Green laser pen and purple-gelled LED flashlight on the side of a wrecked semi-trailer. I shot this as a demo during one of the last Pearsonville night photography workshops.
The laser has interchangeable lenses; this one breaks the beam into hundreds of smaller points of light. I taped it in the on position and set it on the ground, off camera, left, about 20 feet away. It was totally stationary. I left it on for about 30 seconds of this 2 minute exposure. The purple was skimmed down the side of the trailer from the right, just enough to add a little variance to the color.
