Techniques
By moving the light source, the light can be used to selectively illuminate parts of the subject or to "paint" a picture by shining it directly into the camera lens. Light painting requires a slow shutter speed, usually a second or more. Light painting can take on the characteristics of a quick pencil sketch.
Light painting by moving the camera, also called camera painting, is the antithesis of traditional photography. At night, or in a dark room, the camera can be taken off the tripod and used like a paintbrush. An example is using the night sky as the canvas, the camera as the brush and cityscapes (amongst other light sources) as the palette. Putting energy into moving the camera by stroking lights, making patterns and laying down backgrounds can create abstract artistic images.
Light painting can be done interactively using a webcam. The painted image can already be seen while drawing by using a monitor or projector.
The
Equipment that you need
A variety of light sources can be used, ranging from simple flashlights to dedicated devices like the Hosemaster, which uses a fiber optic light pen.Other sources of light including candles, matches, fireworks, lighter flints, glowsticks, and Poi are also popular.A tripod is usually necessary due to the long exposure times involved. Alternatively, the camera may be placed on or braced against a table or other solid support. A shutter release cable or self timer is generally employed in order to minimize camera shake. Color Gels can also be used to color the light sources.
Location shot - find a location with some ambient light.Find an object that is less "hit" by that light.
