Light painting is probably the fastest growing technique seen these days, and for good reason; the creative possibilities are endless, and can make for some stunningly beautiful art when done correctly. At its core, light painting is another long-exposure technique that utilises in-frame or out-of-frame light sources to create patterns within the photo or illuminate an object in specific locations.
It is possible for the artist to actually perform the painting in front of the camera without appearing in the final shot, due to the ratio of time the photographer is painting to the actual exposure duration.
How it’s Done:
Any number of light sources can be used, although generally flashlights are the most common. Light pens, candles, and various fiber optics can be used as well. The sky is the limit, use your imagination! Like with other long-exposure photography methods, a tripod must be used. Set your camera for a long exposure (30 seconds or more), and use a remote shutter release if available (or the timer function available on almost all cameras will work as well).
The actual location you shoot in should be as dark as possible, obviously working at night is best. We want the object you’re drawing or highlighting to stand out as much as possible against the dark background. Since we’re shooting a long exposure, we can set our aperture to a smaller setting; start with f/8 to f/16 and experiment from there. This will ensure crisper shots with a full field of depth.
