Separating "art" from "craft" defines this more clearly for me.
Modernism separated art and craft. There are many great modern painters who are not anywhere near as good at the craft of painting as the old masters, yet they present extraordinary artistic expression - as strongly or more so as the old masters.
Digital vs. film is a question on the "craft" side, it has little to do with artist expression or result.
A great and popular trompe l'oeil painting displays great craft, but little artistic power. Some great (the greatest?) artists master both the art and craft.
I disagree that digital is the same as film (a "negative"). Film has the property of being an original and an object present at the scene, touched by the artist, that collected light reflected directly from the subject. This varies in importance and significance, but owning HCB's or Ansel Adams' negatives, for example, is different from having digital copies of his pictures (well beyond commercial rights). To me it's similar to having an original painting vs. a print.
The net result of digitization and easy post processing, and the controversy versus film stems from the fact that it obviously 'cheapens' the medium - which is a question of "craft".
That doesn't change the "art" of the image.
