Dartmouth prof. analyzes first ever "Photo-shopped" image

Farid, a dig­i­tal foren­sics ex­pert, told theMail:"Al­though we may have the im­pres­sion that pho­to­graphic tam­per­ing is some­thing rel­a­tively new - a prod­uct of the dig­i­tal age — the re­al­ity is that his­tory is rid­dled with pho­to­graphic fakes."

Farid said the air-brush­ing of im­ages by bru­tal dic­ta­tors — like Josef Stalin, Adolf Hitler and Fidel Cas­tro — to re­move en­e­mies from pic­tures was com­mon.

He added: "Al­though there are many his­tor­i­cal ex­am­ples of pho­to­graphic fakes, time-con­sum­ing and cum­ber­some dark­room tech­niques were re­quired to cre­ate them."
