Nikon World has an article with Dave Black discussing light painting techniques. If you’re not familiar with it, light painting is just what it sounds like: during a long exposure, use a light source (flashlight, laser pointer, flash gun, etc.) to paint a scene. The article goes into more depth about different techniques that can be used for small objects like a flower to large scenes like an ice climber.
It’s a fun technique and good for any bored photographer with a camera, a dark room and a flashlight.
