This was taken at sunset last winter on a quiet day with no people on the big dune. Try finding that in the summer! I shot an exposure (several really) for the dune, and one for the sky. In Photoshop I combined the best two shots to get a more evenly lit, less contrasty image. I also warmed up the blue shadowed dune to match the warmth of the sunset. As always I shot several views. I used my tripod because of the slow exposure for the deeply shadowed dunes and to match it with the sky shot.

Hope you enjoy it,
