Seen out on my deck this evening... Experiments in painting with light. Thanks for the lovely comments, I've had a few asking how it's done. Easy! Get your camera on a tripod with a cable release. Set to bulb at some medium aperture. Hold the shutter open with the release, dash into frame and paint whatever you like with a torch pointed at the lens, then dash back out of frame and release the shutter. Hit and miss, but lots of fun!
