OldBooth full review
The idea of taking a modern photo, cutting out the face and blending it into an antique photo is the premise of Old Booth.
However, it isn’t in any way an original idea because AbsoluteVintage, another app on the Mac Store, does exactly the same thing in exactly the same way.
OldBooth has vintage photos for the 20s, 80s and a couple of Christmas ones. There’s quite a few, though some placeholders for the photos were actually empty. Having selected a photo, or mask, you can then load in your modern-day photo. These are quite likely to be hi-res so will need scaling which actually performs a crop. You can also use the iMac camera.
