NOW, here's how to paint with light!
You need a camera on a tripod, a cable release, a very dark room, and flashlight(s) with or without colored cellophane or a filter over the flashlight lens. You can use a colored filter over the camera lens too, if you like, but let's keep this simple, ok?
Arrange your subjects and frame them in the viewfinder with the room lights on. Then turn off the lights, begin the exposure, and play the flashlight over the subject, moving it constantly to prevent hot spots. It's trial and error, so try one exposure at 15-20 seconds, another at 30-45 seconds, and another at one minute, perhaps. I usually set my f-stop at f-16 or so.
