Today there was a thin dusting of snow in the North Lake (stop 16 on the map) area. These leaves contrast nicely with the white snow. This photo was made on the road to North Lake on October 7, 2010 with a Canon 24-105mm zoom lens set at 55mm on a Canon 5D MkII full frame sensor camera. The exposure was 1/180 sec. at f-8 using ISO 400 and a polarizing filter. For information on exposure, lighting, filters and composition, please check our Tips and Techniques section.
