Adobe Tackles Photo Forgeries

Several readers wrote in with a Wired story about the work Adobe is doing to detect photo forgery. They are working with Canon and Reuters (which suffered massive bad publicity last year over a doctored war photo) and a professor from Dartmouth. (Here is Reuters's policy on photo editing.) Adobe plans to produce a suite of photo-authentication tools based on the work of Hany Farid (PDF) for release in 2008.

    Will it involve digital micro dots?

    Yes, Adnan Hajj's unfortunate images were "doctored" as in "given too much medicine," the medicine being dust & scratch removal.

    But it was not faked, nor was image content "cloned" with that tool.

    This Image Is Not Faked

    The next step, if someone was paying me for this, would be to try to replicate the disaster using some readily-available dust & scratch removal software, like Sane for the GIMP.

    If Hajj's lawyer or Reuters were laying appropriate bucks at my feet, I would explore the problem through SciPy and PIL.

    Hajj's disastrous image is an example of the kinds of errors we will have to get used to recognizing.

    In the olden days, we would correct scratches by putting a drop of light mineral oil on the negative and putting glass over that. The oil filled in the scratches similar to the way the DCTs fill in the scratches nowadays.

    Reuters deserved some reputation damage, as Hajj's photos aren't all that great and quite obviously Reuters's photo editor was asleep at the switch.

    But accusing them of publishing faked photos is in this case fakery itself: pretending to knowledge that nobody has.
