This a photo I took to the right of Lower Yosemite Falls, shooting through a rainbow. The trees and lower rocks in silhouette lend some definition to this otherwise ethereal landscape. I used a Nikon D 7100 with a Nikkor Zoom lens. The ISO was 100, F/18, and a 1/20th second exposure. I used a Tiffen Circular Polarizer and Gitzo Tripod with Arca-Swiss Head.
