It was a good read and interesting site in general, but the question is how much of the realisation happens in camera and how much happens during editing. I think an awful lot happens intuitively in camera and then during editing the actual name for the spacial relationships might be apparent. Certainly a great deal of knowledge and awareness helps, but I also suspect a lot of images work because that's where the elements were at the time and the photographer got lucky in fulfilling certain compositional forms. When images neither fall into place nor are worked into place, they do not pass editing and are forgotten about. When a photographer produces a shot with masterful composition, the tendency is to assume that the photographer intended it that way and was fully conscious of those qualities at the time of capture. In many cases, the contact sheets also make an interesting contribution to the discussion.
