Flashes
A flash produces an instantaneous flash of artificial light typically around 1/1000 to 1/2000 of a second. They are mostly used to help illuminate scenes that do not have enough available light to expose the photograph. Flashes are used for other reasons such as capturing quickly moving objects or creating a different temperature light.

Light Meters
A light meter is used to determine the proper exposure for a photograph. It allows the photographer to determine which shutter speed and aperture to set their camera to in a certain light situation and with a certain film speed.
First, set the light meter to the correct film speed you are using. You place the light meter a a point where the light is brightest on the subject. The light meter will tell you what the aperture and shutter speed you should use for a more accurate exposure of the film.
