DJUSTING THE

Most scanning software offers a common group of

scanning settings to help you get the results you

want. Many also provide a preview function that

lets you see a sample of what the finished scan will

look like and check the settings. You may have to

experiment a few times to get the results you want,

but you'll soon be adept at making minor

adjustments to fine-tune your scanned image.

OLOR

When you scan a color image, you usually want

the tones and colors to be as close to the original

as possible. Two software functions are particularly

helpful for matching your original: gamma

correction and color correction. Gamma

correction lets you adjust the light intensity (or

tone) in the scanned image so that when it is

reproduced-either on your monitor screen or a

printer, the resulting image has similar gradations

to the original. (The term gamma refers to a curve

on a graph that measures the degree of contrast

between light and dark.)

Color correction adjusts the color information so

that the colors in the reproduced image are close

to the original colors. For example, a typical CRT

display uses a combination of red, green, and blue

to produce the entire range of colors. On the other

hand, a color printer usually uses magenta, cyan,

and yellow (and sometimes black) to produce

the same range of colors. The color correction

function processes the image data for the specific

characteristics of the color output device you use,

to produce it.
