Most high street ‘labs’ scan film at 72dpi for CD, which is only good enough for websites. The Fuji Frontier and Noritsu film printers can scan at much higher resolutions, but they won’t get set higher as it takes much, much longer for a film to go through and be scanned. I only get my films scanned that way when I need to e-mail photo samples quickly, when I need high res scans, I use my Nikon Coolscan IV. Sometimes, if I can afford it, I’ll get my films processed and scanned at a pro lab, usually Genie in Wandsworth, where they’re scanned at 300dpi, which is high enough for large format printing. I recently got myself a Canon Canoscan 9000f for my medium format films and 35mm IR, so far, I’ve only tried a few test scans, of 120 format, it’s been OK, but does tend to scan a bit soft. It did get slightly higher reviews than it’s Epson equivalent.
