I was running after dark with a full moon up. So I carried with me my p&s camera + a tiny tripod. I got an idea of combinating the tree silhouettes from 'contre luz' of the moon with the artificial blinking light from my 3 diodes running light.
Exposure of aprxm 10 sec allowed me to jump and dance in order to make the red light be prolonged dots . However at the end of the exposure, I stumbled across a thin wire from the electrical fence, that I hadn't spottet in the dark. But I got the motive, which I had in mind!
