I've been asked to photograph two-dimensional artwork in a gallery for their records. Needs to be negative film so they can archive the prints. I've done Google, PNet, and APUG, and I've got a lot of the details down fairly well. But most the film information is for slides. I am confused about looking for tungsten negative film, and the appropriate kelvin bulbs...I don't see it advertised on B+H, for example. If tungsten film isn't available, which daylight film would be recommended, then which floodlamps would match that daylight film?
