Ron. I think this is where EXIF information might help. It is info that is embedded by a digital camera at the time of shooting and includes details right down to the serial numbers of the equipment and also a � symbol I believe. I'm sure Martin Evening can enlighten us more because I think Pixel Genius, a company he is involved in work in this area. Logically I suppose you might have to produce the camera instead of the neg!
