I am going through many old photographs on my Mac, deleting duplicates that have occurred for one reason or another. However, I realise that I may have deleted the wrong duplicate in some cases. I have deleted several hundred duplicate photos, across multiple folders. I have my whole hard drive backed up in Time Machine. However I don't want to simply restore all the files in Time Machine for my photos folder since I have made some changes since doing the deletion that I want to keep. There are too many files involved to hunt for them in Time Machine individually. Is there a way I can identify the files in a folder in Time Machine that **do not** exist in the current filesystem? And then a way to restore them. I think the command line tool `tmutil` may be helpful but I am not experienced with this.
