Re: ocio2icc - Can I Create An ICC Profile From An Existing 3dl/csp LUT?

Hey all,

This exact issue has been on my to do list for a long time. Previously I looked at spaceman icc (http://www.lightillusion.com/spaceman.htm) but never had enough time to get it working properly. I'd love to see this feature added to ocio. While we're on the issue, I'd love to get people's opinion on their photoshop-nuke workflow. I believe I heard Jeremy mention Sony brings their stuff in a neutral color space (in photoshop) rather than trying to match what nuke see's with a cubic lut applied. Is that true?
Ultimately I'm looking for a way to have a cubic lut that's being applied in nuke, affect my matte paintings in photoshop and it look identical.

Thanks,

- Gresham

Thanks!

That said, I was wondering if there was a way to create an ICC profile
directly from 3DL or CSP lut? I think it's possible, but it appears to be
somewhat constrained to the creation of a proper ocio config (which I'm
still learning how to build).
Currently, no.

Both ociobakelut and ocio2icc require an ocio profile. However, it
would be a pretty simple change to add the functionality to allow you
to specify a single lut (or luts) on the command-line instead.

I'll see if I can knock this feature off in the next few days.
