| Color Spill node | |||||
| The *Color Spill* node reduces one of the RGB channels so that it is not greater | |||||
| than any of the others. | |||||
| This is common when compositing images that were shot in front of a green or blue screen. | |||||
| In some cases, if the foreground object is reflective, it will show the green or blue color; | |||||
| that color has "spilled" onto the foreground object. If there is light from the side or back, | |||||
| and the foreground actor is wearing white, it is possible to get "spill" green (or blue) | |||||
| light from the background onto the foreground objects, | |||||
| coloring them with a tinge of green or blue. To remove the green (or blue) light, | |||||
| you use this fancy node. | |||||
| There is one input to this node, the *Image* to be processed. | |||||
| The *Enhance* slider allows you to reduce the selected channel's input to the image | |||||
| greater than the color spill algorithm normally allows. | |||||
| This is useful for exceptionally high amounts of color spill. | |||||
| The outputs of this node are the image with the corrected channels. | |||||
