==Description==
A '''flash''' is a device used in [http://en.wikipedia.org/wiki/Photography photography] producing a flash of artificial [[light]] (typically 1/1000 to 1/200 of a second) at a [http://en.wikipedia.org/wiki/Color_temperature color temperature] of about 5500 K to help [[illuminate]] a scene. A major [[purpose]] of a flash is to illuminate a [[dark]] scene. Other uses are capturing quickly moving objects or changing the [[quality]] of light. Flash refers either to the flash of light itself or to the electronic flash unit discharging the light. Most current flash units are electronic, having evolved from single-use flashbulbs and flammable powders. Modern [http://en.wikipedia.org/wiki/Camera cameras] often activate flash units automatically.

Flash units are commonly built directly into a camera. Some cameras allow separate flash units to be mounted via a standardized "accessory mount" bracket (a [http://en.wikipedia.org/wiki/Hot_shoe hot shoe]). In professional studio equipment, flashes may be large, standalone units, or studio strobes, powered by special battery packs or connected to [http://en.wikipedia.org/wiki/Mains_power mains power]. They are either [[synchronized]] with the camera using a flash synchronization cable or [[radio]] signal, or are light-triggered, meaning that only one flash unit needs to be synchronized with the camera, and in turn triggers the other units, called ''slaves''.[http://en.wikipedia.org/wiki/Flash_(photography)]
