This is a photo of sunrise at the Oxbow: Grand Teton National Park. It was taken with a Nikon D 7100, Nikkkor Zoom Lens (18-200 mm.), and a Lee .9 Soft Graduated Neutral Density Filter. The ISO was 320, F/18, a 1/3rd second exposure, and a Focal Length of 48 mm. I used a Gitzo Tripod and Arca-Swiss Head.
