In order to understand color managment it bit better, I have been digging
into some of the profiles on my system.
I see that the default color negative input profile for my Imacon Flextight
Photo scanner has RGB XYZ tags and TRC tags, but it also contains matrix
based A2B tags. What is the reason for this redundancy, and how does
software, e.g. scanner software and PhotoShop, use such a profile in
practise.
I have been told that scanner profile conversion is always relative
colorimetric, but I find an A2B0 tag and the header entry gives "perceptual"
as the rendering intent.
Thanks,
Tim
