Is it possible to use ocio to crest an icc profile that can fully define a color space with XYZ PCS like a classic srgb or adobe rgb profile? What getting at is that I've defined a device color

I don't have

Assuming that you have OCIO compiled, the command line tool "ociobakelut" should fill that need. ociobakelut --lut <your_lut.3dl> --format icc --description <description> <output_file.icc> There is an

Can you do one with it for me. I can pay

Thanks Brendan, the new beta worked without any errors. Cheers! ------------------------------- Simon Björk Compositor/TD +46 (0)70-2859503 www.bjorkvisuals.com 2017-02-13 18:01 GMT+01:00 Brendan

Yep, that's a bug! I've posted a new beta with a fix. Let me know if you find other problems.

Hi Brendan, I tried with a few configs (my custom, ACES and Nuke default). Here's some screenshots (nuke-default): https://www.dropbox.com/sh/16753ezhpozn9r6/AADnZy3uRl7WXgMdW8ZkoVSBa?dl=0 Best

Hey Simon, it's supposed to work. I think this is what we call a bug (you'll notice the plug-in is actually in beta). Which configuration and settings are you using? Brendan

This is great Brendan, thanks a lot! It will save lots of time. One thing though. How is the Display option supposed to work? When I try to use it I get the following error: Coul not complete the

Or maybe create some! ;) I've spent a fair amount of time making Photoshop do this stuff for a few different studios, and it's really a pain in the neck. After jumping through a bunch of hoops I have

Looks very interesting! Certainly will make a lot of headaches go away, I'll try and take a gander asap. And yes, we will be taking pull requests again.

Hey everyone, I've made an OCIO plug-in for Photoshop. There are download links in this blog post: http://fnordware.blogspot.com/2017/02/opencolorio-for-photoshop.html I've got the code in my GitHub

Cool, that's what I thought. Just making sure you hadn't snuck anything else in there I hadn't noticed! And yeah re: LAB space vs Log space for doing the actual sharpen --that's an interesting idea

> Troy, I was looking through your (amazing) example, and the only part that I didn't recognize was the matrix you used to go from RGB to XYZ based on srgb d65 primaries. I didn't do much other than

You all are my heros. I had gotten so caught up in the XYZ to LAB calculation that I didn't notice it could be reduced to a 1d LUT and simple matrix. Troy, I was looking through your (amazing)

Doesn't really answer your question (sorry) but.... On Transformers the director wanted sharper cg robots! so we had a sharpen shootout. The joint winners were either LAB or Log, unshapen masks.i.e.

Whilst stranded in an airport... https://gist.github.com/sobotka/97707cf481049fd3267d85510f30db1e No assurances expressed or implied. Seems the values are darn close to Lindbloom's, which may account

The conversion from XYZ to CIELab can be done with matrices and 1d-LUTs, so you should be able to do the forward and reverse quite exactly with the existing machinery and without resorting to

The shaper here would be a purely technological solution, simply helping out interpolation given that your input happens to be imagery. In your CTL, you would assume that you are being fed Log2 values

L* is inherently logarithmic, so perhaps you could use L* it's self as the shaper here. But I think the inherently negative a*b* values will make this effort futile, unless there is an alternative all
