USING PHOTOSHOP ELEMENTS 8
Glossary

Any of several methods for achieving a smooth transition between two adjacent colors, including black and 

white.

A predefined profile that determines how best to display and print grayscale images for a 

given color setting.

A single-channel image that includes only black, white, and shades of gray. Depending on the bit depth, 

grayscale images can reproduce various shades of gray.

A monochrome image made up of variably sized dots simulating the shades of gray in a photograph. It is used 

for reproducing photographs on PostScript printers and printing presses.

The lightest and darkest colors in an image.

The brightest elements in an image. (See also “

A bar chart showing the distribution of the pixel values in a digital image. The horizontal axis represents 

levels from 0 (darkest) to lightest (255), and the vertical axis represents the numbers of pixels at each level.

An image state listed in the Undo History panel.

An area in which light is concentrated to such a degree that all detail is lost; that is, an area that is blown out 

to white.

A color mode that is based on the human perception of color and describes it according to hue, saturation, and 

brightness.

The color reflected from or transmitted through an object. In common use, hue is the property that allows a color 

to be distinguished as red, blue, yellow, and so on; the “color of a color.”

Sets the rate at which the stroke color switches between the foreground and background colors. Higher 

values cause more frequent switches between the two colors than lower values.

International Color Consortium. ICC device profiles are the industry standard for reproducing colors accurately 

Image Color Management, is Windows’s built-in color management system that uses color profiles for images 

and devices such as scanners or printers. Similar to Apple’s ColorSync on Mac OS.

A measure of the light falling upon a subject in a photograph.

A section of hard disk space used as virtual memory. The image cache speeds the on-screen redraw of 

high-resolution images.

The color mode of an image, such as Grayscale or RGB.

A color that is rendered by using a pixel value as an index to a panel of 256 or fewer colors for 

interpretation. 

Video generated by a system developed for early television and still in use in standard television 

displays. Video is displayed on-screen at 30 frames per second (NTSC) or 25 frames per second (PAL). Each frame is 
divided into two interlaced fields, each displayed for 1/60 of a second. The odd field contains all the odd-numbered 
scan lines, and the even field contains all the even-numbered scan lines of a video frame. The human eye perceives the 
information in two sequential interlaced fields as one unified frame. (See also “
