Badbird: Trying to get all those fuzzy grey hairs right would be difficult I think.
For most people, it would be very difficult, but not impossible for an expert. I closely examined the photo, there is a "white" glow..slight but there, around his body and around his head, indicating
A body was photoshopped in, then the head was placed in as well. His hand is free of that glow
I have attached a photoshopped pic of Jonathan and I. It ha been photoshopped. If you zoom in you will see a very slight glow around the bottle, but not much around me....and I know for a fact I was photoshopped. So yes this can be done. Usually the photo is taken in front of green to make it easier to separate.
