Distant scenes are subject to haze due to atmospheric effects on light and can be
easily overexposed. For this reason, first use the Lumisphere and measure by
standard method from the camera position. Then point the Lumisphere toward the
sun and measure. Determine exposure from the mean of the two obtained values.
easily overexposed. For this reason, first use the Lumisphere and measure by
standard method from the camera position. Then point the Lumisphere toward the
sun and measure. Determine exposure from the mean of the two obtained values.
Note: To obtain the mean of the two values, perform as follows.
Transfer mean value of the two footcandle indications (aperture
scale) to the dial.
Example: If 320(8) footcandles and 80(4) footcandles are obtained,
the mean value becomes 160(5.61. In the case of 80(4)
and 40(2.8) footcandles, the intermediate becomes the
desired value. Consequently, transfer that value to the
dial.
Transfer each footcandle value to the dial to obtain exposure. In cases of the
same aperture, setting the shutter speed to the average is acceptable.
Memo pointer is useful for memorizing the first measured value.
