I just came across this very good point of view from one of the members here.(Thanks To You For Your 2cents)
And I like it so much I thought maybe this topic could be explore more for either people just starting to get into compositing or need a refresher course.
So when all of you Pros have a chance please leave your P.O.V from what you have learned.
What are main concepts of compositing that one should learn regardless of what compositing app one choose to use?
Thank You All
P.S. I will also post this at CompClub
