Yes I understand that manipulation of images has been going on since basically the beginning of photography. However, upon close examination it is pretty apparrent that these images were faked. But today with digital, how do you know if it has been faked or not?
If I take a picture of someone holding a gun outside of a bank that got robbed with a digtial camera and delete the file leaving only the printed photo, would this be admissable as evidence? Could the defense attorney argue that there is nothing to prove the image was not manipulated, that the man had something else in his hand and I added the gun later?
On the other hand, if I make an image of a politician walking out of the back door of a motel with a 12 year old girl in here underwear on film, would not the film be proof enough that it really happened? Would the existence of film, that could be examined by experts, protect me from a lawsuit if nothing else?
So, does it not make sense to use a camera that provides physical proof of the truth that could be scientifically examined? With a dgital camera, unless you have the actual flash card the image was first on, how do you ever prove the image was "real"?
