I'm in the process of reading Ian Plant's book Visual Flow, which contains many tools and techniques related to image composition. I have a question for all of you "serious" photographers out there. How many of you take a deliberate amount of time to study the fine details of a potential photo before pressing your shutter button? Do you look at a scene and actually tell yourself "Maybe if I move a little to the left I'll be able to create a dynamic triangle in this image?" Or, "If I move to a higher elevation I'll be able to take advantage of some strong diagonal lines?" Do any of you get that specific in your photography, making it a conscious process, or do you just keep moving and looking through your viewfinder until you find a composition that strikes you as being pleasing or powerful or colorful or sedate or whatever without giving any serious thought as to why you feel the way that you do about the scene? In other words, how much of your photography is deliberate and how much of it is purely visceral?
