Host Bob Edwards talks to Dino Brugioni, a former senior officer of the CIA's National Photographic Interpretation Center about his new book,"Photo Fakery: The History and Techniques of Photographic Deception and Manipulation." Brugioni says people have been tampering with photos in order to fool or entertain others since the invention of photography. People and objects can be put in or taken out of pictures, or events can be staged for the camera. Brugioni says some manipulations in recent years...including the darkening of O.J. Simpson's mug shot on the cover of a national news magazine...can call into question the credibility of the news media.
