A light meter is a device which measures light, and determines the correct aperature setting for proper exposure. To use it, first set the meter to the film speed you are using (ASA), then select a shutter speed. Next, hold the meter as close to the subject as possible, with the sensor pointed toward the camera, and activate it. The meter will then indicate the correct f-stop for the shutter speed selected based upon the available light. Light meters are most useful during difficult lighting situations...such as snowscapes, studio work, and high contrast situations. Under these conditions it is often difficult to get an accurate reading with your in-camera meter.
