A wonderful rainbow emerged just after it had stopped raining at the tufas at Mono Lake. This image was taken with a Nikon D 7100, Nikkor Zoom Lens (18-200 mm.), and a Cokin 3 step Neutral Density Filter. The ISO was 100, F/18, 1/5th second exposure, and a Focal Length of 55 mm. I used a Gitzo Tripod and Arca-Swiss Head.
