The front end of the North Lake Tree Tunnel is in perfect color. I hope it lasts through the weekend as I’m teaching another workshop there. I’ll post the leaf situation on Thursday after the snowstorm. This photo was made on October 4, 2011 with a Canon 5D MkII camera using the Canon 24-105mmL IS zoom set to 45mm. The exposure was 1/125 sec. at f/11 using ISO 400 and a Polarizing filter. For more information on exposure and lighting, check our Tips and Techniques section.
