What's real anymore?

Here's a neat quiz: Fake or Foto. The challenge is to determine which of the images is real and which was created in a modeling program. I got nine out of ten, and while I'd like to say it's because I'm a brilliant genius with an eye for detail, I have to admit that I just went with my gut on a few of them. There's a couple that are obviously fakes--but the rest are hard.
