I think you should be able to both think and photograph analytically. You should have an idea of what you want to photograph and why you photograph it the way you do, and you should be able to articulate that idea. That said, if it requires ten sentences full of opaque, polysyllabic latinate words to articulate your vision, you need to sit down and read "Politics and the English Language" by George Orwell, and quite possibly get smacked upside the head with a 50 lb. Unix manual. Own your vision in your own terms, don't allow it to be couched in inauthentic language that only satisfies an academic audience who has decided that aesthetics have no place in art.
