I'm not sure if all scanners that can scan film work like mine, but I have a hp scanjet 5400c, and it has a special attachment that lets you scan negatives and slides. You slide the negatives or slides into the attachment, and place it on top of the scanner bed. Then, when you're saving the negatives, you can either save them at negative size, or 300% magnification, which ends up being just about the size of a normal print. I think they're saved as TIFF files, but I'm not sure. Its a very handy contraption, very easy to use. Hope this helps!
