This is a fascinating composition because there are patterns in both the sand and the sky and they form the essence of this print.  This print was photographed in June of 2006 in the Great Sand Dunes of Colorado National Park.  It was a clear day with occasional broken clouds and a persistent wind which has been present almost every time I have visited the dunes.  The patterns caught my eye as I walked along a dune ridge and I had to descend to the base of that ridge to get in a position that maximized the play of these patterns in the sand.  This is the print which resulted from my time spent there.  To accomplish this I used the Mamiya RZ67 with the 50mm ULD lens stopped down to f/32 (tripod mounted and mirror-up) to expose this image on Kodak Portra 400 VC.
