Light painting, or light drawing, is a photographic technique in which exposures are made by moving a hand-held light source while taking a long exposure photograph, either to illuminate a subject or to shine a point of light directly at the camera, or by moving the camera itself during exposure.
My daughters and I had fun experimenting with light painting recently. They used a small flash light to create these designs. We happen to catch my pup in the first one. 🙂
