4. Basic Operation

3. When set for incident light

Incident light measuring is the measurement

method that employs either the Lumisphere or

Lumidisc functions.

Measure with the lumisphere ai med in the

camera direction at the position of the subject.

1) Using Lumisphere to Measure

Lumisphere is used to measure people and buildings and other such solid

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.

2) Using Lumidisc to Measure

This is used to measure manuscripts, paintings or other flat copy, or

otherwise for measuring light contrast (see page 18) or using as an illumino

meter. To switch to the Lumidisc function, slide the Lumisphere mounting to

the right (same as if measuring reflected light), insert at an angle section B of

the Lumidisc into slot A of the light receiver and then press down the strap

eyelet C to secure the Lumidisc.

The Lumidisc is removed in reverse order to the mounting method.

At this time the strap eyelet of the Lumidisc should be pulled away from the

main unit.

NOTE: ● Be sure to handle the Lumidisc correctly to prevent damage that

may occur if mounting or removal is incorrect.

● Do not fit the Lumidisc next to the Lumisphere when you take

incident light metering Otherwise, the Limidisc will affect the

exposure in reading.

● The Lumisphere is an important light receiving unit. Please

handle with care and try not to mark or soil.

Wipe Lumisphere with a dry soft cloth if it becomes dirty.

Never use organic cleaners (like thinner or benzene) to clean
