Sometimes, when I scan negatives, then need to rotate them before importing them to Photos, the thumbnail in is the wrong orientation (but, when opened, the photo is orientated correctly). In Aperture it used to be possible to regenerate the thumbnail for an image. Is there a way to do that in MacOS Photos (6.0 - Big Sur).

Hi - Select them all. Then from the image menu, rotate clockwise, then rotate anti clockwise. Does that work?
You could also try auto enhance followed by (if you wish) revert to original. But this will undo any edits you might have applied.

It’s interesting. Rotate and rotate back seems to work some of the time, but not always (even going right round the clock flips back to the wrong orientation on the fourth click).
Auto-enhance and off again is an interesting idea - I will try it (they are all freshly imported - if I edit them the problem goes away).
I also think I should pay more attention to how I am actually correcting the orientation before importing to see what causes the problems - or maybe I should try not to do that but correct them after import (I think it’s SilverFast that sometimes isn’t exporting scans in the right orientation but I could be fixing them in Preview or in Finder).
If my further testing reveals anything I will post back here (next time I scan a film - I think I’ve fixed them all for now).
Thanks for all the suggestions!
Try to add a tiny adjustment, after rotating the image. Then Photos should recreate the thumbnail.
Thanks — yes, that is a solution works!
But I was hoping for a way that would let me select all the images in a folder with the problem, and fix them in one go… any ideas?
I would do the rotating after import.
Some rotate software rotates the image, but doesn't rotate the thumbnail built into the image file. This would cause the problem you are seeing.
Is there any way to refresh the thumbnail image in Photos for Mac?
