LR colour shift issue PS-LR

[akapaddy]

Okay so before I start, I have searched for this issue in the forums, I found this thread which appears to be the same issue but the fix - resetting the PS preferences - has not fixed the issue for me.

I'm using a Mac Studio with the Studio Display, both LR and PS are up to date.

Relevant LR and PS settings are thus:

So my RAW files look fine in LR.  Export to PS, edit, save as TIFF.  Now the file in LR looks like it has the wrong colour profile assigned to it (see screenshots) - and if I reopen the same file by re-exporting to PS, it retains this mismatched colour information.

I'd appreciate any insight, thanks.

Did you check the color profile after you reopened the file in Photoshop? If it is not ProPhotoRGB, then this is indeed the same problem. A workaround would be to assign ProPhotoRGB again, but that is obviously just a work around. Maybe you should delete the Photoshop preferences rather than use the key combo to reset them. The location is Users/[user name]/Library/Preferences/Adobe Photoshop [version] Settings

If that does not work, then maybe resetting the Lightroom Classic preferences does.

This is the second case in one day. The other user was also on Mac, let's see if Windows cases come in.

Yes, the problem is very clearly that the ProPhoto profile is stripped somewhere - just like a very similar bug we had some months ago.

It's beginning to feel like a bona fide new bug.

Can you check in Photoshop's  Save As dialogue that 'Color : ICC Profile : Pro Photo'  is checked.

Thank you for the responses to date.

I think I have discovered the issue.

My Mac Studio has an Apple Silicon chip (M1 Max).  Both LR & PS installed versions are for Apple Silicon.   However I recently had an issue whereby 'Extensions' was not available in PS.  Internet research revealed that to enable Extensions (Legacy) it was necessary to launch Photoshop using Rosetta (simply a matter of right-click on Adobe Photoshop 2023 in Applications Folder, Get Info, Tick the box, Relaunch).   I had done this for PS but not for LR (as I was having no issues with LR to this point).

I remembered this recent change and decided to follow the same procedure for LR - launching it with Rosetta.   This appears to have resolved the problem!  The image file above still has a 'bad' profile baked in, but other images processed since I made this change are all fine.  I can save the Tiff file in PS, reopen in LR, and there is no colour shift.

Maybe this should have been an obvious fix to some, but not to me.  I am posting the details hoping they might be of use to other Mac users running systens with Silicon chips.  My advice - if using Rosetta for any reason in either LR or PS, make sure that both are being launched with it, so they can 'play nice' with each other.

Excellent, thanks for reporting back!

@D Fosse ,

Thanks for the info. I did not have any problems on my iMac which shows in my signature info.

The other thread I created relates to my Windows laptop and I have indicated, there in an earlier post, that my issues have been resolved.

Ah, OK, then I misunderstood. My bad.
