Adjusting Flash Intensity
2. The Power Bar (Output Adjustment screen) for the selected
zone will become available.Hold down the Measuring button to
display the current ash intensity output at

and the Power
Bar in
4
above.
3. Either touch the plus/minus [+]/[–] symbols or move the bar with
your ngertip to set the values.
4. To select other zones and set values, repeat process 1 to 3
above.
5. The F value (f-stop) for each zone calculated out from the set
T(shutter speed) and ISO sensitivity value is displayed in
5
and
the average F value (f-stop) for all zones is displayed in
6
.
6. When ash modeling lamps are being used, touch
7
to
turn off the modeling lamp.
Touch
7
to turn on modeling lamps again if needed.
4) Pressing the Measuring button once will transmit information about
intensity change to the ash.
(At this time, the ash will be triggered, but the intensity will be the one
prior to intensity adjustment.)
To measure the intensity exposure of the flash after intensity
adjustment, the Measuring button must be pressed again.
5) Take a measurement by placing the meter at the position of the subject
with the Lumisphere facing toward the camera’s lens axis. The ash will be
triggered and the measured value (F value) at that time will be displayed.
6) Repeat process 4) and 5) of ash intensity adjusting until the desired F
values are obtained.
