I was reading a thread here yesterday where someone was comparing herself to the women in Zoo & Nuts magazine at the time I thought "but even the women in the photos dont look like that,they have been ruthlessley photo edited into what men want to see"
The best example of before & after I could find on the net was here - the finished picture has had the skin tone, texture and hell even the belly button altered. Select the picture you want to look at, roll your mouse over and wait a second!!
