Dogman I think that sometimes many get caught up in capturing the noun or as Weston called it the obvious. Sometimes that makes for very crisp clear renditions of say a bird. But does that image go beyond the noun or as Weston said, the obvious? Does it capture what the creator feels about what he is photographing n a deep sense?
I to am a huge fan of Evans as well as many of the other FSA photographers of that time. I think it should always be about if the image and the technique matching the vision. I think it was Haas that said and I am paraphrasing; I would rather make bad photographs that look like mine than beautiful photographs that look like everyone else's.
I also do not believe that single photographs tell stories. Bodies of work and documentary projects and series of images very well can. Winogrand said it far better than I could ever say it in this clip about 1:27 in.
