Why do we Manipulate Photos?

They say a picture is worth a thousand words. This saying means that for every picture that has been taken, there is a story behind it, and you can usually read that story. But if we manipulate a photo, is the story still there? Do we really add to the story by doing that? Look at the many cases where photo manipulation has been used: OJ Simpson being made to look darker, Marthat Stewart's head was placed on someone elses body and the picture for Wisconsin Univertisy, where a black kid's face was edited in to show they were multicultural. Most of these cases are extremely untruthful. The OJ Simpson mugshot was darkened in Time's version, to make him seem more evil and more guilty. At the time, when this and Newsweek's mugshot came out, OJ was on trial for the murder of his wife. People who read Newsweek thought he was not guilty, but Time's readers injstantly knew he was guilty, because of his darkened mugshot. We should wonder if Time was using it's power of influence because they thought OJ was guilty, so everyone who read Time should have thought that. 'How much is too much'? I think that any photo manipulation at all is too much. When someone takes a photo of anyone or anything, the photo should be taken to show true beauty or wonderous shots. When one manipulates, they are taking away what the person has to offer, and replacing it with lies and things the person doesn't actually have. This also causes a problem because when we see a glamorous picture of a movie star that has been manipulated, and then we see their real image, they look like they have let themselves go. When we see these pictures, we treat them like they should be this glamorous all the time, but they're just people, shouldn't we all just like people for who they are?
