For more information on using the Gradient editor, see Using the Gradient Editor.
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.
HUD Controls
The HUD contains the following controls: Gradient, Offset, Repeats, Repeat Method, and
Map Channel.
Hue/Saturation
This filter 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.
Original image HSV Adjust filter applied (low saturation goes to
grayscale)
Parameters in the Inspector
Hue: Sets the angle of adjustment used to set the zero point of the color wheel.
