off the subject, then return and set focusing range.

AUXILIARY LENS: An add-on optical device that alters the focal length of the prime lens for close-up, telephoto, or other special effects photography. The close-up devices, for example, usually comes in +1, +2, and +3 powers; the higher the number the greater the magnification.

AVAILABLE LIGHT: The light that's normal in a scene, although the term is generally used when the light level is low. Available light shooting usually involves fast film, low shutter speeds and apertures, and/or the use of a tripod.

AVERAGING: In light metering, where the light is read from most of the viewfinder frame then averaged to yield an overall, standard exposure for the scene. This setup works fine in normal lighting conditions, but may need some additional input when light is flat or contrasty.

 TOP
 
B
B or BULB: A shutter setting that indicates that the shutter will remain open for as long as the shutter release is pressed. The term originated with the rubber air shutter bulbs used to operate shutters in the old days. B settings are generally used in nighttime and time/motion study photography.

BACKGROUND: The portion of a scene that sits behind the main, foreground subject. The background can be made sharp or unsharp through the use of selective focusing techniques and depth of field manipulation.

BACKLIGHTING: From camera position, light that comes from behind the subject. Usually, a backlit main subject will be underexposed unless the metering system is set to read selectively off the subject, or exposure on a center-weighted meter is compensated accordingly. See also fill-flash. Extreme backlighting can be exploited to create silhouettes.

BLACK-AND-WHITE: A photographic film or paper used to create monochrome images. Though we think of black and white mainly in terms of a gray scale, prints can have a wide variety of subtle tones, from blue- to brown-black. Though the overwhelming majority of photography today is shot and printed in color, black-and-white has attracted a fiercely loyal and dedicated group of photographers.

BLUR: Unsharpness because of the movement of the camera or subject during exposure. Blur can be used for many creative effects. In computer imaging, the use of Blur controls to selectively soften parts of the image.

BOUNCE LIGHT: In flash photography, directing the burst of light from the flash so it literally bounces off a ceiling, wall, or other surface before it illuminates the subject. This method of flash is often preferred because it softens the overall light and eliminates the harsh, frontal effect of an on-camera, straightforward flash.

 TOP 

BRACKET: Making exposures above and below the "normal" exposure, or overriding the exposure suggested by the camera's autoexposure system. Useful as a fail-safe method for getting "correct" exposure in difficult lighting conditions. Bracketing can also be used to make subtle changes in the nuance of tone and light in any scene. With slide film, bracketing will show an effect in 1/3 stop increments; with negative film a full stop of bracketing is advised.

BRIGHTNESS: The luminance of objects. The brightness of any area of the subject is dependent on how much light falls on it and how reflective it is. Brightness range is the relationship we perceive between the light and dark subjects in a scene. Brightness contrast is a judgment of the relative measure of that range, such as high, low, or normal. Brightness values are sometimes referred to as EV (exposure values), a combination of aperture and shutter speed. Brightness values in the scene are translated to tonal values on film.

BURNING-IN: In darkroom work, giving additional exposure to a portion of a print made from a negative to add density and tonal information. Often used to balance tones in contrasty scenes. The same term is used in digital darkroom programs.

BURNT-OUT: Jargon that refers to loss of details in the highlight portion of a scene due to overexposure. With slide film, it might mean that no image detail has been recorded on the film, or that highlights show no texture or tonal information. A highly burnt-out, or burnt-up slide may show clear film base in overexposed areas.

C
C-41: The current process for all standard color negative films.

CABLE RELEASE: A flexible encased wire attached to a threaded metal coupler that screws into the shutter release button on the camera. When one end of the wire is depressed with a plunger the other end activates the shutter. Electronic cable releases for all-electronic cameras work with electrical impulses rather than mechanical plungers. Usually, the two types are incompatible. Useful for long exposures to avoid camera shake and for remote release of the shutter.

 TOP 

CAMERA: A light-tight box containing light sensitive film or sensor that is used to make images. Today's cameras incorporate microprocessors and sophisticated exposure systems; in a sense, the instrument itself mirrors the age, just as the pictures it makes reflect the world in which we live.

CCD: For charged couple device; the sensor used by most digital cameras, and in flatbed scanners.

CD-ROM: A compact disc that can store a large amount of information. The CD-ROM drive reads that information. CD-R is a recordable CD for home and studio use. The Photo CD and CD-R are write once, read many times discs; a CD-RW is a CD that can be written over, if desired.

CENTER-WEIGHTED: In a metering scheme, an exposure system that takes most of its information from the center portion of the frame. Most center-weighted systems also take additional readings from the surround, but weight the reading towards the center.

CHIP: Common name for sensor, actually a silicon wafer with circuit paths etched or printed in layers.

CLOSE DOWN: Jargon that refers to making a photograph with less exposure than previously used. With apertures, using a narrower apertures; with shutter speed, using a faster shutter speed. For example, going from f/8 to f/11 means closing down the lens by one stop.

CLOSE-UP: Any photograph made from a distance that is generally closer than our normal viewing distance. Close-up pictures are often startling in the detail they reveal.

COLOR BALANCE: The color balance of a film refers to the kind of light under which it will faithfully render color without the need for filters. Most films are daylight-balanced, which means that in daylight, or with a daylight balanced flash, colors will be true. A tungsten-balanced film can be used under certain types of artificial light to give true colors without filters or special printing techniques.

  TOP 

COLOR COUPLER: A colorless substance contained in color film emulsions that, when exposed to chemical developing baths forms the color dyes that make up part of the layers of processed color films.

COLOR NEGATIVE FILM: A film that forms a photographic image in which light tones are rendered dark (and vice versa) and colors are reproduced as their complements (such as blue being recorded as yellow); all of reversed tones and colors are then reversed again in printing to form a positive record. Color negatives have an orange mask (an aid to printing), so may be difficult to "read". Color negative films come in a range of speeds (ISO), or sensitivities to light. Each speed of film has its uses and characteristics that can be matched to particular shooting needs.

COLOR TEMPERATURE: The Kelvin scale, which is defined in degrees. It is used as a standard for balancing daylight films (approximately 5500 degrees K) and tungsten-balanced film (approximately 3200 degrees K.) Color conditions that vary from the standards will create a color cast in photographs made with these films, e.g., a daylight film used with artificial light will record with an amber cast; a tungsten film used outdoors will record with a blue cast.

COMPOSITION: The arrangement of subject matter, graphic elements, tones, and light in a scene. Can be harmonious or discordant, depending on the photographer, his or her mood, and the subject at hand. There are no set rules, just suggestions; successful compositions are ones that best express particular feelings about the subject or scene.

CONTACT PRINT: A print made the same size as the negative.

CONTRAST: The relationship between the lightest and darkest areas in a scene and/or photograph. A small difference means low contrast; a great difference high contrast. High contrast scenes usually cause the most exposure problems; however, their difficulty can mean they hold the potential for more expression. Though contrast is often linked with scene brightness, there can be low contrast in a bright scene and high contrast in dim light. Contrast can also describe attributes of color, composition, and inherent qualities of film.

CONTRAST GRADE: In black and white printing, an indication of the contrast rendition the paper will yield. #0 and #1 are low contrast; #4 and #5 are high contrast. The "normal" contrast grade is #2.

  TOP 

CONVERSION FILTER: A filter that gives allows daylight film to record color faithfully in artificial light or, conversely, for tungsten-balanced film in daylight. For example, orange conversion filters are used when exposing tungsten-balanced films in daylight, bluish filters for daylight-balanced films in tungsten light. Most useful with slide films, as color negative imbalances can usually be corrected when prints are made.

CORRECT EXPOSURE: The combination of aperture and shutter speed that yields a full-toned negative or slide that yields the best possible tonal representation of the scene onto film or sensor. The constants in an exposure calculation are the speed of the film and the brightness of the scene; the variables are the aperture and shutter speed.

CROP: To select a portion of the full-frame image as the final picture. Cropping is done in the darkroom or computer environment by the photographer, or by an appointed surrogate in a commercial photo lab.


D
DAYLIGHT-BALANCED: A film that will reproduce colors faithfully when exposed in daylight. The film can also be used with flash, as properly made flash or strobes yield daylight-balanced light.

DARKROOM: The work space for developing and printing photographic film and making prints.

DEDICATED FLASH: A flash that coordinates with the camera's exposure, and sometimes focusing systems. Dedicated flashes may, among other things, automatically pick up the loaded film's ISO, set the camera shutter speed to X-sync, and "tell" the camera when its ready to fire. Flashes dedicated to autofocusing cameras may also vary their angle of flash throw according to the lens in use (even with zoom lenses), and contain autofocus beams that aid focusing in very dim light or even total darkness. For outdoor work, dedicated flashes may provide totally automatic fill-flash exposure. In short, a dedicated flash can be make flash photography as simple as automated natural light photography.

TOP 

DENSITY: In general terms, the measure of the light-gathering power of silver or dye deposits in film. Also, the buildup of silver that creates the image in film and paper. A "dense" negative or slide is more opaque than a "thin" one. There is an ideal density for film, one that yields good prints or slides; too little density usually means that the film was underexposed (or underdeveloped), too much means its been overexposed (or overdeveloped).

