- Contrast
-
Set the spinner between 0 and 1.0. This compresses or expands the latitude between maximum black and maximum white by creating a 16-bit look-up table for any given gray value in the image. The computation of the gray value depends on whether you select Absolute or Derived.
- Brightness
-
Set the spinner between 0 and 1.0. This increases or decreases all color components (red, green, and blue).
- Absolute/Derived
-
Determines the computation of the gray value for Contrast. Absolute uses the highest value of any of the color components. Derived uses an average of the three color components.
