Light at the end of the Tunnel

Yesterday I spent the day hiking along an abandoned railroad corridor along the Salmonberry River in the Tillamook State Forest. We happened upon a tunnel – inside it was pitch black and you found yourself literally staring at the light at the end. I set my camera on a tripod and tool a series of seven exposures which I later merged. My ever photogenic dog, Cookie, managed to stay still through all seven of them! This image is the result.
