Not quite sure how it is related to Lightroom, when the issue is the export from photos app.
Or have you imported the exported files into Lightroom, and in Lightroom catalog you have multiple copies of same files and similar other issues?
You're probably right - it may be more of an iPhoto issue. It seemed as though it would be an issues that others converting from iPhoto to LR would experience, given that there have been many questions posed here about how to do that. My understanding is that you have to export photos from iPhoto to an external (as in, outside iPhoto) folder so that LR would recognize that folder (it doesn't recognize iPhoto folders) and be able to import into a LR catalog. But you're correct - the problem is that when I exported from iPhoto to that external folder, it created all these multiples, even before I opened the folder in LR to decide what to import.
That being said, if I could determine within LR which of the multiples were the largest size (i.e presumably best resolution) files, it would probably be faster to identify unwanted multiples and delete them from the disk. Any ideas?
Thanks so much! Maybe I'll post this question on the Apple website for iPhoto users.
Yes indeed you should post in Apple forums,
FYI - there is no way of figuring out duplicates in LR automatically, one has to go through the images and look for duplicate ones.
You are welcome.
