– 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.
