Convertion from icc to 3dlut

[moha...@gmail.com]

Hi,
Is it possible to do icc to 3dlut conversion? I have some icc profiles simulating some kodak and fuji stock and i want it to load it into a grading application which doesn't support icc.

Thanks and regards

It's going to involve applying your ICC profile transformation to an image like spi_32_lattice_aces.exr (from the OCIO sample configurations) and then use ociolutimage to make a LUT from it.

But spi_32_lattice_aces.exr has the ACES LUT applied - it's the output image. I'm not sure how you get the raw input image for applying your transform.

If you're on After Effects, there's a free plug-in called LUT Buddy that does a similar thing.

Look at DisplayCalGui, it has 3d lut from icc profile capability. Keep in mind you need to know your destination and source space.

Thank you very much for the replies. Brendan Bolles, i will try your way. Andrew Hunter, The icc profile is basically an scanner profile which has Kodak positive print profile in it. DisplayCalGui wouldn't convert this profile and gives me some error.
