Without making it sound like a pun, there is a difference between the types of photographs. It is what intent the focus is placed. The similarity is in the processing of the image. That is the same whether you are doing Still Life, Architectural, Glamor, Nudes, Street, and so on....photography. It is in the result where the distinctions arise.

Street photography does have a cousin in stagecraft. More precisely, "Staging" or "Blocking". We try to work the environs to move the eye to the "subject". It is done by vignetting a story. Every bit of photography rules are applied, and even broken, to have the 'subject' of the story to be limned.

In my high school English class, I had a teacher who would assign us books to read. The school provided the paperbacks. He would place them on our desks just prior the class arrival. When we got seated, we were required to read the first two paragraphs in the book. The rest of the period, we had to write what the rest of the book was about. After a while, it was awesome as to how close we would get. The point is that if are observant, we pick up a lot more clues than we might think.

My personal difficulty is that there too many stories going on when I am shooting on the street.
