You can really use any B&W film to do separation negatives. Kodak did make special films to do it and masking for things like dye transfer but really as long as panchromatic B&W film is available from some manufacturer it can still be done so I think it will still be an available process for many years to come. Now, dye transfer is a different issue and I cannot say if anyone offers materials for it. My intent is to use one of the newer Epson inkjets like the 9880 or 11880 for color and another similar machine but modified to do Paul Roark's "Carbon on Cotton" process for B&W. Now I only have a 9600 which has a more restricted magenta side gamut. But shooting in-camera separation negatives could potentially go to many different print processes. What I like about this process in larger film formats is that it is a standardized way to expose images that has near infinite flexibility for post production output. I can make an exposure today that will be as good as print technology of the future can use. In digital what comes close is a choice of Phase One, Better Light, Hasselblad H4 camera or 39 Mpix V series back or Leica S2. All are way expensive and if you shoot landscapes theft or robbery is always a concern. They all take batteries and in winter here batteries are problematic. With in-camera tricolor on film on 4x5 and up you can still best all of these digital solutions. The Better Light has the same subject motion issue because it scans. Really the Hasselblad H4 with 60 Mpixel sensor is probably the best of the lot but at a cost of $50K and up it is way expensive. Sep negs are finicky but hey the Russian was doing pretty well way back in 1905 to 1915. Ed |
