First light across the dunes was a dramatic sight. The dune directly in front of me caught the brilliant first light of day, while the dune behind was still in shadow. This moment lasted only a few seconds. If you look hard at the background dune, you can see traces of sunlight on the tops of the ripples. A moment later everything was in bright sunlight. I was lucky to be set up and just waiting for the sun to break.
I experimented with this image to create a B&W version. I felt that the bright area was just too much in the B&W version. I like the warm tan sand contrasted against the grey background shadow in color version. Below is the B&W version. Choose for yourself.
