5 years ago, repeating [history](https://forum.corona-renderer.com/ Correct 32bit workflow between Corona and Photoshop (ArionFX) )
An idea, you can use VFB+, it has support for ICC profiles, and the best thing is it’s free.
It won’t work with IR but it will take your Corona VFB output on render end and display it the way you would see it in Photoshop when the same profile is specified.
The problem won’t be solved unless Max finally has some sort of color management. Autodesk is going for OCIO which recently got support for ICC, but who knows how long that will take to be incorporated into Max.
Corona could also add support for ICC profiles just like VFB+.
According to Adobe Bridge metadata panel:
Exporting an .EXR from the Corona Renderer VFB (3ds Max) produces a sRGB IEC61966-2.1 (linear) image.
Exporting a .PNG from the Corona Renderer VFB (3ds Max) produces an untagged image.
- The .PNG image appears identical to VFB when viewed in Chrome.
- The .PNG image appears identical to VFB when uploaded to Artstation (Chrome).
- The .PNG image appears identical to VFB when viewed in Adobe Bridge full screen preview (spacebar).
- The .PNG image appears identical to VFB when viewed in Image Glass.
So, Photoshop is mediating the appearance of the .PNG at some point, or Windows is failing to communicate color information - or successfully communicating wrong color information - to Photoshop to cause this behavior(?).
I assumed the ‘convert to sRGB’ option was not checked in the Photoshop Export Preferences, but enabling that option does not change the behavior.
After testing so many permutations of color settings between Windows, Photoshop, etc., it appears that Photoshop is applying my monitor profile to the untagged image, which is causing the color change (darkening / contrasting) on export.
The question is why is it doing this?
Is Windows color settings involved?
If anyone has any thoughts about why these settings might make sense or why they are utterly wrong, I’d be very interested to hear them.
I give up :- )
Your situation is not different to one the previous users asked. On previous page I outlined exact solution. It doesn’t feature monitor profile in Windows at all, I highlighted like 5 times in row that option is wrong. It’s not “working”. You only believe it does, but that was also explained.
This is not correct. Corona Rendered is not modulated by anything. Corona and 3dsMax fully ignore your Dell.icm, they are not color managed (“color-profile aware” in other words).
Right, as you’ve said several times before, it’s not “working” but it appears to produce a consistent image between applications.
It seems strange because I reviewed images produced this way on other devices - that have not been tampered with in color settings - and the images remained consistent, e.g. Dell laptop, Google Pixel.
Thanks Juraj. I set it up like this on a new computer and works really nicely.
There is now (since late 2021) alternative solution because of GitHub - ledoge/novideo_srgb: Calibrate monitors to sRGB or other color spaces on NVIDIA GPUs, based on EDID data or ICC profiles · GitHub
it’s small tool that superimposes color-profile on non-color managed application. It’s not perfect but it’s something.
But color-management is still needed on Autodesk & Corona side. I’ve heard rumor of something next year
Thanks. Yes. I saw this on another of your posts, but you mentioned possible conflicts and I rather stay away for now.
