This is a photo of waning light at White Sands National Monument, featuring pink glow of the distant mountains. I used a Nikon D 7100 with a Nikkor Zoom Lens (18-200 mm.), and a Tiffen Circular Polarizer, attached to a Gitzo Tripod and Arca-Swiss Head. The ISO was 200, F/22, 1/15th second exposur, and a Focal Length of 200 mm.
