Bought to photograph some negatives with my iPhone (now finished, hardly used). Holds 120 negative strips flat and is suitable to scan the different sized 120 frames (6x6, 6x9 etc). Note if using it to you photograph negatives as a standalone system it will need a light source behind it to backlight the negatives (I rested it on an iPad). However, this is actually a tray insert for Canon scanners. Compatible with Canon CanoScan 8000F 8400F 8800 8800F 9000 9000F
