How Photoshopped Is That Picture?

Freddybear writes "Digital forensics experts at Dartmouth have developed software that can analyze digital photos to rate how drastically they have been altered by digital editing techniques. 'The Dartmouth research, said Seth Matlins, a former talent agent and marketing executive, could be "hugely important" as a tool for objectively measuring the degree to which photos have been altered.'"

I use TIFF, you insensitive clod.

Nobody doing image alteration for anything beyond amusing the droolers at various low end web sites is going to use a lossy compression algorithm. In fact, you can set up any program written in the past 20 years not to compress the image, even using JPEG. So that sort of thing isn't terribly useful.
