Remember that guy in the newspapers that appeared on disgusting child porn with his face distorted which an expert team from Interpol tried to uncover (which they really did a good job at see above)? I tried it myself with Photoshop CS3 and it turns out to be a simple "trick". An other proof that whenever you make alterations with photoshop do not be so sure that other people cannot recover the retouch. Guess I have to be more carefull in the future... :-)
