Balance

When calculating a desired lighting balance, the meter can be used to measure the

brightness of main and fill-in lightings from the subject position.

t. Mount a Lumidisc instead of Lumisphere for usual incident light measurement.

2. Select the measuring mode, and set the film speed (ISO) and shutter speed (T) as

shown in the paragraph for "Preparing the Meter for Operation".

3. Point the center of Lumidisc accurately toward the center and axis of the main lighting

source from the subject position, and measure the light according to the measuring

method for the respective mode.

4. Using the same procedure, measure the fill-in light. In this case, be sure that the meter

is held so that it is not influenced by the main lighting source.

5. The F-stop difference between the main and fill-in lighting sources is the lighting

contrast ratio (Fig. 18).