DEPTH OF FIELD: The zone, or range of distances within a scene that will record on film as sharp. Depth of field is influenced by the focal length of the lens in use, the f-number setting on the lens, and the distance from the camera to the subject. It can be shallow or deep, and can be totally controlled by the photographer. It is one of the most creative and profound effects available to photographers.

DEPTH OF FIELD PREVIEW BUTTON: A switch, button, or electronic push-button that allows for preview of the depth of field of the set aperture in the viewfinder. During composition the lens is wide open, thus the depth of field in the viewfinder is always that of the maximum aperture of the lens. It is very useful for critical selective focus shots; although some rightfully consider it no more than an approximation, others feel that an SLR lacking a depth of field preview function is greatly diminished as a creative tool.

DEVELOPING: A series of chemical and physical actions done in a commercial lab or the home darkroom that converts light-struck film to an image that can be viewed directly or printed; making prints from negatives.

DIGITAL: Information used by the computer, represented by numbers. The buzzword for any capture device that converts photons to electrons. The use of that information to store, manipulate, transmit or output images in a computer environment. As opposed to analog.

DIGITAL CAMERA: A filmless camera that converts light energy to digital information and stores that information in a buffer or directly onto a removable memory card.

DIGITAL DARKROOM: The computer and image editing and manipulation programs.

DIGITIZE: The conversion of analog (film, print) information to digital form by use of a scanner, digital sensor or camera.

DISTORTION: Any changing of line, form, or even light by photographic materials, such as lenses, films, or filters. Though most designers do all they can to eliminate distortion from lenses, most photographers take the "if you can't beat 'em, join 'em" approach and exploit it wherever they find it; they use distortion as part of their visual expression.

DODGING: In conventional or digital printing and image manipulation, the selective reduction of density in certain areas of the scene.

DX-CODING: A system of film cassette coding and in-camera pins that informs the camera's exposure system that a specific speed and exposure length film is loaded. Most modern 35mm cameras have this feature.

TOP 

E
E-6: The current developing process for the majority of today's color slide films; the term also refers to films developed by this process, such as E-6 type films.

ELECTRONIC FLASH: Known as a flash gun, strobe, or speedlight, it consists of a gas-filled tube that is fired by an electrical charge. It can be mounted directly on the camera hot shoe (which links the shutter firing to the flash firing), or on a bracket or stand and be connected to the camera via a sync cord.

EMULSION: Used alternately with film, but refers to the coating on the acetate film base. Emulsions consist of light-sensitive silver salts, color couplers, filters, and other layers that work together to both protect and form the actual photographic image on film.

ENLARGEMENT: Making a print from a negative or slide; generally, making a print larger than standard size, such as an 8x10-inch or bigger "blowup".

EXPOSURE: The amount of light that enters the lens and strikes the film or sensor. Exposures are broken down into aperture, which is the diameter of the opening of the lens, and shutter speed, which is the amount of time the light strikes the film. Thus, exposure is a combination of the intensity and duration of light.

EXPOSURE LATITUDE: The range of exposures in which a satisfactory image will be produced on a particular type of film or sensor.

EXPOSURE METERS: Light reading instruments that yield signals that are translated to f-stops and shutter speeds. Reflected-light meters read light reflected off the subject; incident meters reads light falling upon the subject. All in-camera meters are of the reflected-light type.

F-NUMBERS: A series of numbers designating the apertures, or openings at which a lens is set. The higher the number, the narrower the aperture. For example, f/16 is narrower (by one stop) than f/11--it lets in half as much light. An f-number range might be f/2.8, f/4, f/5.6, f/8, f/11...To find the next aperture in a narrowing series, multiply by 1.4. F-numbers are arrived at by dividing the diameter of the opening into the focal length of the lens, thus a 10mm diameter opening on a 110mm lens is f/11. Alternately used with f-stops.

  TOP 

F
FAST: A term used to describe a film with a relatively high light sensitivity, a lens with a relatively wide maximum aperture, or a shutter speed, such as 1/1000 second, that will freeze quick action.

FILL-IN FLASH: Flash used outdoors, generally to balance a subject that is backlit. Can also be used to control excessive contrast, add light to shadows, or brighten colors on an overcast day.

FILTERS: Any transparent accessory added to the light path that alters the character of the passing light. With film, filters can alter contrast, color rendition, or the character of the light itself (diffusion, diffraction, etc.) In printing, variable contrast filters are used to evoke different contrast grades from variable contrast black and white paper. In computer imaging software, a set of instructions that shape or alter the image information.

FILM: A compilation of light sensitive silver salts, color couplers (in color film), and other materials suspended in an emulsion and coated on an acetate base. The storehouse of our visions, nightmares, and dreams.

FINE GRAIN: Usually found in slow speed films, a fine-grained image is one where the medium of light capture and storage, the silver halide grain, is virtually invisible in the print or slide. With high, or coarse grain films (usually very high speed films) the texture of the grain becomes part of the physical reality, or weave of the image.

FIXER: The third step in black and white print and film processing; the bath removes unexposed silver halides.

FLARE: In lenses, internal reflections and/or stray light that can cause fogging or light streak marks on film. In general, zoom lenses have more potential for flare than fixed-focal-length lenses; in either case a screw-on lens hood helps reduce the problem.

FLAT: Low in contrast, usually caused by underexposure or underdevelopment of film. Flat light shows no change in brightness value throughout the entire scene.

FOCAL LENGTH: The distance from the lens to the film plane or sensor that focuses light at infinity. The length, expressed in millimeters, is more useful as an indication of the angle of view of a particular lens. A shorter focal length lens, such as a 28mm, offers a wider angle of view than a longer one, such as 100mm.

FOCUS: Causing light to form a point, or sharp image on the image sensor or film.

FOCUS LOCK: In autofocus camera systems, a button, lever, or push-button control that locks focus at a particular distance setting, often used when the main subject is off to the side of the frame or not covered by the autofocus brackets in the viewfinder.

FORMAT: The size of the film, thus the camera that uses such film. Large format refers to 4x5 inches and larger; medium format uses 120 or 220 (6cm wide) film. Smaller formats include 35mm and 24mm. In computer imaging, the file structure, or "language" that can be understood by the device.

FRAME: The outer borders of a picture, or its ratio of the height to width. The individual image on a roll of film. Also, to compose a picture.

TOP 

G
GRAIN: The appearance or echoes of the silver crystals in film in the final negative or positive image. The larger the area of the grain in the film emulsion, the more sensitive the film is to light; the more sensitive it is to light the "faster" it is. Larger grains are manifest in the image as mottled or salt-and-pepper clumps of light and dark tones, usually apparent in very fast films on visual inspection, in slow films upon extreme magnification. Grain is most easily seen as non-uniform density in areas sharing the same tone (such as a gray sky.)

GRAY SCALE: The range of tones, from bright white to pitch black that can be reproduced in a film and print.

GROUND GLASS: A specially prepared glass used as the focusing screen in cameras.

GUIDE NUMBER: A number that relates the output of electronic flash when used with a particular speed film. The higher the guide number, the more the light output. Guide numbers, or GN serve as a way to calculate aperture when shooting flash in manual exposure mode. Dividing distance into guide number gives the aperture: For example, a flash with a guide number of 56 (with ISO 100 film) would give a correct exposure at 10 feet with an aperture of f/5.6. With the state of today's automatic exposure flashes, guide numbers today are mostly useful for comparing the relative power of one flash to another.

H
HIGH CONTRAST: A scene where the range between the brightest and darkest areas is extreme, or is such that it may cause exposure problems. A film that renders scenes in high-contrast fashion. The absence of middle grays.

HIGHLIGHTS: The brightest parts of a scene that yield texture or image information. With slide film, it's best to bias expose for the highlights, as overexposure of bright areas will yield a burnt-out look. A spectral highlight is pure light and will print as "paper" white.

HOT SHOE: The mount on the camera body in which electronic flashes are secured. Hot shoes usually contain electrical contact points that signal the flash to discharge when the shutter is fired.

HYPERFOCAL DISTANCE: The nearest point in the scene which is in focus when the lens is focused at infinity. This distance changes according to the focal length of the lens and the aperture at which it is set. Setting a lens at its hyperfocal distance maximizes the depth of field when infinity must be kept sharp.


I
INCIDENT LIGHT/INCIDENT METER: The light that falls on a subject, rather than that which is reflected off it. Many handheld meters are of the incident light reading type. Incident readings are made from the subject with the meter pointed back at the camera.

INFINITY: On a camera lens distance scale, the distance greater than the last finite number, and beyond.

INFRARED FILM: Film which is highly sensitive to red/near infrared radiation. A red filter should be used to get the best effect with this film.

ISO: A prefix on film speed ratings that stands for International Standards Organization, the group that standardizes, among other things, the figures that define the relative speed of films.

TOP 

L
LATENT IMAGE: The invisible image that is formed when the silver halide compounds in film are struck by light. Upon development, this image, or series of light and dark tones, is made manifest.

