Have you checked file extensions? You might have your camera set in the RAW+JPEG storing mode, producing both .JPG and .NEF file for each shot, showing the same thumbnail for both of them. Also many image viewers would show both of them. Solution: Turn off RAW+JPEG mode and use JPEG only mode. Check page 85 of the Nikon D7000 manual - Image Recording ...

A number of programs can find duplicates based on image contents. Some asset management apps will do it and there are also dedicated programs. If you Google 'detect duplicate images' you'll see quite a few options. See which ones are available for your platform. Another solution is to simply import the files with the 'ignore duplicate option'. Picasa, which ...

If the images actually are duplicates then the additional data is most likely to be metadata which has been added at some point. In other words the files have been modified, although the picture itself has not been touched. Most likely an automated function in your photo viewing/management software has done it. For example facial recognition which is ...

ImageMagick to the rescue. I think the first step to any solution is to reduce the size of your collection. If you want to compare the photos by its content, especially when some are slightly modified versions of one another, a very good start is to reduce them to thumbnails and then compare the thumbnails. This is particular helpful when you want to find ...

Picasa has a duplicate file finder but it's hard to tell what you are looking at: Run Picasa; click Tools > Experimental > Show Duplicate Files. It works but be careful about what you are deleting.

There is a little utility called "fdupes" that may do what you wish? There is also another utility called "fslint" that you might want to try out too. (This one has a GUI).

If the duplicates are virtual copies, you can use a library filter to view only the copies. Then select the results and delete.

Hashes are actually the key to doing this and getting it right. If you're up to getting your hands a little dirty, this would be an easy effort as a shell script: Generate a list of hashes of every file in your master archive. Call this list "MA ("master archive"). Generate a two-field list of hashes and paths to every file in your other archives. Cal ...

Whilst I can't recommend this personally, I did stumble across this Lightroom Plugin the other day: http://www.lightroom-plugins.com/DupesIndex.php

My go-to method of finding exact dupes is this command line on windows with cygwin or linux. find /path/to/files/ -name "*.file-extension" -exec md5sum -b {} \; |sort|uniq -w 32 -c|sort -n The bottom of the list will show the dupe md5 hashed with the path to the first instance of the file. You can find all copies of that file with: find /path/to/files/ ...

For Linux, try FSlint. It's a bit slow, but it will definitely find duplicates.
