Gemini: The Duplicate Photo Finder for Mac
I am an avid (if amateur) photographer. As I travel a great deal, I end up taking hundreds of photos per trip. Obviously, I always intend to go through these and only find the best, deleting the rest. But I never seem to get around to it, and end up reuploading and saving mass amounts of photos over and over again, from one device to another. Which leads to a fair number of duplicates over time.
