Charles would like to use a Nikon film scanner to scan his collection of slides. Leo says that Nikon Coolscan 5000 is one of the best scanners out there, with a max DPI of 400 PPI. But they're expensive, and he'd still have to clean each slide or have spent a lot of time and money for nothing. Another option is a dual lit scanner by Epson, that comes with a bulk loader. On top of that, scanning takes a lot of time. Leo recommends a service like ScanCafe because for the same price, they'll not only scan your slides, but they'll clean them and color correct as well. Would they also scan negatives? Leo says they likely will, with an optional adapter.
