2.3.3 Fill-in flashes

Using fill-in flash makes it is necessary to coordinate flash and ambient light. For this purpose

you should bring your DIGIFLASH 2 into incident light measuring method and proceed as

following described.

 First you take a reading of the background in the function „ambient light“. Transfer the EV

value from the display to the setting window 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 2 towards the

camera in such a way that the meter will only receive 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 ambient light. If not, adjust the power of the flash unit or

change the distance to get the desired EV value.
