Color Space Transform (CST)

A Color Space Transform (CST) is an OpenFX node built into Resolve that converts an image from one color space and gamma to another. Tell it the input (what the camera shot, e.g. S-Log3 / S-Gamut3.Cine) and the output (e.g. Rec.709 / Gamma 2.4), and it does the conversion mathematically, on its own node early in your tree — the recommended, tunable way to normalize log.

First used in: 1.5 · Log, LUTs & normalization
