Moon Walk, photo by Harold Davis. View this image larger.
This is a shot by moonlight, taken in the high, arid White Mountains along the California-Nevada border.
The two minute exposure gives the clouds some motion, and makes for a dreamy effect.
Properly exposed, moonlight can seem as bright as daylight. The light of the moon is slightly cooler in color temperature than sunlight, but the only way you’d know for sure this image was captured at night is by looking for the stars.
