In my opining, light painting is a kind of photographic technique that people use the camera to record the movement of the light in a dark environment with a slow shutter speed. So that means it has the camera setting required. Like the dark environment–because the light’s movement only show upon the dark environment. The low shutter speed– because you will make some post or need time to let the light dance in the darks. The tripod– because you need a thing to support your camera stable, or your picture will be blurry. The different kinds of light–because different light can make different typesof light. Also the most important thing is the creative idea–because you do not want your picture looks boring.
