Setting the Gray Balance Intensity
Neutral shades of gray are produced by mixing the three colors in 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 Intensity setting.
Click the left Color button below the Gray Balance Intensity slide bar; the mouse pointer changes to an eyedropper. Select the color in the preview image you want to neutralize. Then either move the slide bar to adjust the color, or click the Comparison icon next to the slide bar to choose the coloring you want from the comparison samples. The rectangle to the right of the Color button shows the result of your color adjustment.
Changing Saturations
Changing the saturation level 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 preview image by adjusting the Saturation slide bar. You can also click the Comparison icon next to the slide bar to choose the saturation level you want from the comparison samples.
To completely remove color from an image, move the Saturation slide bar all the way to the left.
Note:
The Saturation setting is ignored if 3 pass is selected as the Scanning Sequence in the Image Type dialog box.
