I have hundreds, perhaps thousands of 2 1/4 inch negatives (Hasselblad) taken by my grandfather that I need to convert to digital images. What is the easiest, most economical way to do this? Is there a machine such as the SmartScan for 35 mm slides that I could use for this size slide? I really can't afford to have them done professionally and would prefer to do it myself. Any ideas appreciated.
