Saturation Bar - Microtek ScanMaker 4700 User Manual

Color Correction tool
Radius
This field shows the amount of shift towards a particular color and works in
tandem with the Angle field. The Radius range extends from 0 located at
the center of the Color Wheel and indicating the least concentration of
color, to 1, located at the periphery of the Wheel and indicating the
greatest concentration of color.
Example: If your angle is 0° (red on the Color Wheel) and the radius is 1,
this results in an intense reddish cast on the entire image.
The Angle-Radius feature works differently from that of the Saturation bar,
which increases the saturation of all hues in the image without tending
towards any particular color cast.

Saturation bar

This lets you change the intensity of the hues (colors) in your image. Use
Saturation selectively, because increasing saturation will increase the
intensity of all hues in the image.
Using the Color Wheel:
1. To change the hue of an image, move the pointer in the color wheel
to its new color position in the wheel.
2. To change the saturation of an image, drag on the saturation slide
bar. Dragging the slide bar to the left decreases saturation; dragging
it to the right increases saturation.
