Applies OpenColorIO “looks” to an image.
A ‘look’ is a named color transform, intended to modify the look of an image in a ‘creative’ manner (as opposed to a colorspace definition which tends to be technically/mathematically defined).
Examples of looks may be a neutral grade, to be applied to film scans prior to VFX work, or a per-shot DI grade decided on by the director, to be applied just before the viewing transform.
OCIOLooks must be predefined in the OpenColorIO configuration before usage, often reference per-shot/sequence LUTs/CCs and are applied in scene linear colorspace.
See the look plug for further syntax details.
See opencolorio.org for look configuration customization examples.
