A light meter is a device used to measure the amount of light. In photography, a light meter is often used to determine the proper exposure for a photograph. Typically, a light meter will include electronic digital or analog circuitry, allowing the photographer to determine which shutter speed and f-number should be selected for optimum exposure, given a certain lighting situation and film speed.
Light meters are also used in the fields of filmmaking and stage design, in order to determine the optimal level of light for a scene. They are used in the general field of lighting, where they can help reduce the amount of light residues used in the home, outdoor light pollution, and plant growth to ensure adequate levels of light.
