Strip of grey values ranging from white to black. Used by process camera and scanner operators to calibrate exposure times for film and plates. Also called step wedge.
The perceptable degrees of black below 100% coverage. The 8 bit scale can cover some 256 different shades.
The ability of a black-and-white printer or screen to display shades of grey.
a range of luminance values for evaluating shading through white to black. Frequently used in discussions about scanners as a measure of their ability to capture halftone images. Basically the more levels the better but with correspondingly larger memory requirements.
A calibrated sequence of grey tones ranging from black to white.
A strip of standard grey tones, ranging from white to black, placed at the side of original artwork during photography to measure tonal range and contrast obtained on the copy.
is the use of many shades of gray to represent an image. Continuous-tone images, such as black-and-white photographs, use an almost unlimited number of shades of gray. Conventional, however, can only represent a limited number of shades of gray (typically 16 or 256).

The range of steps between black and white that can be separately identified within an image.
