I have started to import my old Media Pro photos from the early digital camera ages and also slide scans.

Unfortunately not all are rotated correctly, maybe because Peakto ignored this information from the Media Pro catalog, or it wasn't stored / recorded in the image..

Did I missed this function, or is it just not there?

Maybe AI can help to rotate them correctly, depending on the motive.

I wonder a bit about the Smart Album settings for "EXIF Orientation"?

I would expect to choose from portrait/landscape aka vertical/horizontal. "Top Left, Bottom right", etc. is a bit confusing.