LENS: A combination of shaped glasses and air spaces set in a specific arrangement within a barrel. Within the lens is a diaphragm that can be opened and closed to allow in specific amounts of light. This is controlled manually by a ring on the outside of the lens barrel, or electronically via pins in the coupling ring that mounts the lens to the camera. Lenses have two primary functions: one is to focus light with as little distortion or aberration as possible on to film or sensor. Focusing is accomplished by changing the relationship of the elements in the lens to the film plane. The other function is to control the amount of light hitting the film by use of its aperture. Autofocusing lenses may contain small motors for racking the lens back and forth in response to changes in focus.

LENS COATING: A thin layer of transparent material applied to glass surfaces in a lens to control light reflections, reduce flare, and increase image contrast.

M
MACRO: Another word for close-up photography, but specifically referring to taking pictures at or near life-size. Can be defined as a ratio; for example, a 1:2 ratio means that the image on film is half-life-size of the object in nature.

MANUAL: An exposure "mode" where the exposure system recommends a setting that is then made by the photographer by selecting aperture and shutter speeds manually. The booklet one doesn't read before using a piece of equipment.

MAXIMUM APERTURE: The widest opening, or f-stop a lens affords. An f/1.4 lens is referred to as fast because it has a relatively wide maximum aperture; an f/4.5 lens is slow because of its relatively narrow maximum aperture. Fast lenses come in handy for hand held low-light photography.

MINIMUM APERTURE: The smallest opening a lens affords. Generally, wide angle lenses have a minimum aperture of f/22; normal lenses of f/16; and telephoto lenses of f/32.

MIRROR LENS: A lens where the light path is bent and reflected internally to increase the focal length of the lens; a simplified system that is usually less expensive than conventional super-telephoto (300mm and up) lenses.

MODE: A way of doing things. Exposure modes are pre-programmed, user-selectable ways of controlling the readings from the exposure system to meet certain subject or picture conditions. These include aperture-priority mode, shutter-priority mode, program-depth mode, etc. Autofocusing modes allow a choice of how the camera/lens will go about autofocusing.

MOUNT: In lenses, a specific set of pins and cams that couple a particular lens to a particular camera body. For photographs, a way of protecting the photograph and giving it a rigid support.


N
NEGATIVE: An image where the tones (recorded brightness values) and, with color film, the colors are reverse of those in the scene. When printed, the negative becomes "positive."


O
OVEREXPOSURE: In exposure, when too much lighting strikes the film for a proper rendition of the scene. Minor overexposure may cause a loss of details or texture in the scene highlights; severe overexposure will cause a serious deterioration of picture quality in color and black and white print film, and a complete loss of picture information with slide films.

OVERRIDES: Making adjustments or intervening to change the camera's autoexposure system reading. Some overrides include exposure compensation and changing ISO ratings.

TOP 

P
PANNING: A shooting technique where the subject is followed during exposure; generally done with a slow shutter speed.

PHOTOGRAPHY: Writing with light.

POLARIZING FILTER: A filter that transmits light waves vibrating in one direction, used to deepen blue sky with color film, tame contrast in very bright scenes, and to ``see'' through reflective surfaces, such as water and glass.

POSITIVE: Another word for slide, as is "transparency". Also, a print from a negative.

PREVISUALIZATION: A thought process that helps a photographer "see" what the photograph will look like on film, and/or a print, done as the picture is being composed.

PROGRAM EXPOSURE MODE: A preset arrangement of aperture and shutter speed that is programmed into the exposure system of a camera to respond to a certain level of brightness when the camera is loaded with a certain speed of film. Custom program modes include Program Wide ( also referred to as Program Depth) chooses a higher aperture at the expense of shutter speed in the exposure equation; Program Tele (or Action) chooses a higher shutter speed at the expense of aperture. Program Normal, or simply Program, is totally camera-controlled and makes all the decisions about aperture and shutter speed settings.

PUSHING, PUSH-PROCESSING: An exposure/processing technique in which the effective speed of the film is raised, coupled with an increase in developing time. In actuality, it is deliberate underexposure of the film with extended developing time that increases density mainly in the highlight areas. Pushing raises the contrast and increases grain, but it can be used effectively for creative and corrective shooting under dim lighting conditions.


R
REFLECTED LIGHT METER: A meter that reads light reflected from the subject. All in-camera meters are of this type.

REFLEX VIEWING SYSTEM: A system of mirrors in an SLR that makes the scene right-reading in the camera's eye-level viewfinder.

TOP 

S
SATURATION: In color, a vividness, or intensity. Some films have more inherent color saturation than others. Saturation can be slightly increased by moderate film pushes, or by slight underexposure of certain slide films. Saturation can be increased in color negative film by moderate overexposure.

SELECTIVE FOCUS: The creative use of focus. Focus can be set so that one plane or subject in a crowded scene emerges, or for sharpness near to far in a scene that covers miles. Selective focus is achieved through the use of various focal length lenses, by altering camera to subject distance, and by changing f-stop settings.

SHADOW: In photography, usually defined as those details or image information contained in the darker areas of a scene.

SHARPNESS: The perception that a picture, or parts of a picture are in focus. Also, the rendition of edges or tonal borders.

SHUTTER: In a focal plane shutter, a set of curtains travels past the film gate and allows light to strike the film within a set period of time. A leaf shutter is located within the lens itself.

SHUTTER RELEASE BUTTON: The button that releases the shutter and ``fires'' the camera. Many shutter release buttons have two stages-slight pressure actuates the meter or autofocus system (or both), further pressure fires the shutter.

SHUTTER PRIORITY: An autoexposure mode where the shutter speed is user-selected and the exposure system chooses an appropriate aperture for correct exposure.

SHUTTER SPEED: An element of exposure; the duration of time in which light is allowed to strike the film.

SILVER HALIDE: A compound containing silver, the crystals of which are the light-sensitive element in film.

SINGLE-LENS-REFLEX: Or SLR. A type of camera that has a movable mirror behind the lens and a ground glass for viewing the image. Film sits behind the mirror assembly, which swings out of the way when an exposure is made. "Single-lens" distinguishes it from TLR, or twin-lens-reflex cameras, where separate lenses are used for viewing and taking.

SLIDE: A positive image on a transparent film base, used for projection viewing, printing, or photomechanical reproduction.

SLOW: A term used to describe a film with a relatively low sensitivity to light, a lens with a fairly narrow maximum aperture, or a shutter speed at or below 1/30 second.

SOFT FOCUS: A picture, or an area in a picture that is left slightly out-of-focus for effect, or a lens or filter that diffuses light and "softens" the overall scene.

SPECIAL EFFECTS: Any technique, lens, filter, accessory, computer effect, use of film, etc. that converts or distorts the "reality" of nature in a picture. Special effects can be sublime or ridiculous, depending on the subtlety with which they're used.

SPEED: With a shutter, the duration of time in which light strikes the film. With film, the sensitivity to light. With a lens, the maximum aperture. All can be described as either fast, medium, or slow speed.

SPOT METERING: Taking an exposure reading from a very select portion of the frame. Cameras with built-in spot metering indicate this portion with a circular ring in the viewfinder screen. Some spot meters have coverage as broad as 8-degrees (this might also be called selective field metering) or, with a handheld spotmeter, as narrow as 1-degree. Many incident meters now have spot metering options. Spot metering is always a reflected light reading, thus is subject to that type of meter's failures.

STOP: A relative measure of light that can be used to describe an aperture or shutter speed, although it is more commonly used with aperture settings. A difference of one stop indicates half or double the amount of light. To stop down means to narrow the aperture; to open up means to expand it.

SYCHRONIZATION,or SYNC: The timing of the firing of the flash to coincide with the opening of the shutter so that the maximum light from that flash records on the film.

TOP 

T
TELEPHOTO: A generic name for a lens with a focal length of higher than 50mm and an angle of view less than 45 degrees (with 35mm format.) A moderate telephoto might be in the 80mm class; a medium telephoto in the 135mm grouping; while a long-range, or extreme telephoto might have a 300mm or higher focal length.

TIME EXPOSURE: A long exposure, usually not handheld, for recording scenes at night or in very dim rooms.

TRIPOD: A three-legged device with a platform or head for attaching the camera, used to steady the camera during exposure. It is most useful for exposures longer than 1/30 second, or when a constant framing must be maintained throughout a series of shots.

TTL: Or Through-The-Lens metering. A flash autoexposure mode that measures light as it reflects off the film plane is referred to as OTF-TTL (off-the-film plane TTL.)

TUNGSTEN-BALANCED: Film that it balanced to reproduce colors faithfully when exposed under artificial tungsten light sources. Also, the lamps that emit that light.


U
UNDEREXPOSURE: Failure to expose correctly because not enough light has struck the film or sensor to faithfully render the color and brightness values. Underexposed pictures are dark; the more the underexposure the darker they become. Color also suffers when film is underexposed, although a slight amount of underexposure can be used to increase color saturation in certain color slide films.

UV FILTER: A clear, colorless filter that stops most ultraviolet rays from recording on film. Handy for shooting distant landscape shots, as it eliminates the bluish haze that might otherwise veil the picture.


