photoshopped or not

I read an article called "photoshopped or not" by Steve Lohr, this article was about "Dr. Farid and Eric Kee proposing a software tool for measuring how much fashion and beauty photos have been altered." by looking at the picture above you see that people photoshop things and picture, sometimes even too much. Overall they just do it to make people look prettier like they're face and they're bodies. but that is not always a good thing because some people look up to stars and models and singers they see on television or on a picture and think they are so pretty, but sometimes they could look just like you. so people should not compare their self to any model or singer or even actor because how they look on television might not be how they look in person.
