9.4.2 Manual mode Qflash Compensation
This procedure will calibrate Qflash to an
incident light
flash meter you
use and trust. Note that only incident light measurements are reliable for
manual exposure settings.
1. Place the Qflash Trio
10 feet from the incident flash
meter that is
facing
Qflash.
2. The area surrounding the
meter and flash should be
similar to the shooting environment
you usually work in. For example,
in a large hall, there will be little light bouncing from walls and ceilings.
In a small room, the light meter reading will be increased by whatever
bounce occurs from nearby surfaces. These factors will affect calibration
and should be considered.
3. Turn the Trio on, set mode to manual (M) and change the manual
power setting to 1/8.
4. Set the film speed (iso) on the Qflash and the flash meter to the same
value.
5.Change the F number on the flash until the distance shown in the
display is 10 feet.
6. Fire the Trio. Note the F/number on the flash meter.
7. Press the
MAN
soft key,
then use the
UP
and
DOWN
soft keys, adjust the F/ number
in the display until it matches
the F/ number from the flash
meter.
