When using Photo AI as aLightRoom plugin when exporting Olympus OM-1 .orf back to LR the result is quite yellowish cast.

I just processed the file on my computer using v1.4.3 and the output was the same color as the original.

Do you have antivirus or any edits on the original image that could be affecting the output?

did You utilize PhotoAI as a LightRoom plug in? It’s then when it happens.
I’m going to a short photo session today and I can try to reproduce the problem with new files then. As I can recall it makes np difference wether there’s any edits or not.
I have made a default camera profile in LightRoom.
I have an antivirus software. How could thta have any effect on the process?

FYI I uppdated PhotoAi to 1.4.3 and resetted all settings if the photo I exported from LR to PAI. It didn’t make any difference.

The antivirus or some security application could be preventing Topaz Photo AI from writing the correct metadata to the output file which is causing color shift.

Please try changing where the original file is stored and disabling the antivirus to see if that changes the behavior.

I have the same issue, only on a Windows laptop not a Mac. Keen to hear the outcome (not keen to disable anti-virus software!)

Yes, disabling antivirus is a bad option.

Did you check if it changed the behavior? You may only need to add Topaz Photo AI to the exception/safelist to get it working instead of disabling everything.

What is your workflow? Is the color shifting in Topaz Photo AI or on output?

On MacOS the antivirus sotware settings are a bit different which means tha there’s no individual settings for each application (at least in the case of my antivirus software). That means that I’d have to uninstall the antivirus software and that’s something I dont’t want to do.

I export the raw file from LightRoom to PhotoAI as a plugin. FIle->Plugin Extras-> Topaz PhotoAI. The color shift can be seen right after LightRoom has build the preview of the .dng. The color shift is also on the output .jpg, .TIFF etc. Even syncing the settings in LightRoom from original raw to PhotoAI .dng doesn’t correct the color shift. I have resetted the original raw files settings before exporting to PhotoAI but that doesn’t help either.

In MacOS System Settings > Privacy & Security > Full Disk Access, enable full disk access for Topaz Photo AI and Adobe Lightroom Classic if it is not enabled already.

Let me know if that changes the behavior.

Did that, but unfortunately no change.

I uppgraded to version 1.5.0 and handled three photos with it today. Two were spot on and one was nearly ok with only a slight yellowish cast…

We haven’t changed any of the file handling so I’m not sure what the cause is.

Is it consistently shifting the color still? Hopefully it’s better now.

No it’s not constant. The shift appears randomly and when it appears syncing with the original in LightRoom some times corrects the shift and sometimes it doen’t. The shift can of course be adjusted manually but it is not supposed to be like that isn’t it?

it should be consistently returning the image with the correct colors.

The inconsistency is the most confusing part. Is there something in particular that seems to separate the images with the yellow cast from the ones that work properly?
