I just borrowed OH's free PC format disc lol
It has a couple of programs on it one called digital photo enhancer, apparently specific to removing noise and enhancing pics
Second a nifty little program for removing wires, atennas etc from shots called wire pilot, looks to just be working on the cloning tool leaves somes dots if your not careful though
Heres one i tried with the Photo enhancer not quite sure on it, i really need a pic with lots of noise , i think it needs a fair bit of time tweaking