V
VARIABLE CONTRAST: A type of black and white printing paper that when exposed under different color light yields different printing contrast grades.

VIEWFINDER: The viewing screen in an SLR on which composition takes place; viewfinders may also contain various guides to exposure, focus, and flash-readiness. In all senses, the control panel from work is done.


W
WASHED OUT: Jargon for seriously overexposed slides, or overexposed highlight areas within slides and prints. It's as if the colors have been diluted to the extent that all pigments have been "washed out."

WARM TONE: The look or mood of a print or slide that tends toward the amber, or yellow/red. In black and white, a brown or sepia-toned print, or a brown-black printing paper.

WIDE-ANGLE LENS: A lens that offers a wide angle of view, usually in the 35 to 24mm focal length range. Ultra-wide-angle lenses range from 20mm to 8mm. Wide-angle lenses also allow use of very deep zones of focus.

Z
ZONE FOCUSING: A way to focus that utilizes the depth of field scale rather than the actual distance from camera to subject. Zone focusing is most useful for candid, street photography.

ZONE SYSTEM: An exposure calculating system based upon previsualizing the scene as a set of tonal variations, and exposing and developing to maximum that tonal set.

ZOOM LENS: A lens on which the focal length can be varied, as opposed to a fixed focal length lens. Zooms come in various focal length ranges, such as 35 to 105mm; all focal lengths including and within this range can be utilized.

Photoshop tips                                                  

1. Specify exact column sizes for text in your Photoshop documents

Photoshop has become a lot more adept at handling text, so it's conceivable that you may actually set a few columns of text in Photoshop. So how do you create consistently sized columns? The answer is simple; just select the Horizontal Type tool (Type tool in version 6) and hold down the [option] key ([Alt] key in Windows) while dragging the mouse pointer to make a text box. Upon doing so, the Paragraph Text Size dialog box opens and you can enter the exact size you want the column to be.

2. Watch out for incompatibility issues between versions of PS

Although you can set a preference in Photoshop to maximize compatibility, unsupported features are discarded when you edit or save an image using an earlier version of Photoshop. For this reason, it's best to work and output your documents in the same version. Before you create a new document that will be viewed and/or printed by someone else, make sure you're working in the same version of Photoshop.

3. A shortcut for adjusting the amount of space between letters in PS

If you want to adjust the letter tracking, or spacing, across a range of letters, you don't have to mess around with entering specific values in the Tracking text box in the Character palette. Instead, you can use key commands.

To tighten the spacing between letters, highlight your text with the Horizontal Type tool (Type tool in versions 6) and then press [option][left arrow] ([Alt][Left Arrow] in Windows); and to add more space, press [option][right arrow] ([Alt][Right Arrow] in Windows).

4. Displaying thumbnail previews in Adobe Photoshop for Windows

You may have noticed that Adobe Photoshop CS for Windows doesn't create thumbnail previews for images. It isn't because you installed the software wrong--previous versions of Photoshop were able to display thumbnail previews using a file named psicon.dll. Unfortunately, this file doesn't install with Photoshop CS. A workaround solution for this limitation is to use Windows Explorer and Photoshop's File Browser. You can display thumbnail previews for some file formats, such as JPEG files, in Windows Explorer; you can display thumbnail previews for all formats using Photoshop's File Browser (File > Browse).

5.Produce type with crisp, resolution-independent edges in Photoshop

Photoshop inherently deals with raster images, which have a tendency to produce jagged edges. However, text starts out as vector shapes and you can preserve the crisp, resolution-independent nature of these lines. To do so, first forgo rasterizing the text in your documents. Second, print to a PostScript printer, which can preserve vector data. Third, save the document as an EPS file if you intend to place it in another application, such as Adobe InDesign. In the EPS Options dialog box, select the Include Vector Data check box.

6. Maximize compatibility of all your Photoshop documents

In Photoshop, you can set a preference to maximize file compatibility between versions. In earlier versions of Photoshop, this preference is on by default, so you probably never even noticed it. In Photoshop CS, however, the preference is set to always ask if you want to maximize compatibility. Are you tired of seeing the Maximize PSD File Compatibility dialog box every time you save a document? Then, the answer is to change the preference setting.

To do this, choose Photoshop (Edit in Windows) > Preferences > File Handling. In the File Compatibility pane, choose Always from the Maximize PSD File Compatibility pop-up menu if you intend to edit your documents in an earlier version of Photoshop. This saves a composite image along with the layers of your documents. It also increases file size considerably. If you don't intend to edit your Photoshop documents in an earlier version, you're better off choosing Never.

7. Switch Add Anchor Point tool to Delete Anchor Point tool quickly

The Pen tool has an Auto Add/Delete option located on the Pen tool options bar. When active, the Pen tool automatically changes to the Add Anchor Point tool when you hover over a line segment. Then, when the Pen tool is directly over a point, it changes to the Delete Anchor Point tool. This is one option you should leave on; it's convenient and saves time.

8. Remove leftover Magic Wand pixels quickly

If the Magic Wand tool never seems to select all the pixels that you want it to, don't try to add the missing pixels to the selection a chunk at a time. Instead, choose Select > Modify > Smooth. In the resulting dialog box, enter 1 in the Sample Radius text box and click OK. This adds the missing pixels to your selection quickly.

TOP

 9. Fill in an object with colour using just key commands

When filling an object with colour, you can select the object and then choose Edit > Fill, or you can simply use a key command. First, with the object selected, set your foreground colour to the desired fill colour. Now, press [shift][option][delete] ([Shift][Alt][Backspace] in Windows) and Photoshop instantly fills your object. This action turns on the Lock Transparent Pixels option and then fills the unlocked areas.

10. Avoid colour shifts when converting RGB to CMYK

A precautionary step you can take to avoid significant colour shifts when converting images from RGB to CMYK is, while working in RGB mode, to set your Proof Set up to Working CMYK. You can do so by choosing View > Proof Set up > Working CMYK. This allows you to work in RGB mode, while seeing the CMYK interpretation of your document onscreen.

11. Use Free Transform to resize an image with specific dimensions

You can resize your selections to an exact measurement using the Free Transform function. Just select the area you want resized. Then, press [command]T ([Ctrl]T in Windows) to access the Free Transform function. Next, go to the tool options bar and enter the appropriate measurements in the W (width) and H (height) text boxes, making sure to follow up the value with inches, pixels, etc. Then, press [enter] to apply your changes.

12. Use the Measure tool to straighten a crooked image

Select the Measure tool from the Eyedropper tool's fly out menu in the Toolbox. Click and drag along an image line that should be horizontal or vertical. Choose Image > Rotate Canvas > Arbitrary, and the correct angle and direction to make that line match the edge of the image frame is displayed. Click OK and Photoshop straightens the image.

13. Create a shape on a new layer

Photoshop automatically fills a shape layer, which you can make with any Shape, Line, or Pen tool, with the foreground colour. However, you can change it to a different colour, gradient, or pattern. Be sure to click the Create New Shape Layer button on the tool options bar. Photoshop stores the shape outline in a layer clipping path that appears in the Paths palette.
TOP
14. Align or distribute linked layers to selection marquee or image space

If you want to align or distribute images on separate but linked layers, you can use either the image frame as a reference point or a selection marquee. Make a selection marquee. Then, switch to the Move tool and click the Align or Distribute button on the tool options bar. The linked images align or distribute as if the selection were the image frame. You can also select Layer > Align To Selection.

15. Sample pixels from more than just the active layer

You can sample pixels from layers other than the active one. To do so, select the Magic Wand, Smudge, Blur, Sharpen, Paint Bucket, or Clone Stamp tool from the Toolbox. Then, select the Use All Layers check box on the tool options bar. The tool you chose samples pixels from all visible layers, not just the active layer.



 16. Use the [esc] key to make Photoshop behave

If you try to use a keyboard shortcut and Photoshop ignores it or delivers an alert message when you know the command should work, you probably have a palette option or a field active. Instead of trying to track down the interference, simply press the [esc] key and try your shortcut again. With any luck, your command will execute as expected.

17. Keep two views of the same document onscreen

When retouching a photograph, it's usually a good idea to keep one view of the image at its actual size while you work on a second view of it at an enlarged size. The changes you make in the zoomed window will appear in the normal-size window. To do so, choose Window > Arrange > New Window [filename] (Window > Documents > New Window in version 7).

18. Save JPEGs as PSDs to preserve quality

If you start with a JPEG image, perhaps from a digital camera, and alter it, don't save it again as a JPEG; you'll lose image quality every time you re-save an image in JPEG format. Instead, save the altered image as a PSD file and make a JPEG copy if you need to post the image to the web, for example. In the meantime, you'll have a good copy of your altered image in PSD format for use in other applications, such as for printing photos or using them a printed brochure.
TOP
19. Export layers to files

New to Photoshop CS is the ability to export layers of a file to individual files by way of the Scripts command in the File menu. In the same menu, you can export layer comps (as flattened images) to flat files in any of six file formats, PDFs, or even images as a Web Photo Gallery for conversion to web pages.

