RGB Mixer Examples
This is an extremely flexible and open-ended tool, and you’re probably already getting a sense of the
creative possibilities. However, here are a couple of more utilitarian uses of the RGB mixer that are a bit
less obvious.
Example 1: Increasing Saturation While Reducing Cross-Talk
In this first example, we’ll see a creative use of the RGB Mixer that uses a technique similar to one used
by telecine artists, to “purify” individual color channels, and raise image saturation in a different way then
when using the Saturation parameter.
To raise saturation while eliminating color channel crosstalk:
1. To isolate this correction from the other operations in your node tree, create a new
serial node.
2. Open the RGB Mixer tab in the Color page.
3. In each of the three control groups (Red, Green, and Blue), boost the value of the
primary color parameter for that group, while reducing the value of the other two color
parameters by half.
For example, in the Red control group, raise the Red parameter to 148, while lowering
the Green and Blue parameters to -24 each. Do the same for the Green control group,
raising Green while lowering Red and Blue, and the Blue control group, raising Blue
while lowering Red and Green.
