Photos Blur Not Remove

Photos will blur instead of removing, if it recognizes a face. TDon't use the tool on faces, unless you want to blur them, so the person cannot be recognized, when you share a photo.

Let me introduce you to my great aunt and uncle

Being dead and all, they won't mind my using their faces.

Unfortunately, Uncle Orville has a spot on his forehead. It's a very old picture.

I used Clean Up to fix him up.

So Clean Up works fine for removing blemishes. You just don't do it to the whole face, unless you want blurring.
