Re: photoshop 6 beta?

Thanks for the details. That's great to know.   The forums you point at are fun reads too. ;)

I'm wondering if 3d lut adjustment layers are pulled internally into the .psd file, or are 'live' external references?  (or maybe both options exist, similar to icc profiles?)

It's neat that they got .look file support it there.  (And it makes sense given Adobe's acqusition of Iridas).  Probably a good ocio format to add in the near term.

I'll have to download the beta. I'm also interested in confirming our lut application matches theirs...

Installed it today. After like 20 minutes of looking around, found where the LUT's are loaded… You can add a "Color Lookup" adjustment layer:

..or "Image > Adjustments > Color Lookup" and bake it into a layer.

Couldn't see any way to apply it purely as a viewing LUT, which is a shame (adjustment layers make picking colours tedious, and you have to disable it before exporting), but.. I could very well be missing something.

Not sure about a full list of formats, but the "Adobe Photoshop CS6/Presets/3DLUTs/" directory contains a bunch of .3dl files (two variants, one with "MESH" line, one without), .look files (IRIDAS format), and a .cube file

Think this is a representative sampling of the included LUT's:

It can also apply "Device Link" and "Abstract" ICC profiles

About the only mention I could find of the 3D LUT support (aside from copying-and-pastes of the feature-list) was
In my searching, I also came across this amusing thread (well, "amusing" in a frown-inducting way)
Reminds me of the Photoshop vs OpenEXR alpha/premult debate (oh, it's the same Adobe employee, which makes it a bit less worrying :P)

Anyway, hardly OCIO integration, but seems like a step forward. I'll play about more with it later!

Has anyone tried the photoshop 6 beta yet?  One of the line items is '3dlut adjustment', and I was curious what this meant. Couldn't find the docs online (yet).  Maybe you can now select a 3dlut from disk, and bake it into an image? I'm curious what formats they support...
