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?
