Light painting by moving the camera, also called camera painting is done at night or in a dark room. The hand held camera is used like a paintbrush for making patterns and create abstract artistic images.
By setting a camera at a longer exposure time, a variety of light sources ranging from single or multiple light sources like flashlights, festival lights, candles, matches, fireworks, lighter flints, glowsticks, etc. can be used for camera painting.
The inset picture is a camera painting created by me with the camera shake in front of a string of Diwali festival lights.
