An excellent solution to a challenging problem

Pretty great! The app matches photos based on more than just the file name, finding photos that are identical but stored in different sizes/resolutions and/or with different names. It even finds photos that are very similar but not identical, yet it doesn’t over-do this with a lot of irrelevant matches. For example, it found photos of people at a dinner table and grouped as potential duplicates several shots that were taken seconds apart, nearly the same but not identical. Despite this seemingly-error-prone ability, out of ~5,000 photos and ~600 groups of possible duplicates all have been reasonable for consideration as dupes.

Images are displayed large-enough and clear-enough (on a 15” Macbook Retina) to make many decisions based on appearance alone (such as photos which differ only in the filters applied to them). Any photo can be double-clicked for a fuller-sized view of it, and any photo can be clicked to see the full metadata for it so it’s easy to click among proposed dupes and decide which one(s) to keep. Click check on the ones to trash and move on… a bulk-delete awaits at the end which concludes with a satisfying summary of # of files deleted and disk space cleared to reward your effort. (It would be nice if this was reported on a running basis, showing growing # of dupes selected for deletion and total disk space as the dupes are being selected.) Nice app!
