Hello Affinity,
I am trying to convert a 32 bit image - rendered with Redshift/Houdini - into an 8 or 16 bit image with the proper OCIO/ACEs transformation baked into the ICC profile.
At the moment, I am forced to rely in the ICC profile instead of ACEs when doing this transformation to 8 or 16 bit.
This is, however, an incorrect workflow because of the fact that it will clip highlights, does not account for the change in ACEs CG primaries which results in desaturation, and is generally not as accurate as what is implemented with ACEs due to the order of operations during the transformation.
I am aware that there is a suggested fix for this by converting to 8/16 and then applying a 2.2 gamma curve reduction once the sRGB ICC has been applied via a live filter layer.
However, as mentioned above, I am still left with clipped highlights and desaturation.
Is there a way to apply an ICC profile which does nothing to the image? Or, ideally, a way to convert to 8/16 bit without altering the pixel data in any way.
Thanks in advance,
- Tyler
