My wife and I spent the day hiking, photographing and playing amongst the sand dunes. There are no trails, so we hiked out to the tallest dunes. As the sun started down, I started looking for an image that showed the sand dunes as they disappeared over the horizon. The light-colored sand and the harsh shadows created the layered look and diagonal lines that I was looking for. Even the layered clouds created horizontal lines.
