I’m alternately infuriated and amused by the wonders of photo manipulation on the various CSIs. It would be really cool if there were some psychic version of Photoshop that could work over compressed pictures until they contained more information than the originals. I could draw stick figure comic layouts and have them worked up to full comic art.
Interpol, however, have achieved a bit of Photoshoppery they think is worthy of Grissom and the gang. Taking 200 photos of a paedophile abusing young boys they “untwirled” the effect that was used to obscure his face. Inerpol refuse to say how they did this, but several commenters on BoingBoing have pointed out that it’s just a matter of doing the same manipulation with negative values.
