Pure WheelThere something about a white sky that I like about photos. Perhaps is the way I was taught how to use negative space in architecture to affect moods. That puts in in good stead to start applying it in photography. It is always in the back of a photographers mind when they are composing. The more you do it the less you have to think about what you are doing. It just sort of becomes natural to you. I am not sure where I am on that scale but I like to think that it is nearly natural. But if you stop thinking about composition, then what will happen?
