I have been doing some searching around on the internet for something that does the equivelent of the colorX node in Shake. For those who have not used it before it allows you to enter formulas that can effect individual channel values based on the math you place in. You can link it to values from a light or a null as well as using all your normal math operators to adjust the original colour values. The kind of arithmatic I want to apply to these colour channels is not something I am going to be able to create with the tools under Channel menu in effects :-( .
Is there a plugin available that lets you do what im asking (or something I have missed :-P )? or is it something that can be achieved now with scripting? Perhaps if it can be done with scripting maybe someone might throw me a line or two on some literature to the basic techniques or a tutorial out there.
