Setting the Gray Balance

Neutral shades of gray are produced by mixing the three colors

used to make up the image in approximately equal

proportions. Sometimes, however, the resulting gray shades

are not truly neutral. To create a more neutral gray, adjust the

Gray Balance

setting.

Choose the left Color button below the

Gray Balance

slide

bar; the mouse pointer changes to an eyedropper icon. Select

the color in the preview scan you want to neutralize. Then

either move the slide bar to adjust the color or choose the

Comparison icon to the left of the slide bar to choose the level

you want from the comparison samples. The

Gray Balance

value field shows the setting for the selected color or you can

type a specific value in the field.

Changing Saturation

Changing the saturation levels of a color increases or decreases

the amount of color in a specific hue. Less saturated colors are

more pale while saturated colors are richer.

You can change the saturation levels in the image by adjusting

the

Saturation

slide bar. You can also click on the Comparison

icon to the left of the slide bar to choose the saturation level you

want from the comparison samples. The

Saturation

value field

shows the setting you selected or you can type a specific value

in the field.

To remove color from an image completely, move the

Saturation

slide bar all the way to the left.

Note:

The saturation setting is ignored during 3-pass scanning.
