Using the Spectral Equalizer
The Spectral Equalizer is used to increase or decrease the saturation of
specific color ranges in the active image. It works on the same principle
as a graphic equalizer on your home stereo.
Each of the 13 points allow you to enhance a particular range of color.
Dragging a selection point up or down will saturate or neutralize (make
gray) the particular color range under the point.
To remove all color from the image, press the Neutralize button.
To return to the default, click the Normalize button.
To completely saturate the image, click the Saturate button.
ScanTastic allows you to easily locate a color range in the equalizer by
simply moving the pointer over a specific area of your image and
clicking while you press the Option key on your keyboard.
