Manipulated Photography By Leszek Bujnowski

Another famous instance of controversy over photo manipulation, this time concerning race, arose in the summer of 1994. After O.J. Simpson was arrested for allegedly murdering his wife and her friend, multiple publications carried his mugshot. Notably, TIME Magazine published an edition featuring an altered mugshot credited to Matt Mahurin, removing the photograph's color saturation (perhaps inadvertently making Simpson's skin darker), burning the corners, and reducing the size of the prisoner ID number. This appeared on newsstands right next to an unaltered picture by Newsweek.
A further noted example is the Adnan Hajj photographs controversy (2006), when the photographer in question retouched war images using the clone tool to increase the size of a smoke plume and to duplicate flares.
There is a growing body of writings devoted to the ethical use of digital editing in photojournalism. In the United States, for example, the National Press Photographers Association (NPPA) have set out a Code of Ethics promoting the accuracy of published images, advising that photographers "do not manipulate images that can mislead viewers or misrepresent subjects." Infringements of the Code are taken very seriously, especially regarding digital alteration of published photographs, as evidenced by a case in which Pulitzer prize-nominated photographer Allan Detrich resigned his post following the revelation that a number of his photographs had been manipulated.
