Fantastic

This is a very nicely crafted application. It’s fast, clean, simple, and easy to use, with a beautiful interface. I especially like the preview pane to look at duplicate photos and feel satisfied that they are indeed identical. The only improvement, for me, would be the addition of any extra info about the files that might be useful. A duplicate photo, for example, could display its dimensions and resolution, along with the file size that is already being displayed. Even without however, this app is excellent.
