Hi Justin,
I strongly believe that you should provide support for dcp profiles here, and NOT do what Adobe Camera Raw does, which is applying an automatic lightness correction, white balance and an S-shaped curve.
Capture One has the problem that they use 2 profiles, the first one is like a dip profile, but the user has no control over it. As a secondary color transformation one can use an ICC profile which you can create yourself, but it is a bit tedious. The users would rather see and control only ONE color transformation.
Is there any way we can talk about this in more detail on the telephone?
Thanks, Francis
