Photo Manipulation

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.
Social and cultural implications
The growing popularity of image manipulation has raised concern as to whether it allows for unrealistic images to be portrayed to the public. In her article "On Photography" (1977), Susan Sontag discusses the objectivity, or lack thereof, in photography, concluding that "photographs, which fiddle with the scale of the world, themselves get reduced, blown up, cropped, retouched, doctored and tricked out". A practice widely used in the magazine industry, the use of Photoshop on an already subjective photograph, creates a constructed reality for the individual and it can become difficult to differentiate fact from fiction. With the potential to alter body image, debate continues as to whether manipulated images, particularly those in magazines, contribute to self-esteem issues in both men and women.
