CONFIGURING THE ONETOUCH BUTTONS 63
■ Color Filter—Color filter is the ability of your scanner to
automatically remove a color from a scanned item. For example, if
you are scanning a letter with a red watermark, you can choose to
filter out the red so the scanned letter just shows the text and not
the red watermark. Color filter applies to Black&White or
Grayscale Mode.
8. Click the Advanced Settings tab.
The options of the Advanced Settings tab are for the Color or
Grayscale scanning mode.
Saturation is the strength or purity of a color, hue is the color your
eyes see as reflected from the image, and gamma controls the
brightness of the midtones of the color.
9. Drag the sliders to the left and right to change the color settings. As
you do, the image changes to show the effects of the new settings.
