I was wondering if could be possible to create brand new sprites basing this work on REAL photos. I mean, you take a good and almost perfect set of pictures of your hands (maybe holding a pistol, a melee weapon, or anything you want) and then you re-elaborate them with some graphical program (ex:Adobe Photoshop, etc.): for example using filters and darkening layers to make hands more similar to those in Doom. That's what I want to do in order to create a brand new weapon. What do you think about this way of making it? Anybody of you already tried this without/with success?
Any suggestion or tip is very well accepted.

PS: I already made a set of my hands holding a typical italian pistol, but I haven't treated graphically those pics...
