Compared to the previous Flatirons picture, this one is much more dynamic, based primarily on the lighting and the use of a very wide angle lens that emphasizes the sweeping nature of the sky. The blues and yellows (opposites on the color wheel) add even more tension to the scene. I compose images like this, not with all of these compositional elements in the forefront of my mind, but rather on a much more intuitive level. When presented with such a vista, I'll usually reach for a very wide angle lens, and look through it to verify my intuition before final composition and recording.
