Duplicate Photo Find & Remove

I have tried 2 cleaner programs AVG which I own, and I have tried Avast which I do not own. I also have tried Duplicates, and the other Duplicate Cleaner program all which are not very good but try them yourself because I do a lot of Snapshots. I have found that this program is much more reliable for my use for both photos, snapshots, and videos at almost a hundred percent. The only reason I didn't give it a 5 is because everyone can improve. I will own it shortly

Good for when a duplicate file finder app isn't enough. This one doesnt just scan for copies by file name, it actually scans the photos as well and even very similar ones. The only downside I found in the few minutes I used it, was when the scan is over and your results pop up. So you click the photos to see which one is better that you should keep, and when you back out of photo back to your scan results, all your prior photos checked to delete are gone. Can be worked around.

As with, apparently, all these sorts of apps, it simply refuses to find all duplicates, or VERY similar pics, I've got a folder with over 300 pics in it, I know there are at least 3 images with a similar copy, not 100% identical, but slightly different edits of the same image, those 3 might be all there is, altho across the board there could be more I haven't spotted, this app can not for the life of it find those 3 particular similar images, the only real difference must be a slight crop difference and brightness, why can't it mark them up? No app like this can, I tried copying the whole folder, and true enough it can mark up each and every image as dupes, but with those 3 similar images in 3 different groups, just the 100% identical match, I've set the similarity setting to 10%, it should find these damn pics, if it's missing those 3, who knows how bad these apps actually perform, clearly they can't actually scan an image to see if they're similar at all, that's a lie, all they can do is look for images with the same res and file size.
