I agree that style is not subject matter. I always thought that style was an interaction between who I am and the context that sourounds me. This interaction comes through the best, in my opinion, when I'm pushing myself well beyond my confort zone. In terms of randomness vs. deliberateness, photographs deliberately made in a series are more likely to show a "style" or who I am, particularly when the photographs are hard to make physically and/or emotionally. I use to walk out of the house, camera in hand, and just make pictures of anything I found interesting. In my case at least, not many of these were ever printed. Since about 4 years ago I only shoot in "projects", and as it turns out these are always very difficult projects. Either way, random or deliberate, it's all very pleasurable
