Here's an interesting bit of flash that reveals the transformation of a model using makeup techniques instead of photoshop. It's a pretty dramatic change, if a bit odd. It's on the New York Times site which I think requires a free registration. Worth a quick look here: http://themoment.blogs.nytimes.com/2...cobs-beauty-2/
I confess that part of the appeal is the little device used to slide one photo up to reveal another beneath. A pretty cool way to see the differences between to version of an image.
