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.
