There is a bright light at the end of the tunnel. This picture was taken while I was approaching the exit of the westbound tunnel of the Hampton Roads Bridge Tunnel. Notice the ceiling is white over the left lane and black over the right lane where the large trucks are confined. My Canon G10 was mounted on "The Pod", a beanbag camera mount, and placed on the passenger side dash. The exposure was 1/6s at f/4.0, ISO 400, 30mm equivalent focal length and the camera was fired with a Zap Shot wireless remote.
