Powerful, Smart, Fast

Some excellent, powerful features make this app stand above the rest:

1. You can adjust the similarity metric for the duplicate finding algorithm. So if you want to find all similar (but not identical) photos, this app will do it.
2. You can set preferences for auto-marking which duplicate photos to discard. For example, say you always want to discard resized (smaller) photos, or the older version of a photo, or the RAW version, or whatever. You set the preference, auto-mark them, and then discard.
3. Fast — it took about 1 minute to find 12,000 duplicate photos on my 2012 MBPro, and about 5 minutes to remove them
