Re-saving a file with an updated jpg preview (or the whole file if it was a jpg) looks much the same but can be quite different to a comparison tool Minor editing such as straightening a horizon drastically changes an image but we "see" the content as being mostly unchanged (just rotated). changing white balance from one preset to another changing the colorspace setting without changing the pixels changing the dpi value without changing the pixels
Any luck and advice you can share?įinding duplicate photos is complex, unless they are exact matches byte-for-byte.Ī major issue is that too much software can add, delete or change metadata and make the file different - even though the image data is the same. Jim, I'm in the same boat as you.and need to do the same. Or try Duplicate Photo Cleaner, which can find exact matches easily and also similar pictures with user-specified degrees of similarity (and success).Įasy Duplicate Finder will find exact matches of any files anywhere on your system, so it works with the non-picture files too.īoth programs look past the obvious filenames and dates that may be different even for files with the same content. I am in no way affiliated with dupeguru or any of the developers, just a satisfied user, and YMMV depending on your specific needs. If your photos have EXIF tags, you can also try the “EXIF” scan method which is much faster." If all you need to find is exact duplicates, just use the standard mode of dupeGuru with the Contents scan method. Every picture has to be individually and fuzzily matched to all others, and this takes a lot of CPU power. This very cool capability has a cost: time. It can detect duplicate photos even if they are not exactly the same. This scanning method is very different from methods.
"Why is Picture mode’s contents scan so slow? The software does use EXIF tags where they exist, excerpts from the dupeGuru FAQ: The best part is that it's freeware, so you don't have to lose anything to give it a try. I have gone through large volumes of music and photos (though definitely not the 15TB you are talking about) and it did a very admirable job. Even though it's freeware, it's pretty customizable and has a very small footprint. Nearly 20 years as a pro, and unfortunately in my earlier years I was not great at file management. I am in need of cleaning and reducing the amount of data and much is due to a high number of duplicate files. I have an enormous amount of photos on my computer, and mostly on two Drobo arrays totaling more than 15TB. All I seem to find is cheap software, that doesn't look like it's up to the task at hand.
Does anyone have any tips for me? I am seeking a duplicate photo finder that is the best for photo professionals.
