This is normally one of my favorite photos of the cottonwoods in bright yellow with side lighting. Something happened to them as well as the oaks which have completely lost their leaves early. This photo was made on November 3, 2011 with a Canon 5D MkII camera using the Canon 24-105mmL zoom set to 47mm. The exposure was 1/125 sec. at f/13 using ISO 400.
