SETTING FLASH EXPOSURE COMPENSATION
Turn the setting dial 9 so that the desired compensation value is
opposite the Index LED 9a .
If you want to have uncompensated fl ash exposures you have to
reset the compensation value to
0
Tip:
– Dark subjects against a bright background:
positive compensation value
– Bright subjects against a dark background
negative compensation value
Notes:
• The description above applies only to cameras that do not allow
such settings themselves. With other cameras, the fl ash
exposure compensation must be set on the camera. Read the
camera's instructions for this.
In the latter case, fl ash exposure compensation settings on the
fl ash unit are ine ff ective.
• It is not possible to alter the fl ash exposure by changing the lens
aperture since the camera's automatic exposure control treats
the changed aperture as a normal working aperture again.
• When setting a compensation value, the fl ash range changes
according to the following pattern:
Positive compensation value = lower range
Negative compensation value = higher range
Also see the guide number table in the Appendix.
VIDEO LIGHT -
Ever more cameras are fi tted with a video recording function. As an
alternative to the fl ash function, this fl ash unit therefore o ff ers an
integrated video light 2 .
• The status LED 9d lights up as an indication that the light
brightness can be controlled.
Setting the light brightness
Turn the setting dial 9 so that the desired output level is opposite
the Status LED 9a .
With Lithium batteries, the lighting time at maximum brightness
(i.e. with setting at
1
) is approx. 3.5 hours.
