This photo was made by several layers, to make the dunes I used blue fabric and then color corrected it to make it look like sand, then I replaced the background with the sky and placed the lamp later in photoshop.
Equipment Setup:Camera: Canon 40D
Lens: Sigma 17-35 DG HSM
Flash: Lumopro LP160 @ full power and a Clairex Flash as a kicker for the lamp
