CDL Transform is not sufficient for ACES specification.

Open KevinJW opened this issue 9 years ago • 1 comments

there is an issue when using OCIO based CDL transforms in ACEScc space.

As described by the ACEScc specification http://www.oscars.org/science-technology/aces/aces-documentation appendix B, values below 0 are supposed to be passed as-is through the power, however the current implementation clamps the output to 0.

Note this is not a bug per se as the ASC CDL spec says to clamp, the ACEScc spec says not to.

I believe this is now resolved by use of the CDL Style parameter set to not clamp.
