Conversely, the person trying to master all of the photography needs to break it down into composition, lighting, even the best use of the technology itself. He is also going to need to know about how to deal with models, and there is a lot of math that goes into mastering it. The would-be master will need to know all of that and do so with minimal thought. He needs to break down the general skill of “photography” into several discrete steps so that he can master each step before going on to the next.
