I have a shoebox full of negatives that belonged to my mother. I'm in my 60's, and there are a lot of large (2 3/4" x 4 1/2") negatives from the 40's that I want to review and scan into my computer to print. I can't tell by the advertising writeups whether there are any such scanners that can work with negatives that large. I would like to have the names of any that can do that, but I'm not able to pay a really high price. I would prefer it to be below $300 at the very most. Can anyone help me?
