This is a photo of Crepuscular Rays taken just before a massive electrical storm that led photographers to evacuate from the Pinnacles Viewpoint in Badlands National Park. The shot was taken with a Nikon D 7100, Nikkor Zoom Lens (18-200 mm.), and a .9 Soft Lee Graduated Neutral Density Filter. The ISO was 200, F/18, 1/40th second exposure, and a Focal Length of 95 mm. I used a Gitzo Tripod and Arca-Swiss Head.
