Digital imagery has a big handicap: the lack of the 'original'.
Artists & collectors do need the original to sell, store or exhibit. You can't do this with digital files. That's why film won't die completely, people who need originals, will keep it alive.
I must take issue with this. A RAW is every bit as much a legitimate "original" as a negative. To suggest that because it represents a record of a something measured by a sensor and stored in a file makes it somehow less legitimate or lacking in quality is completely bogus. The "interpretation" done by the sensor and circuits is no different, in effect, from the "interpretation" by a film's color sensitivity and other characteristic curves. Yeah, with film light falls on the film and makes an original. So what? With digital, the very same kind of light focused by the very same kind of lens falls on a sensor and is stored in a different but equivalent manner.
Can you exhibit an original RAW file? Sure, and it'll be as pointless as exhibiting an original negative. If you mean prints, then you have a greater range of options with a digital file than you do with a negative in terms of producing prints for exhibition.
Can you sell a digital file? Of course you can. When I license an image for something, the client gets a file. This is true whether the original shot is film or digital. Same with anything for publication in a magazine. If I'm making fine art prints to sell, it generally starts with a file.
I reject completely the concept that a digital file cannot be an original. The file that came out of the camera
is the original. How can it be anything else?
All the same, a RAW file has a number of advantages over a physical negative. One big one is storage. I can't burn archive copies of a negative to a DVD and house it at a remote facility while still having an identical copy to work with at my fingertips any time I need. That there can be more than one original is a clear ADVANTAGE if you care about the longevity of your work.
I don't see why film, digital, and their various users have to be at odds or somehow serve to divide photography into categories of varying legitimacy. Digital isn't going anywhere and, at least for the foreseeable, neither is film. Past certain basic economic factors, they are not in direct competition as I see it. They are different tools, both with distinct advantages or disadvantages. Claiming the outright superiority of one over the other is myopic at best. People claiming digital isn't photography are just as wrong as those screaming that film is dead.
And for the record, I'm about to order 200 rolls of 120 and am working on getting set up again for making Palladium prints, primarily from digital negatives.
