I have just finished scanning over 17K pics for my wife's family with my Canon DR-C125 duplex auto sheet fed scanner. I now have thousands more B-W negatives from the early 1900s to scan. They are all size 616 film. Seems to me if I could (software or hardware) turn off the front lamp I could sheet feed the negatives and batch convert in my image program. The resolution (600dpi) would be OK for this project. As anyone done anything like this?
