What Is Light Painting and How Is It Used in Photography?

A ‘light painting’ is an image that is created by capturing a long exposure of a dark scene that contains a moving light source. By moving the light source within the scene whilst the photographic medium is being exposed the photographer is able to produce an effect which resembles the brush strokes made by an artist’s paint brush, only composed entirely of light. A classic example of a light painting is writing your name using a sparkler at a firework display. Light Paintings can be created by capturing any moving subject with a light source against a dark background using a long exposure.
