The world took notice when an eye-opening time-lapse video showing how an image can be so drastically changed using only Photoshop went viral last week.
Now the woman in question has been identified.
Sally Gifford Piper, the 36-year-old model in the video, and her husband Tim Piper, who directed it, spoke to ET about why they created it in 2011.
“I feel really angry about the pressure on women and the reality is that most of us don’t look like these perfect women,” Sally said of her "Body Evolution."
"I think that there needs to be a celebration of all different shapes and sizes. And we need to see more variety and I’m determined to fight for that.”
