I photographed this panoramic of Horseshoe Bend in Page, AZ in 2007. It was photographed after sunset with my Canon 5D and 24-70mm lens and is a multi-photo stitched panoramic. Split neutral density filters were used to balance the extreme brightness levels between the sky and water.
In order to photograph this, I had to have my tripod legs within inches of the edge of the cliff wall, some 1400 feet above the Colorado River.
