PreMults are one of the most misunderstood elements of compositing. This lesson is to demystify this concept and allow it to move into your nomenclature.
Channel nodes and their operations is the cornerstone to understanding NUKE and the core of compositing. No other nodes are so useful and simultaneously the most misunderstood. We will peel back the veneer and demystify the way NUKE operates on channels and understand how, why, and when to implement them to create bolder work with more fluidity and polish.
What Will I Learn?
You will learn the fundamentals of why a premult node an unpremult are needed in compositing. This concept is fundamental to good edges and better work.
