I have collected all of my photographs onto one hard drive. I'm looking for software that runs on Mountain Lion to assist in finding similar photos so I can review and eliminate redundant files.
My picture store is currently 2 TB, so batch and/or efficient software would be ideal. I know for certain that there are a lot of duplicates, and there are lots of programs out there which can find exact duplicates.
What I am looking for is something which will find:
- pictures which are identical except for rotation
- pictures which are identical except for size (i.e. an original vs a thumbnail from iPhoto, or an original vs a downsized version for the web, etc)
- pictures which are similar
I assume #1 is possible, but I am not sure about #2 or #3. What software can do any or all of these tasks?

The best that I could find and have used is Duplicate Annihilator, which works with iPhoto, and is upgraded for 10.8. You can download and do a run and hopefully get rid and clean your folders the first time through. For what you need you might need a few passes to get the obvious dups, then find the harder to get ones.

I am not exactly sure it will find your #2 and #3 right out of the gate, but since photos are marked with unique timestamps and other meta data, it should find them even if rotated. The similar part is a bit harder as the criteria for similar could be many things. Run through a few times first checking my filename, then maybe dimensions, creation date, etc.
