Method
This Node applies a Colour Look Up Table to the Image.
Colour Look Up Tables (LUTs) are a method of transforming the colours of an image. They are used extensively in colour grading in post production. Notch supports the standard 3D LUT format of .cube, exported by the vast majority of colour grading packages.
