The best deduplicator out there

This is the only photo deduplicator that I actually like, and I’ve tried a lot of them.

My photo situation was a mess. After merging 2 iphoto libraries and a lightroom library together, I found myself with duplicates of all kinds. I had full sized originals, and I had scaled down versions that came from photostream or facebook. I had JPG, NEF and DNG versions of the same pictures. I had thumbnails that had been imported by mistake. I had photos with identical content, but different metadata. When I was done, I had an iPhoto library with 44,000 photos and thousands of duplicates.

Every other app I tried fell down somewhere. Some werent flexible enough to dedup across multiple file sizes and images formats. Some deduped fairly well, but would pick/delete the wrong copy of the photo. Most were cumbersome to use. All were slow.

Then I found PhotoSweeper, and it just worked. Its faster than anything else Ive tried, its easy to get started with and it has a great UI for browsing/tweaking the results. It removed 8,000 duplicates and saved almost 100gb of space. Im a fan.