20. Helpful key commands make your work more efficient

Hold down the [spacebar] key and the current tool changes to the Hand tool. Double-click on the Hand tool and the image fills your screen. Double-click on the Zoom tool and the image displays at 100% of its size and resolution on your screen. Press [command][+] or [-] on the keypad ([Ctrl][+] or [-] in Windows) to enlarge or reduce the image and frame by preset percentages: 25%, 33.3%, 50%, 66%, etc.

21. Open a flat version of a layered file

When you want to open a layered file as a flat composite instead, hold down [shift][option] ([Shift][Alt] in Windows) as you open the selected file. Photoshop displays an Adobe Photoshop dialog box that asks, "Read the composite data instead?" Just click OK and your file appears as a flattened version of the layered file.
22. Adjust position of drop shadow with mouse instead of entering values

As you apply a drop shadow layer style, you can use the mouse pointer and drag the position of the shadow to change its angle and distance. You can do this rather than entering number values in the Layer Style dialog box.

23. The number pad acts as a "volume control" with most tools

With the Brush tool active, you can press a number on the number pad to change the brush's opacity--0 equals 100%, 1 equals 10%, and so on. And, regardless of the tool selected, pressing V before the keypad number affects the layer's opacity value.

24. Power key combinations make fills quick and easy

You can open the Fill dialog box anytime by pressing [shift] [delete] ([Shift] [Backspace] in Windows). Pressing [option] delete] ([Alt] [Backspace] in Windows) fills the layer or selection with the foreground colour. Pressing [command] [delete] ([Ctrl] [Backspace] in Windows) fills the layer or selection with the background colour.
TOP

25. Combine all layers into one without losing the individual layers

You can combine all of your layers into one new layer without losing the individual layers. To do so, create a new layer and then press [command][shift] [option]E ([Ctrl] [Shift] [Alt]E in Windows). The new layer then contains a composite of all visible layers.

26. Increase a filter effect with a key command

When you apply a filter in Photoshop and decide that it didn't produce enough of the effect you were after, you can either undo that filter effect and return to the filter's dialog box to reset the values or you can apply the filter again by pressing [command]F ([CtrlF in Windows), which reapplies the filter with the same settings. Better yet, press [command] [option]F ([Ctrl] [Alt]F in Windows) and the last-run filter's dialog box appears so you can fine-tune the settings before you run it again.

27. Use modifier keys to change the function of the Pen tool

Drawing paths in Photoshop is simplified by the fact that the Pen tool can delete and add anchor points all by itself. Depending on how you work, you don't need to select the Add Anchor Point or Delete Anchor Point tool, or even use modifier keys with the Pen tool. With a path selected and the anchor points showing, select the Pen tool and click on an existing anchor point to delete it; use the same Pen tool to click anywhere on a path to add an anchor point.

28. Use the keyboard to switch blending modes

You can switch between blending modes in the Layers palette by pressing [shift][option] and a letter ([Shift][Alt] and a letter in Windows) that represents a blending mode. You must select the Move tool for this feature to work. For example, pressing the key combination with the letter H activates the Hard Light blending mode.


29. Change layer opacity with simple keystrokes

Here's a super-quick way to change the opacity of any layer you're working on without going to the Opacity slider in the Layers palette. With the Move tool selected, simply type a number on the keyboard--1 equals 10% opacity, 5 equals 50%, etc. For intermediate values, such as 74%, just type the two numbers in quick succession.
TOP
30. Use Advanced Blending to remove a black background

You can easily remove the black background from an image--for example, if you want the image to appear as brilliant but over a different background--using settings in the Advanced Blending section of the Layer Style dialog box. Select Gray from the Blend If pop-up menu and move the left sliders individually ([option]-drag to separate them ([Alt]-drag in Windows)) until the darks of the image disappear and the bright colours remain.

31. Position a layer accurately into a new channel

When copying a layer into a new alpha channel, make sure the copied version occupies the exact position of the original. To do this, [command]-click ([Ctrl]-click in Windows) on the layer name to select its outlines. Then, copy and paste into a new channel, which ensures the correct position.

32. Use X key to quickly change painting colour of layer mask

A layer mask starts out with black as the colour that hides and white as the color that reveals. You can quickly switch these settings by simply pressing the X key on the keyboard without having to go to the Toolbox to set either white or black as your foreground color. Pressing the X key toggles the painting colour between black and white.

33. Change the weight of a font with the Maximize and Minimize filters

If you're working with letterforms in Photoshop, you are, of course, limited to some degree by the fonts you own. However, Photoshop offers two ways to at least simulate additional font weights. The first is located on the Character palette. Open the Character palette, highlight a character you've typed, and click the Faux Bold button at the bottom of the palette. This adds a predetermined extra weight to the selected font.

On the other hand, if you want a little more control and you can afford to rasterize your letterforms, Photoshop's filters provide the option to add or subtract weight from a character. Select the character(s) you want to change the weight of, and choose Layer > Rasterize > Type. Now, select Filter > Other > Maximum and adjust the Radius slider to 1 or more pixels. This control does the opposite of what you'd expect: It minimizes the letterform, making it appear thinner. Be careful, though, as there's a limit to how far you can go before the character becomes distorted. Choosing the Minimize filter adds to the weight. You can use these light and heavy weight versions individually or in combination with other artistic or distortion tools.

TOP

34. Sharpen just the edges and leave the rest alone

The Unsharp Mask filter is a wonderful tool if you don't mind increasing the sharpness of everything, including textures. On the other hand, if you want the edges of objects to appear snappier, use the High Pass filter in combination with Unsharp Mask. To do so, duplicate your image and select Filter > Other > High Pass. In the resulting dialog box, adjust the Radius slider to accentuate the edges. Try the lower values first--the image takes on a gray appearance--and work up from there. Click OK. Then, change the Mode pop-up menu in the Layers palette to Overlay and observe the amount of edge sharpening that takes place without affecting the flat or textured areas. If the effect is too strong, try the Soft Light blending mode and/or use the Opacity slider in the Layers palette to reduce the intensity of edge sharpening.

 35. Shift and blend to quickly despeckle an image

You can clean up dirty or speckled areas of an image, particularly the sky or pavement portions of vintage photos, without affecting the parts of the photo that contain people or buildings. Recall the blending modes in the Layers palette: Lighten makes dark spots of the top layer transparent to the lower layer, and Darken makes the light spots of the top layer transparent. Katrin Eisman made good use of this effect in her book "Photoshop Restoration and Retouching".

Using the Lasso tool, capture a segment of a flat, speckled area, feather the edges, and paste it as a new layer on top of the original. If the spots are dark, select Lighten from the Mode pop-up menu in the Layers palette. Using the keyboard arrow keys, shift this image a few pixels to the right and a few down until you notice the spots disappear. You can use the same technique when the spots are a light tone, except choose Darken from the Mode pop-up menu. You can accomplish most of the retouching by using this single technique. It may be necessary to touch up with the Clone Stamp tool to finish the job.

36. Do not neglect the blending mode when using the Pattern Stamp tool

If you're looking for the maximum range of control and the ability to create unique special effects when using the Pattern Stamp tool (located on the Clone Stamp tool's fly out menu), don't forget about selecting a blending mode. The Pattern Stamp tool lends itself to a certain strictness--that is, you're more likely to select a pre-existing pattern and start methodically filling in your target areas. By adding a blending mode to the mix, you'll find that you can create more interesting interactions with the other elements of your design. To select a blending mode for the Pattern Stamp tool, first select the tool and then choose a blending mode from the Mode pop-up menu on the tool options bar.
TOP

37. Know how to read a histogram to spot trouble areas

Now that real-time histograms are beginning to show up on digital camera displays, you need to know how to read them at a glance. Even if you don't have the benefit of a histogram that displays each channel in a different colour, the overall range presented as a black graphic will still give you important information about your picture.

The left side of the histogram represents dark tones. When the vertical bars are clumped toward that end, your image is a low-key photo because most of the information (and pixels) are located in the darker tones. Conversely, when the indicators are clumped to the right end, your image is considered high-key and most of the information is contained in the lighter tones of the photo. A photo with full tonal range shows a distribution of pixels where the middle has a hump and both ends slope down to a decreasing population of pixels. A spike of pixels at the farthest extremes of either end indicates "clipping," which means that a good number of pixels are either too white or too black to have any usable information. Thus, the shadow or highlight information has been lost, or "clipped," from the image. Aside from clipping, or losing good image data, there really is no such thing as an ideal histogram. High-key, low-key, and full-tone are all legitimate methods of image presentation.

38. Turn a shape into a custom brush

Have you ever had to place a series of objects, such as snowflakes or popcorn, into one document? Well, rather than copying and pasting them over and over again, you can turn the shape into a custom brush. To do so, select the object that you want to use as a brush. Then, press [command]C ([Ctrl]C in Windows) to copy the selection. Open a new document and press [command]V ([Ctrl]V in Windows) to paste the image into the new document. Now, choose Edit > Define Brush. In the resulting dialog box, name your brush and click OK. Your custom shape brush now appears in the Brushes palette.

