I have taken several trips with the renowned Native American Guide, Fred Cly, into the back country in Monument Valley in Arizona. In this photo Fred graciously agreed to pose on the lip of the Teardrop Arch (I have his written permission to post and publish this photo). I used a Nikon D 7100 with a Nikkor Zoom Lens (18-200 mm.), with a Hoya Circular Polarizer, all attached to a Gitzo Tripod and Arca-Swiss Head. The ISO was 100, F/18, 1/25th second exposure, and a Focal Length of 50 mm.
