Fashion Bags - Light Painting
"Light painting adds an element of uncertainty, a touch of the
experimental. It demands creativity, is short on predictability. It's an
adventure, and it's fun.
Light painting results when a hand-held light source—usually a
flashlight of some type—is used in a dark room or outdoors at night to
illuminate a subject. When you make a light painting, your camera's on a
tripod with its shutter open for a timed exposure while you walk
around and illuminate parts of the scene or subject with the light." (Source)
