P.S. I forgot to add that I am running Digikam 8.6.0.

I tried exporting a few photos from Photos on my Mac, using Image capture to import them, and using direct Apple iPhone 5 (Direct PTP). I have an iPhone 16 running iOS 18.3.2 and a MacBook Pro running MacOS 14.7.4. When exporting, whenever possible, I checked the boxes to include Title, Keywords, Caption info and Location. If I have edited photos, I want to keep those edits, so am exporting the photos as-is, not the unmodified original. I have two problems.

Is this a problem? Am I missing functionality or do I risk problems with importing if I use the Camera option directly in Digikam?

Digikam has permissions to full access to the Photos app. When I try to add a new collection my Photos library is grayed out. Would adding my Apple Photos library as a collection make it easier to move photos out of it into Digikam while preserving any edits and titles/captions/keywords/location information? If so, how do I add it as a collection?
