The Grand Canyon lends itself well to black and white with its amazing lines and textures. This was taken as a storm cleared out. In color the photo wasn't anything special, but monochrome highlights the shadows and color gradations of the canyon. It also emphasizes the horizontal striations of the cliffs and the same horizontal lines in the clouds. Converted to monochrome in Nik Silver Efex. Gear: Canon 5D MkIII, 24-104 mm lens, tripod.
