==== Flash ====
A [[Flash (photography)|flash]] provides a short burst of bright light during exposure and is a commonly used artificial light source in photography. Most modern flash systems use a battery-powered high-voltage discharge through a gas-filled tube to generate bright light for a very short time (1/1,000 of a second or less).{{Efn|The older type of disposable flashbulb uses an aluminum or zirconium wire in a glass tube filled with oxygen. During the exposure, the wire is burned away, producing a bright flash.<ref name="Britannica-Camera" /> |name=|}}<ref name="Britannica-Camera" />

Many flash units measure the light reflected from the flash to help determine the appropriate duration of the flash. When the flash is attached directly to the camera—typically in a slot at the top of the camera (the flash shoe or hot shoe) or through a cable—activating the shutter on the camera triggers the flash, and the camera's internal light meter can help determine the duration of the flash.<ref name="Britannica-Camera" /><ref name="Warren-35mm" />

Additional flash equipment can include a [[Diffuser (optics)|light diffuser]], mount and stand, reflector, [[soft box]], trigger and cord.
