Well, you can call it enhanced if you like, but all they did was clean her up & smoothe her out a bit. That's been done for a long time, especially in print media before the advent of computers. Models, landscapes, & whatnot. You used to have to actually etch the process films. That's why it's called "photoshop". I used to do it for a living. They didn't try to make her bigger or anything. Did thin her torso just a tad.
The truth is that you can't trust anything you see in any medium, especially with all the modern software & other gadgets. I could take a picture of you, put you on the sideline of a football game with a pair of Bruno Mahlis on your feet & the bloody knife in your hand, & nobody'd be able to tell the difference. I can do that without a computer. Nothing surprizes me on the internet.
