A new photograph-analysing tool quantifies changes made by digital airbrushers in the fashion and lifestyle industry.
“Publishers have legitimate reasons to alter photographs to create fantasy and sell products, but they’ve gone a little too far,” said image forensics specialist Hany Farid of Dartmouth University. “You can’t ignore the body of literature showing negative consequences to being inundated with these images.”
In the Proceedings of the National Academy of Sciences study, Farid and doctoral student Eric Kee debut a computational model developed by analysing 468 sets of original and retouched photographs. From these, Farid and Kee distilled a formal mathematical description of alterations made to models' shapes and features.
