Some photo forensics

13 Aug 2013 | tags: science

Over at Chemistry-Blog there is an article about some alleged manipulation of images in a couple of papers. Having been sent some dodgy images in the past (a story I can’t really put online but suffice to say they didn’t make it to publication) I thought I’d share a very useful website - FotoForensics. FotoForensics uses a technique called Error Level Analysis that doesn’t confirm image manipulation but accentuates/highlights areas in an image that may have been saved a different number of times to the rest of the image.

I thought I’d run the images posted in the Chemistry-Blog story through this analysis and see what came out, I’ll leave the interpretation to the reader.
