Is there a tool that reasonably compares photos (which may not have identical names, and may or may not actually be identical) and sorts out the duplicates by quality? I have about a Tb of unsorted family photos straight from digital cameras, and I need to back them up, but I also need to conserve disk space, because of the fucking oligarchs. Also, what would be the best storage method/medium for reliable long-term storage? #photography #beginnerQuestions
