A lot depends on where and when you want to find the duplicates. A great little though a bit old (last update 2013) is Free Duplicate Photo Finder by Free Pictures Solutions. It performs a dupe check looking at the pictures themselves, not just the file name and size. It then presents you with a percentage of similarity and the pictures side by side. So you can judge if you want to keep it or dump it. This program is for windows. Google's Picassa will also perform a duplicate check but only on import. It is a great management and review tool though.
There are also duplicate detection tools for the smartphone itself. While I didn't dig into the Apple Iphone choices I did find search through the Android phone choices. There are a lot and there are just as many reviews for them out there.
For more than several years I have taken pictures with my iPhone and also my camera. Periodically I transfer those pictures to the hard drive on my computer. I now have many thousands of pictures from all over the world, family and friends, spanning four years or so. Unfortunately at some rare times, I did not delete the original pictures on my phone or camera upon copying them to the hard drive so there are some duplicates. Even worse, I simply imported each group of pictures into a separate file folder labeled with the date of the group import. Each specific picture then had the import date and a number as the picture name. Some pictures are fuzzy and should be thrown out. The above presents a number of challenges:...
-- Is there a software program that will detect duplicate pictures even though the label is different?
-- Is there a software program that will easily allow me to view the pictures quickly one by one so that I can label them accordingly?
-- What is the best system for labeling photographs? I would think the label might include date, person, scenario, ?? or do file folders appropriately labeled also come into the picture? And what would the label for the pictures and file folders look like?
Help would be greatly appreciated.
