USING PHOTOSHOP ELEMENTS 8
Glossary

An unwanted or unexpected color shift in a photo. For example, a photo taken indoors without a camera 

flash may have too much yellow.

The component colors from which all colors in an image are created. Usually refers to red, green, and 

blue (RGB).

Measures how much color information is available to display or print each pixel in an image. Greater color 

depth means more available colors and more accurate color representation in the digital image.

The range of colors that a device can reproduce in any given color space.

A system used to index or reference colors when the bit depth is insufficient to represent all 

colors. 

A system used to achieve consistent color as an image travels from one device to another (for 

example, from camera to computer, and computer to printer).

Determines how the components of a color are combined, based on the number of color channels in the 

color model. Color modes include grayscale (1 channel), RGB (3 channels), and CMYK (4 channels), among others. 
Photoshop Elements supports bitmap, grayscale, indexed, and RGB color modes.

Any system for specifying the components of color. The main color models are RGB, CMYK, and HSB.

The conversion of RGB color data into CMYK data for printing.

A color mode designed for a particular device or purpose. For instance, Adobe RGB is the color space used 

by Adobe applications, and sRGB is the color space used by most monitors. Color spaces are important in color 
management, where the color profile of an image is reconciled with the color space of the application or device on 
which it is viewed. The color space used by Adobe applications is sometimes called the working space.

(1) The position of a color along a continuum from warm (red) to cool (blue). (2) The degree of 

heat (in degrees Kelvin) that an object would have to absorb before it glowed in a certain color. Each color is associated 
with a color temperature, as are various kinds of light. 

A mathematical description of the color of a pixel determined from its color components. 

A representation of the colors in the visible spectrum arranged in a circle so that complementary colors 

are directly opposite each other.

Color management software provided by Apple. 

Refers to any menu item you choose to perform a desired operation.

Two colors of light that, when combined, create white light, or two colors of ink that, when 

combined, create black. Complementary colors are opposing colors on a color wheel.

Multiple photos combined into a single image. 

A technique that reduces the file size of bitmap images.

Any layer in Photoshop Elements that contains an image, text, or object.

The difference in brightness between light and dark areas of an image. Contrast determines the number of 

shades in the image.

The colors at the blue end of the spectrum.

A font technology from Adobe that improves on-screen text resolution.

An internal part of an Adobe PDF file.
