I spent over 10 minutes standing above the creek at Summit Park tonight just studying the shapes and contrast in the sand and creek bottom. My eye kept coming back to the two swirls that were separated by a dark rock. Once the sun was low enough in the sky, I quickly moved in for my shot. I suggest to shoot less, see more, and know exactly what is exciting you before you pull the trigger on your camera. F5 at 1/60, ISO 100, 18-50mm lens at 18mm
