4. Basic Operation
4. When set for reflected light
•
This method measures the brightness (luminance) of the light reflected from the subject. It is
useful for distant objects such as landscapes, when you cannot go to the position of the subject,
or for metering subjects that generate light (neon signs, etc.), highly reflective surfaces or
translucent subjects (stained glass, etc.).
< Using the lumigrid > (Receiving Angle 54°)
1.
Remove the Lumisphere
The lumisphere unit is removed by holding both the
upper and lower sections of Lumisphere retracting
ring q and turning it counterclockwise while pushing
the Lock lever !4 downward.
2. Mount the lumigrid
To mount Lumigrid @3, align the mount/removal
indicator on the Lumigrid with the mark and, while
pressing it, turn it in the clockwise direction and
secure it in place by raising the Lock lever until it
clicks into place.
3. Take measurements by aiming the lumigrid precisely at the area of the subject to be measured
from the position or direction of the camera.
4. Follow the same procedure to mount the lumisphere.
CAUTION:
• Be sure to avoid touching the light receiving section when mounting or removing the lumisphere
or lumigrid.
< Using the viewfinder > 1°, 5° and 10° Non-Parallax Spot-Finder (NP finder)
The Non-Parallax Spot-Finder mounted on the meter,measures the light of the exact area you
are viewing.Since the Spot-finder is measuring the reflected light (light reflecting off a
subject),measurements should be taken at the camera position.
