When set for incident light
1.
Incident light measurements can be performed with the lumisphere fully extended or in the
retracted position. You can switch between Lumisphere in the up position or retracted position
by firmly rotating the Lumisphere retracting ring q until it clicks.
2.
When the Lumisphere is raised
This is used to photograph 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 light axis of the lens) at the position
of the subject.
3.
When the Lumisphere is lowered (flat diffuser function)
This is used to photograph manuscripts, paintings or other flat copy. It can also be used for
measuring illumination levels (see page 25), or brightness difference (see page 23).
NOTE:
• If the device 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 manually.
• 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.
