4. Basic Operation

3.Incident Measurement Mode

Incident light measuring is the measurement method that employs either the Lumisphere or Lumidisc functions. Measurements should be with the Lumisphere aimed towards the camera direction from the subject position.

1.You can select extended or retracted lumisphere measuring positions by rotating the Lumisphere retracting ring (clockwise or counter-clockwise) until it clicks into position.

Extended Lumisphere

Retracted Lumisphere

 

(Lumidisc)

2.When the Lumisphere is extended. (3-D Light Measurement)

This is used to measure people, buildings, and other three dimensional objects. Measurements are basically made by the method of measuring with the lumisphere aimed in the camera direction (more precisely, in the direction of the lens axis) at the position of the subject.

3.When the Lumisphere is retracted (flat diffuser function)

This is used to measure manuscripts, paintings or other flat copy. It can also be used for Contrast function (see page 32) or measuring illumination (see page 34).

NOTE:

If the light meter is used with the Lumisphere retracting ring in a middle position, distributed light quality will change, and suitable measurements cannot be made.

Do not push the Lumisphere down with your finger or hand. Always use the Lumisphere retracting ring.

If the lumisphere becomes soiled, wipe it with a soft, dry cloth. Organic solutions (paint thinner, benzene, etc.) must not be used under any circumstances.
