Thanks a lot for your help,
the tutorial is very good(Premiere or After Effects not really matter, I’m looking for a solution in one of the 2) however it clearly begins with a video that, sorry for the silly comparation, has already a “red channel”, reds are hidden due to a heavy cast and colors unbalance, usually with underwater media the matter is cause to much green or bue) and the video correction takes them out, balancing white and enphasizing the overall aperance.
May I’m looking for something that it can’t be simply done with videos, I’m asking here cause i’m a beginner, some experience with photos not at all with video.
Thanks a lot!
