This image of a snake like dune was taken at the first appearance of the sun. Contrast this image with, another image of this Dune that was taken just 3 minutes earlier and see how fast the dunes change with the light. Once the Sun is up a photographer, on most days, has only a few minutes to capture dramatic light.
Black and White relies on contrast and this image seems to be alive with contrast at the first touch of light. Taken in the Mesquite Dunes of Death Valley California close to Stovepipe wells.
