Hi all. I"m going to buy a scanner, but I'm not sure what to look for. Almost all of them do a pretty good job of scanning old family snaps, but what else should I be aware of? Also, how does film scanning work? I've seen some with slots for negatives, etc. Can I insert developed film and a scanner will pull an image off it? Can most scanners handle 120 film? Does it have to be cut? Some pointers and personal experience would be greatly appreciated, the sales guy yesterday was thick as wood.
