I have many duplicates. In an effort to gain control I consolidated all my folders, albums etc from the Apple app ('Photos'), ran them through a duplicate software, kept the ones I wanted and then transferred to Lightroom.
From 'Library' I see all my pictures. There seems to be hundreds of duplicates even though I ran the duplicate software. Here's an example of what the filenames look like. _DSC0095.jpg, _DSC0095-2.jpg, _DSC0095-3.jpg etc.
I'm not sure if all three photos are the same or are they different edits of the same photo. In most cases they look identical, the metadata is the same and the histogram stays the same. In some cases the color saturation is slightly different.
My second question is: I delete photos and they keep reappearing. Is that because they were originally in so many different folders?
