Turn that frown upside down

Okay, I just had to say that, sorry. It's for this story in which it suggests flipping your camera upside down in order to get better pics. Why does this work? According to the article, the flash hits you in a different angle upside down than when you shoot rightside up, and as a result, the pics will show fewer wrinkles and blemishes.

Well, at least that's what the article SAYS. I plan to try this myself - probably ON myself - just to see if it works. When I have, at the very least, somewhat convincing proof, I'll post it here. And don't worry, I'll flip the upside down pics around so that they're rightside up.
