Great point but what I meant, and should have made clearer, is the "aesthetic" aspect of each photograph. This context is independent of the emotional narrative. Each photograph has a technical explanation contributing to the aesthetic that is easily taught and applied. The OP covers the narrative, as your selected quotes nicely demonstrate.
Ah ok, I think I get you. Is it right to say that the technical factors used to take and process a photograph influence the emotional "look and feel" (aesthetics) of the end result, separate from the bigger-picture story and context behind what is being photographed, and by whom? The former can be taught, whereas the latter is mostly a product of circumstances. Though I guess you can improve your chances of encountering powerful stories by traveling, carrying a camera wherever you go, working as a photojournalist, etc.
