Light painting, also known as light drawing or light graffiti is a photographic technique in which exposures are made usually at night or in a darkened room by moving a hand-held light source or by moving the camera. In many cases the light source itself does not have to appear in the image. The term light painting also encompasses images lit from outside the frame with hand-held light sources.
