Brightness/Contrast; Hue/Saturation - Microtek ArtixScan DI 1210 Reference Manual

Brightness/Contrast

The Brightness/Contrast control is active only when the Attribute setting of the
selected frame image is Photo. Brightness/Contrast lets you control the brightness
and contrast levels of the selected frame image.
Increasing the brightness makes all tones in the image lighter. Contrast, on the other
hand, is the range between the darkest and lightest shades in the image, and
increasing the contrast makes for greater separation between the darkest and lightest
areas of the image. Levels of brightness or contrast are from -100% to 100%, where 0
means no brightness/contrast is applied.

Hue/Saturation

The Hue/Saturation control applies only to color photo images. Hue is the aspect of
color that distinguishes one color from another (red from green from blue). In the
RGB color mode, hue can be distinguished by its position in the color bar.
Saturation, on the other hand, is the intensity of a hue (deep red vs. a lighter red).
This tool lets you adjust the hue or saturation of a color. To change the hue of an
image, move the slider to its new color position in the Hue slide bar. To change the
saturation, drag on the Saturation slide bar. Dragging the slider to the left decreases
saturation; dragging it to the right increases saturation. Beware of increasing
saturation too much, as it creates artificial-looking, overly bright colors.
