Hey guys little photo editing question here. (hope got the rite place 4 it haha) Was watching CSI miami and they edited a photo … basically enhanced it when they zoomed in and reduced the pixels so they could see something in some ones eye’s … think it was eyes or glass’s 2 do with a crime im just wondering how you would reduce the pixels in a photo like that. I have Adobe CS4 so I dunno if u can do it on their or not?? I also remember leam Neason doing it in taken 2 c the reflection of the person taking the pic.

Overall? They're talking bull:P

I think you refer to noise reduction - i.e. replace pixels that show "noise" with pixels that a program believes should be there.

Maybe these programs exists, but truth be told, your best way is to open a picture in two instances Zoom one in so you see individiual pictures and begin working and guessing how it should work. Ant work if you ask me.

Ya I don't think cs4 has the ability to do something like that. If it was a vector image, you could do that because the graphic is based on a mathematical algorithm instead of physical (and set) parameters. It wouldn't surprise me though if technology did exist to .. fill in the blanks so to speak. I guess it would kind of be like mapping key points in an animation. I don't know how accurate something like that would be though..
