I'm sorry to crash your forum with a dumb question, but I have inherited a lot of negatives from our town's old newspaper, but I know nothing about photography. I'm trying to determine what format they are so I can find a scanner to digitize them. They are about 3.25 inches by 2.25 inches or 8.5 cm by a little under 6 cm. I think they started on a roll, but have been cut and stored in envelopes. Any idea what they are. PLUS if you have any ideas for a negative scanner, that'd be awesome. Thank you!