39. Preserve transparent areas when filling an area

Here's a useful trick to help you fill all the pixels with the foreground colour without eliminating transparent areas on the same layer. First, change the Set Foreground Colour swatch to your colour of choice. Then, press [option][shift][delete] ([Alt][Shift][Backspace] in Windows) and the non-transparent areas are filled with your foreground colour, while the transparency is untouched. To fill with the background colour instead, select [command][shift][delete] ([Ctrl][Shift][Backspace] in Windows).

40. Change the painting & editing tool options using only keys

Did you know that you can change the pressure, opacity and/or exposure of the Paintbrush, Airbrush, Pencil, Blur, Sharpen, Smudge, Dodge, Burn and Sponge tools in 10 percent increments by pressing a number on the keyboard or keypad? Well, you can. Just press 1 to change the setting to 10 percent, 2 for 20 percent and so on until you get to 0 for 100.
TOP

41. Scroll through your documents without using the mouse

How often do you find yourself scrolling through 10 or 20 open Photoshop files when working on a project? Normally when you want to access one document or another, you have to click on it to bring it to the foreground. However, an easier and much faster way to do so is by pressing [Control][Tab]. Now, you can go from one document to another in the blink of an eye.

42. Intensify your Clouds effect

If you're familiar with the Clouds filter in Photoshop, then you know that the clouds tend to look more like parchment paper (which is a good thing sometimes). You can navigate to the filter by choosing Filter > Render > Clouds from the menu bar. However, if you want to intensify the effect a bit by adding more contrast, then hold down the [option] key ([Alt] key in Windows) as you select the filter.

 43. Use the Measure tool to straighten out your images

Admit it; you're not always perfect. When scanning images, undoubtedly you've gotten that one scan that was a bit askew when you placed it on the scanner bed. It happens to us all. So, how do you straighten it out? It's easy; simply use the Measure tool. Just drag the tool's pointer along the top edge of your image, then choose Image > Rotate Canvas > Arbitrary. Click OK and Photoshop applies the information from your measurement and straightens things out for you. Now that's perfect.

44. Preview feathering effects

When feathering a selection using the Feather command, there's no way to tell how your final results will appear until you actually apply the feather. So, if you want to preview your effect, you can use a quick mask. To see how it works, open an image in Photoshop. Then, make a selection of the area in your image that you want feathered. Next, press Q to enter Quick Mask mode. Upon doing so, your selection appears red. Now, choose Filter > Blur > Gaussian Blur. In the resulting Gaussian Blur dialog box, you'll be able to preview the effect. So, adjust the blur until you're satisfied with the amount of feathering being applied to your selection and click OK. Press Q again to get your selection back, and then choose Select > Inverse to select the area of your image that you want to delete. Finally, press [delete] and deselect your image for a perfect feather.

45. Merge your layers but preserve your layer styles

Have you ever tried to merge a layer with the layer below it and lost all of the effects applied to that upper layer? This is because when you choose Merge Down from the Layers palette's pop-up menu, Photoshop only applies the blending mode of the bottom layer to the merged version. However, if you select Merge Visible, and hide any layers that you don't want combined, all of your blending modes are preserved and your merged layer will look exactly as is does onscreen.

TOP

46. Take advantage of adjustment layers

Have you ever adjusted the Curves of an image or tweaked the Levels and found the results less than appealing? Or maybe you just wanted to experiment with a few different adjustments without actually applying them to your image. Well, you can do this quite easily using adjustment layers. Just open the Layers palette and click the Create New Fill Or Adjustment Layer button at the base of the palette. Then, select an option from the resulting pop-up menu. Upon doing so Photoshop creates an adjustment layer in the Layers palette, where you can make changes without actually affecting your original image.

47. Add the 3D Transform filter to Photoshop CS

For whatever reason, Adobe didn't include the 3D Transform filter in Photoshop CS. However, you can add it to CS. All you have to do is add the plug-in to the Filters folder. If you still have Photoshop 7's application folder on your hard drive, navigate to the Plug-Ins folder. Open the Plug-Ins folder and then open the Filters folder. Select the 3D Transform filter plug-in and drag and drop it into Photoshop CS's Filters folder (PSCS > Plug-Ins > Filters). Restart Photoshop and choose Filter > Render. The 3D Transform filter is now there for you to use.

If you deleted the old version completely from your hard drive, get the Extras disk that came with the application. Then, navigate to the Optional Plug-Ins folder for Photoshop CS. Next, open the Filters folder and there you'll find the 3D Transform plug-in. Drag and drop it into the Filters folder as we just explained and you're good to go.

48. Resize your paths quickly

After creating a path in Photoshop, you can easily resize the path if needed. To do so, select your path with the Path Selection tool, located in the Toolbox. Then, on the tool options bar, select the Show Bounding Box check box. Doing so places a transform bounding box around your image, which you can then use to adjust the size of your path.


49. Increase your canvas size relatively

The next time you have to increase the size of your canvas, check out Photoshop's Relative option. Just choose Image > Canvas Size. Then, in the resulting Canvas Size dialog box, select the Relative check box. Now, just enter the how much space you want added to the Width and Height text boxes. It's much easier than trying to add 1.57 inches to 22.35 inches (not that you should create documents with such random sizes, but you never know).

50. Add to or subtract from your selections with ease

Oftentimes, when making a selection using any of the selection tools, you may find that you have to add or subtract a portion of the selected area. You can do this easily using key commands. To add to a selection, hold down the [shift] key while making the additional selection. To subtract from it, hold down the [option] key ([Alt] key in Windows).

51. Adjust the tracking of your words and separate letters

Did you know that when typesetting in Photoshop you can fine-tune the spacing between letters or words in your document? Well, you can. To do so, after setting your text, open the Character palette by clicking the Toggle The Character And Paragraph Palettes button on the tool options bar or by choosing Window > Character. In the Character palette, go to the Set The Tracking For The Selected Characters text box and either click on the arrow icon to the right of the text box to assign a preset number or enter a number of your choice. If you want to adjust the spacing between each word, highlight all of your text before making any adjustments. If you want to adjust the spacing between specific letters, just select those letters. Then, adjust the tracking. Now, if you don't want to be bothered with actual numeric values, adjust the tracking space by space using key commands. Just highlight the text you want to modify, and then press [option][left arrow] ([Alt][Left Arrow] in Windows) to make the spacing tighter or [option][right arrow] ([Alt][Right Arrow] in Windows) to space out the text more.

52. Change colours of your images in the blink of eye

How many times have you been asked to change the colour of an element within an image? The next time this happens, we've the the perfect technique for you. Just select the area of the image that you need to change. Then, choose Image > Adjustments (Adjust in version 6) > Hue/Saturation. In the resulting dialog box, select the Colorize check box, and then drag the Hue slider back and forth until you get the colour you want. It's that easy!

 53. Sample wisely with the Eyedropper tool

The Eyedropper tool is great to use when you want to take a colour from one part of an image and use it somewhere else. With that said, when sampling colours, for the best result, set the Sample Size pop-up menu to 3 By 3 Average on the tool options bar. This will give you a nice colour representation.

 54. Using digital sticky notes on your files

Did you know that you can attach notes to your Photoshop files without exiting the application? Well, you can. The next time you have a file that's going to be modified by another designer or reviewed by someone else, and you want to include a note, just attach a digital annotation to it. To do so, select the Notes tool from the Toolbox and click on your document where you want the note to appear. It's that easy! Also, keep in mind that these notes are compatible with Adobe Acrobat.

55. Resolving memory issue when using filters

Filters take up a lot of memory, especially when you apply them to large files. If you've found that Photoshop gets a bit choked up when you apply filters, there are a couple of ways to help things run more smoothly. First, try to apply the Purge command by choosing Edit > Purge > All. If that doesn't help, try just applying the filter to a small selected portion of your image to preview the results before actually applying it to the entire image. Finally, as a last resort, try applying the filter to individual channels, rather than the composite channel.

 56. Duplicate your documents in the blink of eye
When photo retouching, you should always keep a copy of the original image, just in case you have to go back to it for any reason. With that said, a fast and easy way to duplicate an image that you want to adjust is to simply choose Image > Duplicate. In the resulting Duplicate Image dialog box, name the duplicate image and click OK. Upon doing so, Photoshop opens the new document and you can retouch it without worrying about altering the original image.

57. Make an image catalog using an automated task

Do you have a lot of images stored on your computer or CDs that you're constantly sifting through to find what you want? If so, you should take advantage of Photoshop's ability to create contact sheets. Basically, this feature allows you to print out thumbnails of all your image files stored in a folder, including images in subfolders. Even more importantly, you can print the filename along with the thumbnail. Then, when you want a certain image, just glance through your thumbnail printouts, find the image you want, and then access it on your computer.

To make a contact sheet, choose File > Automate > Contact Sheet II. In the Contact Sheet II dialog box, select the folder containing your images from the Source Images section. Then, adjust the document settings for your needs and enter how you want your thumbnails to be laid out. Finally, select the Use Filename As Caption check box and choose a Font and Font Size. Click OK and let Photoshop go to work creating your contact sheet.

