– Trigger the flash.
– Transfer the value measured from the
display to the window in the printed sca-
les above and set it precisely under the
red indicator line.
– Read the f/stop in the upper part of the
scale opposite the sync speed you had
preselected (for 1/90 read between 1/60
and 1/125).
2.3.3 Fill-in Flashes
You will find the right combination in two
steps:
First you take a reading of the background
in the function „ambient light“. Transfer the
EV value from the display to the setting win-
dow above. Then set the corresponding
combined shutter speed and f/stop to your
camera, while taking care that the shutter
speed must be equal to the flash sync
speed.
In the second step, you determine the fill-in
flash by measuring the flash in the incident
mode. From the shadow area of the subject
you direct the Digiflash towards the came-
ra in such a way that the meter will only re-
ceive the fill-in flash and the stray light, but
definitely not the main light source.
The resulting EV value should be lower by
1 to 2 stops than the EV value for the ambi-
ent light. If not, adjust the power of the flash
unit or change the distance to get the desi-
red EV value.
