- reversable, but not 1D color transforms in config.ocio
Re: reversable, but not 1D color transforms in config.ocio
Doesn't really answer your question (sorry) but.... On Transformers the director wanted sharper cg robots! so we had a sharpen shootout. The joint winners were either LAB or Log, unshapen masks.i.e. the difference between artifacts when filtering it in L*AB or log was very minimal. It might be easier for your PS artists to use a lut rather than a RGB>LAB transform?

No assurances expressed or implied. Seems the values are darn close to Lindbloom's, which may account for a different value for Illuminant C adaptation via Bradford.

The conversion from XYZ to CIELab can be done with matrices and 1d-LUTs, so you should be able to do the forward and reverse quite exactly with the existing machinery and without resorting to 3d-LUTs.
(Of course CIELab is only appropriate for display-referred colors, but that is a separate issue.)
