“Theres actually a study some guy did where he says grandpas left arm angle is impossible because the top of this left shoulder should be raised upward.”
Oh, well if some guy did a study, I guess that means case closed.
My take on the “floating hand” is that the camera just happened to catch grampa as he was putting his hand on Barry’s shoulder, but wasn’t quite there yet. The hand was in motion when the shutter opened, and the “fatness” is just a bit of blur (of course, if you look at his other hand, he DOES have fat fingers to begin with).
If someone was really serious about creating a fake picture with Barry in the middle, why would he include that weird looking hand, knowing that it would immediately be cited as proof of fakery? That just doesn’t make sense.
This whole thing is just a joke that someone played on the world and a lot of people have taken the bait.
