Using Limit Effect Controls in the Color Corrector
and Color Corrector 3-Way Filters
The Limit Effect controls are a group of controls in the Color Corrector and Color
Corrector 3-way filters that let you key a specific color and apply color correction to
just the areas of the picture that you’ve keyed on.
For example, suppose you have a scene with people wearing different-colored shirts.
After the shoot, you decide you want to change the color of one of the actor’s shirts
that’s now yellow. Assuming there is nothing else in the picture with the same values
of yellow, you can use the Limit Effect controls to selectively make this change.
