Light painting is the art of creating photos by setting long exposure times on a camera and using a moving light source to “paint.”And light painting photographer opens a camera’s shutter and keeps it open as they draw in the air with a light source. The finished product is an image of that light source’s path: lines of light through darkness, creating a glowing image in the open lens during the long exposure photography time. Some of the most memorable types of light painting rely on light sources produced by the artist. Using a flashlight, illuminated tube, or flame, artists can paint nearly anything with light. It’s just a matter of precision, patience, and creativity.
