If you have a LUT-based input profile, the input>PCS part of the

user requests abscol, because the working space profiles are matrix
profiles, and matrix profiles contain only one rendering intent. In
theory, you can build matrix profiles using any rendering intent,
but the Photoshop WS profiles are all relcol.
I have been chewing on this for a week,
this is what I'm trying to swallow:
It sounds like we are saying that ONE
profiles and CMM-based conversion actually makes TWO
applications of rendering intent:
one from source to PCS, and
one from PCS to target.
True?
I can't swear to every CMS implementation out there, but that's how
Photoshop 6 and 7, and all the other Adobe color-managed apps, work.
