I've been moving photos from the Photos app on my Mac to lightroom by first exporting from Apple Photos and then importing to Lightroom. All seemed fine. Today, I tried to use some of those photos to make a book in Lightroom. When I went to the book module, the photos I imported from the Photos app where greyed out. Went back to the library module and noticed they weren't actually photos but were short, 2 second videos. I'm guessing that this was so-called "live view" on my iPhone.
How can I fix this? I select to export "unmodified original" from the Photos app. I thought this would give me the highest quality photo. Should I export to a JPG? Seems I'd lose some image quality.
