So I'm coming to this thread late, but in sifting through a lot of this interesting discussion, I am seeing a predominantly literal interpretation of both the Eggleston and Crewdson photographs. For instance, the Crewdson image of the snowy street scene is not documentary, or news, or landscape, and so critiques of "it's just a street" or "I could have done that" are irrelevant. (Especially because "I-could-have-done-that's by definition in fact didn't do it - quicker to dismiss the one who did and shut down.)
A quick Crewdson google search took 2 mins to reveal to me that he is creating these images by a highly controlled process, which leads me to the conclusion that everything in the image is precisly the way he wants it - thus offering me the chance to spend some time enjoying looking. Sort of the point of Art I think.
A good critique doesn't include "I'd have done this or that" statements... critique what's on the wall - what's there? Rather than just seeing a street, some snow, a car - yes, all very boring in and of themselves - how are these objects presented? What do they mean as a whole? The details? The narrative? Who's the person under the marquee and where is he going? I have a litany of questions that the image invokes. Art is supposed to be enjoyable! To enjoy savoring color, quality of light, detail, balance, spatial relationships - that's the show folks. If you're not into it, maybe you're not into art photography. One of the greatest obstables art photography has to overcome when presented to a general audience, is the burden of the assumption that the photograph is a picture "of something."
