Though most digital cameras include built-in or automatic light meter adjustments, many film cameras require manual F-stop adjustment, and an accurate light meter reading is necessary for proper exposure. The two basic varieties of light metersreflected and incidenthave two different procedures for use.

Instructions

Reflected Meter

    1

    Position the subject. Since reflected light meters don't interact directly with your subject, you'll get the best results if roughly the same amount of light falls on both the camera and the subject. For instance, do not place the camera in bright sunlight and the subject in the shade.

    2

    Set the meter's ISO value. Match the ISO value of the film you use.

    3

    Hold the meter near the camera, with the sensor pointing toward the subjectdepress the test button.

    4

    Read the results and match the camera's F-stop and shutter speed according the meter.

Incident Meter

    5

    Position the subject. Since an incident light meter measures light directly on the subject, the camera placement will not alter the reading.

    6

    Change the meter's ISO setting to match the ISO of your film.

    7

    Hold the meter near the subject, with the sensor facing the intended camera position and press the test button once. Note that if the subject is partially shaded, the sensor will take a reading appropriate for the portion of the subject testedso take a reading on the area of the subject you wish to properly expose.