 58. Add a border around your images

Every once in a while you may find that you have to add a 1-point border around your Photoshop files. There are a couple of different ways you can do this. The quickest way is to select the entire document and add a stroke around it. To do so, open the Layers palette, and if your image is on the Background layer, convert it to a working layer by double-clicking on it. Then, click the Add A Layer Style button and choose Stroke from its pop-up menu. In the resulting Layer Style dialog box, set the Size slider to 1 and the Position pop-up menu to Inside. Then, in the Fill Type section, choose the colour you want your stroke to be. Click OK and you'll have an instant frame.

If you don't want to cover up any part of your image, you can add an outer frame to your image by making the canvas larger. First, set your background colour to whatever colour you want the stroke to be. Also, for this technique, make sure your image is on the Background layer. Then, choose Image > Canvas Size. In the resulting Canvas Size dialog box, change the Width and Height measurement increments to pixels. Then, increase both the Width and Height by 1 pixel. Leave the remaining settings as they are and click OK. Photoshop automatically fills the outer pixels of your canvas with your background colour.

59. Fill your document using only key commands

There are a number of shortcut key commands you can use to fill your documents. They are as follows:

* If you want to fill a layer with your foreground colour, press [option][delete] ([Alt][Backspace] in Windows).

* To fill a layer with your background color, press [command][delete] ([Ctrl][Backspace] in Windows).

* To fill a layer with black, press the D key followed by [option][delete] ([Alt][Backspace] in Windows).

* To fill a layer with white, press the letter D followed by the letter X and then [option][delete] ([Alt][Backspace] in Windows).

60. Hide that distracting checkerboard pattern

Working with an image on a transparent background can be rather frustrating because of the annoying checkerboard pattern that signifies transparency. This is especially true if the image is gray scale and you're trying to do detail work. To hide the checkerboard, press [command]K ([Ctrl]K in Windows) to display the Preferences dialog box. Then, select Transparency & Gamut from the main pop-up menu that's set at the default of General. In the Transparency Settings section, select None from the Grid Size pop-up menu and click OK.

61. Save your selections for future use

Have you ever created a selection and deselected it only to discover you need the selection again? Well, rather than wasting time reselecting it all over again, just save your selection. To do so, make your selection, and then while it's still active, choose Select > Save Selection. In the resulting Save Selection dialog box, name the selection and click OK. Now, when you need to access that selection, choose Select > Load Selection. In the resulting dialog box, choose your saved selection from the Channel pop-up menu and click OK.

62. Replace old colours with new colours

The latest and greatest version of Photoshop has added a new tool for you to abuse--the Colour Replacement tool. Using this tool you can make quick colour changes in seconds. To see it in action, open a document to experiment on. Then, choose the Colour Replacement tool from the Toolbox (it's hidden on the Healing Brush tool's fly out menu). Then, go to the tool options bar and set the Mode pop-up menu to Colour, the Sampling pop-up menu to Once, and the Limits pop-up menu to Find Edges. Also, adjust your brush settings if necessary. Next, [option]-click ([Alt]-click in Windows) on the colour you want to replace. Now, click on the Set Foreground Colour swatch in the Toolbox and choose a new colour to use in your image. Finally, just paint away the old colour with the new. It's that easy!

63. Make smoke with ease

Have you ever needed to add smoke to an image and struggled to come with an easy way to do so? Well, now you don't have to even think about it. To make instant smoke in Photoshop, first open a new document and fill the Background layer with black. Next, create a new layer to work on in the Layers palette and name the layer Smoke. Using a small, round brush tip, paint a white vertical strip in the centre of your document. Then, use the Smudge tool to push and pull your line around until it looks like smoke. The more you smudge, the better your smoke will look.

64. Preview your Web images before you save them

When using the Save For Web command, you can preview how your images will appear on both a PC and a Mac. To do so, select File > Save For Web. In the resulting Save For Web dialog box, click on the arrow icon located in the top-right corner of the preview area. Then, select the platform in which you want to see your image.

65. Take snapshots of your work for precautionary measures

When you're working on an extensive project in Photoshop, it's always a good idea to take a few snapshots as you go. That way, if you want to backtrack or something goes awry, you can click on a snapshot and get to work again. To create a snapshot, open the History palette and click the Create New Snapshot button at the base of the palette (it's the little camera icon). Upon doing so, Photoshop places a saved version of your file in the History palette. Then, if you need to access that image, just click on it.

66. Rasterize all of your text at once

If you have multiple layers of text that all has to be rasterized, you can do it in one fell swoop. Just choose Layer > Rasterize > All Layers. That's all there is to it!

67. Use the Background Eraser tool to its maximum capacity

The Background Eraser tool is great for removing unwanted backgrounds in an image. However, at times it can be trying to keep the tool where you want it as you erase. So, to make things much easier and more efficient, create a path around the object. First, select a large hard-edged brush from the Brush pop-up window on the tool options bar. Then, select the Pen tool and outline the object; make sure the path falls just outside of the object's edges. Next, choose Stroke Path from the Paths palette's pop-up menu. In the resulting dialog box, choose Background Eraser from the Tool pop-up menu and click OK. Photoshop automatically removes the edges around your image so you can go ahead and quickly erase the remaining background with ease.

68. Scroll through the different colours modes in the Colour palette

When selecting a colour for your designs, you don't have to use the Colour Picker at all; instead, you can use the Colour palette. To access the palette, choose Window > Colour. Then, if you want to select colours in Gray scale, RGB, or CMYK, [shift]-click on the colour bar at the base of the palette until you get the one you want and select a colour. You can also select a different colour mode from the Colour palette's pop-up menu.

69. Make circular selections from the centre out

Typically, when using the Elliptical Marquee tool, Photoshop draws your selection from wherever you click the mouse initially. However, if you want to create a selection going from the centre out, you can do so by holding down [shift][option] ([Shift][Alt] in Windows) in Photoshop 7.x and CS, or hold down just the [shift] key in version 6.x.

  70. Add a stroke to a path in seconds 

To add a stroke to a path, all you have to do is create your path. Then, select the brush you want to use for your stroke and press [enter]. Photoshop automatically strokes your path using the brush you selected.

71. Run your text along a path

Did you know that Photoshop CS allows you to run text along a path? Well, it does! Just create a path using the Pen tool. Then, select the Horizontal Type tool and click the insertion point on the path where you want your text to start. Finally, just type away
.
72. Make part of a colour image stand out by surrounding with gray imagery

A great way to draw attention to one portion of an image is to make it the only colour object surrounded by gray imagery. A quick way to achieve this effect is to open a colour image. Then, set your foreground colour to black. Next, select the Brush tool (Paintbrush tool in version 6.x) and change the Mode pop-up menu from Normal to Colour on the tool options bar. Now, using a soft, round brush, paint over the portion of your image you want to make gray scale. That's all there is to it!

73. Stay on target with Photoshop Navigator palette 

When up close and personal with an image, zoomed in at around 300% or closer, it's rather easy to lose track of where you are. To avoid getting lost in enlarged pixels or having to reduce the image size and then zoom in again, use the Navigator palette instead. You can display the palette by choosing Window > Navigator. A thumbnail of your entire image will appear within the palette along with a red border that frames in the area you're working on. If you want to move from one area to another in your image, just click inside the red frame and drag where you want to go. As you do this your image moves in the same direction.

74. Quickly straighten out crooked images in Photoshop 

Every once in a while you may have to straighten out an image that's a bit skewed. There are a number of ways you can do this. For example, you could use the Crop tool or the Rotate tool. However, the fastest and most accurate method to use when straightening an image involves using the Measure tool. To see how it works, select the Measure tool from the Toolbox. Then, within your image, drag the pointer along a horizontal line that you want to be straight. Next, choose Image > Rotate Canvas > Arbitrary. In the resulting dialog box, leave the settings as they are and click OK. Photoshop automatically rotates the canvas for you, aligning your image with the line you drew using the Measure tool.

75. Apply more than one mask to a layer in Photoshop

Have you ever wanted to incorporate more than one layer mask on a layer? Well, you can! Just add your first layer mask in the Layers palette as you normally would. Then, place that layer into a layer set and create a mask for the layer set. It's that easy!

76. Make your background layer a working layer in Photoshop

Have you ever tried to apply a layer style to a Background layer? If so, then you know it isn't possible. However, you can make the Background layer an actual working layer by simply double-clicking on it in the Layers palette. When you do, the New Layer dialog box displays. Name the layer and click OK. You'll now be able to apply any layer style that you want.

77. Rasterize all your type layers at once in Photoshop 

When working on a document with multiple type layers, you can rasterize all of those layers at once when the time comes. Just choose Layer > Rasterize > All Layers. It's that easy.

78. Quickly undo an accidental save in Photoshop 

Have you ever flattened and saved a document and then wanted to go back and make a change? If so, you can undo that save using a keyboard shortcut. Just press [option][command]Z ([Alt][Ctrl]Z in Windows) a few times until your file is back the way you want it.

79. Paste your images where you want in Photoshop 

When copying and pasting images from one document to another, Photoshop places them in the centre of the new file by default. However, if you make a selection on the new document where you want the image to go, Photoshop centres the pasted image within that selection.

