Interesting topic. It reminds me of the editorial that ran in _LensWork_ a couple of issues ago that discussed the gap between how most people look at photographs and how photographers seem to expect their photographs to *be* looked at---so who is our audience anyway?
My gut feeling is that this isn't necessarily different in kind from the gradual drift to smaller formats; plenty of people have complained over the years that eyes accustomed to 35mm fail to appreciate fine large-format work, and so on. Those people are probably somewhat right, and the equivalent complaint about digital changing the perception of film probably has a reasonable basis too...
The situation is analogous to what happened in popular music during the digital transition. Virtually, any middle-class kid can own (and many do) a digital instrument and/or software that lets them create music with surprising ease. However, have we really seen a proliferation of superb music lately? I do not think so.
Oh, I do. I hear lots of really superb music produced by amateurs (and by semi-pros who are getting paid but not making a living---little local bands and so on), and I think that's a direct result of the wider availability of musical technology---digital recording facilities as well as digital instruments per se. Much of that music is "amateurish" in that it isn't highly polished, highly produced, or a technical showcase; personally, I like that aspect---remembering as always that the root of "amateur" means "love". I'd much rather hear the work of a technically marginal musician whose love for the art comes through than that of a consummate professional who's phoning in their performance. And many of the amateurs *aren't* technically marginal, they just haven't chosen to make their art a full-time job for whatever reason.
Moreover, I think that analysis pushes right through to photography: I see lots of images that have something special about them, taken by "amateurs" in both senses of the word, on both film and digital. The availability of digital technologies (scanning as well as digital cameras per se) means that there are a lot more of these people showing off their work; I think that's great, because it drastically expands the universe of images that are out there to look at.
That doesn't speak to what's special about a gelatin silver print, much as the musical version doesn't speak to what's special about the sound of a Stradivarius in hands that are as good as the instrument. But those things are still out there to enjoy; they just live in a more complicated artistic landscape. At the end of the day, I think that "artistic biodiversity" is a Good Thing.
