Pre-Divide/Post-Multiply
Selecting this checkbox causes the image pixel values to be divided by the Alpha values prior
to the color correction, and then re-multiplied by the Alpha value after the correction. This helps
when attempting to color correct images with premultiplied Alpha channels.
Saturation Tab
This Setting tab includes controls for the intensity of the colors in the individual RGB channels.
RGB Saturation
When adjusting an individual channel, a value of 0.0 strips out all that channel’s color. Values
greater than one intensify the color in the scene, pushing it toward the primary color.
Balance Tab
This tab in the Color Gain node offers controls for adjusting the overall balance of a color
channel. Independent color and brightness controls are offered for the High, Mid, and Dark
ranges of the image.
Colors are grouped into opposing pairs from the two dominant color spaces. Red values can be
pushed toward Cyan, Green values toward Magenta and Blue toward Yellow. Brightness can be
raised or lowered for each of the channels.
CMY Brightness Highs/Mids/Darks
By default, the Balance sliders can be adjusted by -1 to +1, but values outside this range can be
entered manually to increase the effect. A value of 0.0 for any slider indicates no change to the
image channel. Positive and negative values indicate that the balance of the image channel has
been pushed toward one color or the other in the pair.
