When you take a photo you spend a little time setting up the scene as it will fit into the space you have in the view finder. That should continue into writing too. We are used to seeing movies and TV on a screen, not from our own eyes as we live our lives where the view is wider and taller. So when someone is reading a book they also expect to see the scene as if it were through a camera or on a screen. Set up your scene with that in mind. How many things can you bring into the screen and where do they fit in best?
Confused? Hold up your hands to form a box shape and see what actually fits into the space between your hands. Not as much as if you looked without looking through your hands, right? It is surprising how little sometimes fits into that square space.
