There are no controls for this filter in the Dashboard.
Levels
This filter provides controls to remap the white and black points of an image, along with
a Gamma control to adjust the midtones, all at once. A histogram provides an analysis of
the image that you can use to help you judge the adjustments you want to make.
A powerful option within this filter is the ability to make independent adjustments to
the red, green, blue, and alpha channels of an object.
Parameters in the Inspector
Histogram: An analysis of the object. By default, the RGB channels are selected. A pop-up
menu can be used to select red, green, blue, or alpha channels individually for viewing.
For each channel parameter (RGB, Red, Green, Blue, Alpha, and Gamma):
Black In: Sets the In point for black, below which values are considered black. The
parameter ranges from 0 to 1.
Black Out: Sets the Out point for black, above which values are not considered black.
White In: Sets the In point for white, below which values are considered white.
White Out: Sets the Out point for white, above which values are not considered white.
Gamma: Sets the amount of gamma correction. This parameter ranges from 0 to 5.00.