TOP  

80. Resize your paths quickly in Photoshop 

After creating a path, you can easily resize it if needed. To do so, select your path with the Path Component Selection tool. Then, select the Show Bounding Box check box on the tool options bar. This places a transform bounding box around your image, which you can then use to adjust the size of your path.

81. Use the Fill command shortcut in Photoshop 

Typically when you want to fill an image you have to choose Edit > Fill to access the Fill dialog box. However, did you know that you can display this command using a key command? Just press [shift][delete] ([Shift][Backspace] in Windows).

82. Put a new layer below the selected layer in Photoshop Layers palette

Have you ever wanted to place a new layer below the one that's currently selected in the Layers palette? If you have, then you know that by default Photoshop 7.x always places new layers above the active layer. If you hold down the [command] key ([Ctrl] key in Windows) while clicking the Create A New Layer button at the base of the Layers palette, the new layer is placed below your active layer.

83. Change colours in your image with ease using Photoshop

Have you ever wanted to make a red flower pink? Well, it's easier than you might think with Photoshop. Simply select an area of your image that you want to modify. Then, choose Image > Adjustment (Adjust in version 6.x) > Hue/Saturation. Next, select the Colorize check box and drag the hue slider back and forth until you locate the new colour you want the area to be. Then, just click OK.

84. Close a dialog box immediately in Photoshop

Have you ever opened a dialog box only to discover that it's the wrong filter or you didn't select the right area in your image to apply the effect to? Well, you can quickly close the dialog box without applying any effects to your image by pressing the [esc] key.

85. Reposition shapes while creating them in Photoshop

When using one of Photoshop's Shape tools, you'll find that once you click on your document and start drawing the shape you can't reposition it. Or can you? Of course you can! To do so, begin drawing your shape. When you need to reposition it, hold down the [spacebar] key and move your shape with the mouse. Then, release the [spacebar] key and continue drawing your shape.

86. Access Photoshop Brushes palette with ease in Photoshop 7

Years ago, Photoshop had this great keyboard shortcut to access the Brushes palette. But, with the release of version 6.x, this shortcut disappeared. However, all is back to normal in version 7. To open the Brushes palette in the blink of an eye, simply press [F5].

87. Quickly lighten or darken your images using the Levels feature

Have you ever had to lighten or darken an image? Well, a great way to do this is by adjusting the image's Output Levels. To see how it works, open an image in Photoshop. Next, press [command]L ([Ctrl]L in Windows) to access the Levels dialog box. Then, to lighten the image, drag the black Output Levels slider toward the right. To darken the image, drag the white Output Levels slider to the left. Then, when you're happy with the results, click OK. That's all there is to it.

88. Change your Photoshop ruler settings in seconds

If you have your rulers visible, all you have to do to adjust the ruler settings is double-click on the actual ruler. This displays the Preferences dialog box, where you can then adjust the rulers (and units) settings.

89. The return of the Brushes palette in Photoshop v7.x

Photoshop 7.x offers a whole new workflow, but in some respects, it's returned to its old ways. The best example is the return of the Brushes palette, which disappeared in version 6.x as a pop-up menu on the tool options bar. The Brushes palette can be accessed in version 7.x by selecting Window > Brushes. The Brushes palette is titled Brush Presets, and operates more like a dialog box than a palette. That is, when you're done making your adjustments and return to your image, the palette disappears. This can be a challenge to get used to, but the extensive options grouped in this one palette make it a valuable feature.

To tell you everything the Brushes palette can do is a topic for a complete article, but in this tip, let's take a quick look at how you create a basic new brush. Select the inverted arrow next to the active brush in the tool options bar and then click on the Brush Preset Picker to display the menu. By selecting New Brush from the menu, the Brush Name dialog box opens. Give your brush a name and click OK.

Huh? No New Brush dialog box? Well, this is where making a new brush in Photoshop 7.x gets a little weird. Your new brush is saved with the settings of the active brush, so you really have a duplicate brush at this time. Select the last brush in the brush list and open the Brushes palette. Now, click on the Brush Tip Shape menu choice in the palette and you'll see some of your familiar settings again. Use these settings and the many other options available in the Brushes palette to create your brush. When you're done making your selections, return to your image and start working; your new brush attributes are automatically saved.

90. Filling a beyond-the-bounds object in Photoshop

To change the colour of an object that extends beyond the boundary of the canvas, don't make a selection at all. Instead, click the Lock Transparent Pixels button for that layer and then fill it with a new colour. This changes the colour of the entire graphic, even the part that's unseen.

91. Change your selections into paths using Photoshop

Did you know that you can convert any selection you make in Photoshop into a path? To do so, just create a selection. Then, go to the Paths palette and click the Make Work Path From Selection button at the base of the palette or choose Make Work Path from the palette's pop-up menu. It's that easy!

92. Create a flattened version of your Photoshop layers in seconds

Rather than actually flattening your entire document to see how things will look or to experiment on, you can quickly create a layer containing a flattened version of your work. To do so, create a new layer in the Layers palette. Then, hide any layers that you don't want in the flattened version by clicking the Eye icon next to the layer so that it's no longer visible. Now, with your newly created layer selected, hold down [command][option] ([Ctrl][Alt] in Windows) and choose Merge Visible from the Layers palette's pop-up menu. Your new layer now contains all of the layers you left visible.

93. Add a splash of colour to gray scale images in Photoshop

Creating monotone images has never been easier. To quickly add an overall hue to a gray scale image, first make sure that the image is in RGB mode. Then, choose Image > Adjustments (Adjust in version 6.x) > Variations. Now, just click on the thumbnail that's the colour you want your image to be. Then, click OK to apply it.

94. Set up your palettes for easy access in Photoshop

Did you know you can access many of your palettes in Photoshop using function keys? The benefit of this is that you can show or hide specific palettes to free up desktop space when you work. By default the Colour palette's function key is [F6], the Layer palette's key is [F7], the Info palette's key is [F8], and the Actions palette's key is [F9]. Because not every palette has a function key, you can dock certain palettes together so they'll be affected the same way as a palette with a function key. For example, dock the Swatches palette with the Colour palette. Then, press [F6] to hide the palette and press [F6] again to display it. As you can see, this brings up both palettes. By arranging your palettes in this manner, you'll save time and help maintain a tidy workspace. It's definitely worth it.

95. Lighten and darken portions of an image in Photoshop

Enhancing the colours in an image can be a relatively simple process. Do not believe us? Try it for yourself; open an RGB image to work on. Then, create a new layer in the Layers palette. Now, choose Edit > Fill. In the resulting Fill dialog box, choose 50% Gray from the Use pop-up menu and click OK. Now, in the Layers palette, change the blending mode of the layer to Colour Burn to darken the image so that it's over saturated. Also, lower the Opacity of the layer to 70%. Next, select the Brush tool (Paintbrush tool in version 6.x) with a soft, round tip. Then, on the tool options bar, set the brush's Opacity to 20%. Also, make sure the foreground colour is set to white. Now, paint over the areas you want to lighten. It's colour correction made easy!

96. Quickly add contrast to an image in Photoshop

When working with gray scale images that are lacking contrast, you can apply a Levels adjustment layer for a quick fix. To see how it works, open an image in Photoshop. Then, in the Layers palette, click the Create New Fill Or Adjustment Layer button and choose Levels from its pop-up menu. In the resulting Levels dialog box, leave the settings as they are and click OK. Now, change your adjustment layer's blending mode from Normal to Hard Light in the Layers palette. At this point, you can fine-tune your results by double-clicking on the Levels thumbnail in the Layers palette and adjusting the mid tone, shadow, and highlight sliders.

97. Clean up spotty images using Blur tool

If you have an image that's laced with small, random spots, dust, and scratches, you can use the Blur tool to remove them. To do so, open your image in Photoshop. Then, create a new layer to work on in the Layers palette. Select the Blur tool from the Toolbox and select the Use All Layers check box on the tool options bar. To erase light spots, set the tool's Mode to Darken on the tool options bar, and to eliminate dark spots, set the mode to Lighten. Then, just click and hold the tool over the problem spots until they're gone.

98. Turn your photos into drawings using Photoshop

Have you ever wanted to turn a photograph into a sketch? If so, there's a really easy way to do so. Open an RGB image in Photoshop. Then, choose Filter > Stylise > Find Edges. Now, choose Image > Adjustments (Adjust in version 6.x) > Desaturate. That's all there is to it!

TOP  

99. Change your brush cursor quickly in Photoshop

When using the Brush tool (Paintbrush tool in version 6.x), there are times when you have to do detailed work and times when you're making broad changes. Because of this, Photoshop provides you with different brush cursor displays--Precise and Brush Size. To quickly switch back and forth from one to the other, just press the [caps lock] key.

100. View your image in two colour modes simultaneously

When creating a document that will eventually be converted from RGB to CMYK, it can sometimes be difficult to picture how the colours will look upon conversion. To eliminate any guesswork, why not work on your RGB document while previewing it in CMYK?

To do so, open an RGB image in Photoshop. Then, choose Window > Documents > New Window. Doing so opens a second view of your document. Next, choose View > Proof Set up > Working CMYK. Now go back to your original document and work away while previewing everything in CMY
