I went to Svarttjønna, south-east of Trondheim, to tent with the kids for one night. When they were asleep I went around in the area taking pictures of the sunset. This is one of the last pictures I took. It was so dark I had to have the shutter open for over 12.5 minutes. The little stream is illuminated by walking back and forth with a little led light for about 2 minutes.
