Cropping changes brightness/colors

Simply cropping some images changes their brightness and colors quite dramatically.

I am currently using version 19.1.6 of Photoshop on macOS 10.12.6.

In this video you can see me crop an image a little bit and then undo and redo the crop to see the effect:

What image mode are you using in the file you have open in the video, and what image mode does the photo smart object (bottom layer in Layers Panel) use?
Image > Mode > ?

Which filter is being used as a smart filter on the photo smart object?


Try your cropping test again with all your adjustment layers hidden.
If cropping doesn't cause brightness to change, unhide one adjustment layer at a time and re-test.

It's in the 16bit RGB mode (99% of my work is done that way).

The smart object is the Camera RAW image. I probably should have mentioned this: I always open my RAW files as Smart Objects in Photoshop, so that I have access to the settings later, if need be.

Cropping with all the adjustment layers hidden or deleted causes the same change in brightness. The same is true for other images.

I think I actually found the reason for the problem: Cropping causes the Process version of the RAW file to change from whatever it was before to "Version 4 (Current)"! That's why this problem only seems to affect older files.

This is clearly a bug. Is there another way I can report this to Adobe apart from this forum?

Wow, that's interesting.

Best way I know of to get a real report submitted is to get the attention of an Adobe rep here, and trust them to relay the info to the proper team.
Jeffrey Tranberry may be your guy.

Thanks! Do you know if it is possible to tag people in this forum?

I noticed another detail: Cropping causes the Process Version of the embedded RAW file to change from what it was before to "Version 4 (Current)". But if I then select another Process Version and then "Version 4 (Current)" again, the colors are different again (unlike the original and unlike the version after the crop).

EDIT: It gets weirder. When I open the RAW Smart Object and change the Process Version to the current one and adjust the settings and click OK the colors are different than what they used to be but at least now they should stay the same, right? But they don't. Cropping now also causes them to change again. This makes it impossible to work on these files for me.

Sounds like a nightmare. You'll have to downgrade if you uninstalled your previous Photoshop installation. Ouch.

Nope, I don't really know how to get anyone's attention around here. You just have to cross your fingers.

Update: I just updated to the latest version of Photoshop (20.0.1) and the problem is still the same.
