Identifying Manipulated Images

Posted by CmdrTaco on from the check-that-out dept.

Jamie found a cool story at MIT Tech Review. (As an aside, it sits behind an interstitial ad AND on 2 pages: normally I reject websites that do that, but it's a slow news day, so I'm letting it through.) Essentially, software is used to analyze light patterns in still photographs. Once you can figure out where the light sources are, it becomes a lot easier to determine if an image has been photoshopped.

    It just sounds wrong to say that an image has been "GIMPed".

    Actually, now that I think about it, I kinda like it...

    im just tired that "photoshop this" "photoshop that" like there would not be any other image manipulation software

    Do you also hang around the Epson at work explaining to people how they aren't really "xeroxing" anything?

    Playboy is probably the worst offender at this. Most of the women these days are so heavily airbrushed/Photoshopped that they look more like paintings or cartoons than actual photos.

    Er... I mean... I just read the articles, but that's what a friend told me about the pictures.

    You could probably find out if you googled it.
