Passing this single tree on a bicycle tour inspired me to shoot a panorama for the Forests event. A forest consists of many trees, this could be one of them. You see more trees all around, where you can speak of a forest.
I shot the panorama with the help of a philopod and my Sony NEX 5 with the 16mm lens and the attached fisheye converter.
