Hello, I'm sure this is probably very simple but I was hoping to pick someone's brain about it.
Say I have a picture / video of some mountains and a sky and I'd like to manipulate only those RGB values that are close to the general sky-blue color. Ideally (and I'm sure this is easy in Max) a settable range of color tolerance as well as where in the matrix pixels are or aren't affected. I know jit.chromakey will get the selection, but how might I manage the selected pixels? Perhaps that resulting matrix would be manipulated, then mixed back into the original? Guess I'm not sure how to manipulate, then re-mix back in so that the effect can be anything from subtle to extreme (generally most effects seem to be extreme).
Thanks for humoring me, it's probably rather noobish of a question, but I'd be interested to see what others have done with this.
