I liked the opposite facing shapes of the two sand dunes in this image. The edges of the dunes almost makes an "S" curve. The sky was a solid blue and in black and white makes the image more absttract without any clouds. The low sun angle of the early morning sky shows the ripples in the sand in the foreground. I used the Pentax 6x7 rollfilm camera on this trip, as it has the largest rollfilm negative available and is easier to handle on the dunes.
