•
Offset: Sets an amount, in degrees, that the color wheel is offset to determine color application.
Values start at 0 degrees.
•
Repeats: Sets the number of times the gradient repeats over the course of its range.
•
Repeat Method: Sets the method by which the gradient is mapped when repeating. Values
can be set to Mirror (default) or Wrap. This parameter affects the filter when Repeats is set to a
number greater than 1.
•
Map Channel: Sets the channel used to determine how the image is colorized. Values can be
selected from the following: Luminance (default), Red, Green, Blue, or Alpha.
•
Mix: Sets the percentage of the original image to be blended with the color-corrected image.
Hue/Saturation
Provides controls to adjust Hue, Saturation, and Value levels in an image. The Hue control is an
angular representation of the color values in an image. By rotating the Hue angle, you uniformly
remap the colors throughout an image, similar to the effect of turning the hue or phase knob of
a broadcast monitor.
The Saturation slider controls the intensity of color in an image, with a high value resulting in
vivid color, and a low value resulting in a grayscale image with no color at all. The Value slider
adjusts the overall brightness or darkness of all colors in an image, including the blacks and
whites in a desaturated image.

Parameters in the Inspector
•
Hue: Sets the angle of adjustment used to set the zero point of the color wheel.
•
Saturation: Sets the color saturation of the object, ranging from –1.0 (no color information) to
0.0 (unadjusted color) to 3.0.
•
Value: Sets the intensity adjustment applied to the object.
•
Mix: Sets the percentage of the original image to be blended with the color-corrected image.
Levels
Provides controls to remap the white and black points of an image, with a Gamma control to
adjust midtones, all at once. A histogram provides an analysis of the image to help you judge the
adjustments to make.
A powerful option in this filter is the ability to make independent adjustments to the red, green,
blue, and alpha channels of an object.
