OCIO colour space transform
Last updated
OCIO colour space transform is a Colour effect.
What it does
Section titled “What it does”Converts the layer’s pixels from one colour space of the project’s OCIO config to another. The lists come from the config chosen in File ▸ Project settings ▸ Colour. A space left at Working space is the space Lumit composites in, so setting only Output colour space is an output transform and setting only Input colour space is an input transform.
