Seriously, I've previously seen photographs of celebrities with and without make-up, and you could definitely see the difference there, but what they just did with that girl is, well, rather impressive. I especially liked the Photoshop bit - I didn't think they actually modified images, beyond lightning and maybe removing a few skin deficiencies that makeu-up couldn't take care of.
