It's not big news that celebrities and models get photoshopped all the time, however it was really hard to tell just how much Photoshopping had been done.
Researchers in the Department of Science at Dartmouth College have finally developed a software tool that can rate photos based on how much digital altering has been done.
"We have developed a quantitative and perceptually meaningful metric of photo retouching. Photographs are rated on the degree to which they have been digitally altered by explicitly modeling and estimating geometric and photometric changes. This metric correlates well with perceptual judgments of photo retouching and can be used to objectively judge by how much a retouched photo has strayed from reality.
Below are some sample photos from their research published in the journal of National Academy of Sciences this week.
