Adaptive Palette - a custom palette derived from actual colors in an image.

Adjustment layer - lets you experiment with color or tonal adjustments to an image without permanently modifying the pixels in the image.

Anti-alias - the process of smoothing the edges of an object or text to blend with the background.
Bit Depth - the number of colors assigned to each pixel and visible on the monitor.
Bitmap Mode - This mode uses one of two color values (black or white) to represent the pixels in an image.
Channel - 8 bits of grayscale information, which can be used to define red, green, and blue channels of a RGB mode image, or a channel mask.
Clipping group - the bottommost layer, or base layer, acts as a mask for the entire group.
Clipping path - lets you isolate the foreground object/image and make everything outside the object transparent when the image is printed or placed in another application.
Clone stamp - let you sample part of an image and then paint with the sample.
CMYK model (subtractive colors) - The CMYK model is based on the light-absorbing quality of ink printed on paper. As white light strikes translucent inks, part of the spectrum is absorbed and part is reflected back to your eyes.
Crop tool - a tool that enables you to retain the subject of an image, and remove the unselected image areas.
 
word up

Defringe command - replaces the color of any fringe pixels with the colors of nearby pixels containing pure colors.

Desaturate command - converts a color image to a grayscale image in the same color mode.
Duotone Mode - This mode creates duotone (two-color), tritone (three-color), and quadtone (four-color) grayscale images using two to four custom inks.
Encapsulated PostScript (EPS) - language file format can contain both vector and bitmap graphics and is supported by virtually all graphic, illustration, and page-layout programs.
Gamut - the range of colors that a color system can display or print. A color that can be displayed in RGB or HSB models may be out-of-gamut, and therefore unprintable, for your CMYK setting.
Graphics Interchange Format (GIF) - a file format that uses 8-bit color and efficiently compresses solid areas of color while preserving sharp detail, such as that in line art, logos, or illustrations with type.
Grayscale Mode - This mode uses up to 256 shades of gray. Every pixel of a grayscale image has a brightness value ranging from 0 (black) to 255 (white).
HSB model - describes three fundamental characteristics of color: hue, saturation and brightness.
Indexed Color Mode - This mode uses at most 256 colors (limited palette). When converting to indexed color, Photoshop builds a color lookup table (CLUT), which stores and indexes the colors in the image.
