Interesting that you put it that way. I don't think Stephen Shore's work is about art—i.e., that he's thinking about art or that he's trying to create an artwork. His work is about seeing, about being aware of the world that surrounds us, about paying attention (he devotes a fascinating chapter in his book Modern Instances: the Craft of Photography). It's a question of "communicating a perception of the world" as he says, quoting Walker Evans, and seeing what meaning, if any, comes out of it.
In many ways he's a traditionalist because a lot of his concern, from a technical point of view, is the same one as all painters who have done landscape for the last 2,000 years, that is, how do you organize three-dimensional space on a flat surface. Difference of course is that he's interested in what is there, about the landscape and about topography, and what meaning they convey (often from a cultural point of view).
It's not at all an intellectual stance, as people too lazy to read him tend to assume. It's about connexion—about connecting with the world, or, as he puts it in the article (and elsewhere): "While I may have questions or intentions that guide what I’m interested in photographing at a particular moment, and even guide exactly where I place my camera, the core decision still comes from recognizing a feeling of deep connection, a psychological or emotional or physical resonance with the picture’s content."
In that sense, he's close to Robert Adams. He wants you to look, to pay attention, to wonder what meaning (if any) lies within. So you can't really approach him with your "artistic sensibility," or, at least, very differently than you would a tableau by Monet, Van Gogh or Degas. It's a different kind of sensibility this kind of photography calls for. Going for "artistic" is like bringing a match to light an electric stove.
It's not that it's void of artistic intent: just the way he works with color—the sheer beauty of color and the way they play within the frame—is proof of that. It's just that there are other factors at work in our appreciation.
