With a bit of elbow grease and a DSLR, a few large-format-film-buff hackers have built a rig to scan in photos at a much higher resolution than your average desktop scanner.
The DIY DSLR lightbox has been around for a few years, but only for traditional 35mm film, the dominant format for film and still photography. This new model is specifically for large-format film, from the popular 4″x5″ format (which is 16 times the size of a 35mm frame–and thus has 16 times the resolution) up to 8″x10″, after which it reaches “ultra large” format resolution.
