I was introduced to light painting by Peter Anger,
http://www.peteranger.com/ and have found it a most fun way to make photographs. These photos are long exposures in low light, sometimes on a tripod, sometimes hand held. When hand held, usually moving the camera.
I like both the pure light where the model operating the lights cannot be seen as well as capturing the model in action with lights swirling around.
