Tomorrow I'm making a full day trip to the Subway slot canyon. I can't wait!
Photo 1: The photographers start lining up to get the best spot (I had it). See the black tripod with no camera on it and no person - that's where I was.
Photo 2: EOS 1Ds mIII; 24-70mm lens (at 42mm); Singh-Ray Gold n Blue polarizer and 4x6" 3 stop ND grad handheld in front of the lens. ISO 100; 2.5s @ f/20
