06.1 FLASH TRIGGER
There are several possibilities to trigger your DÖRR DFX studio flash:
06.1.1 Flash triggering through remote flash trigger
(OPTIONAL ACCESSORIES)
We recommend triggering your flash with a remote flash trigger which works wirel-
ess and reliable. You will need an optional remote trigger kit, consisting of a remote
transmitter and a remote receiver. The remote transmitter is connected with the hot
shoe of your camera while the remote receiver is connected with the SYNC socket
(21) of your studio flash.
06.1.2 Flash triggering via SYNC cord
Professional cameras offer a SYNC jack. Connect a SYNC cord (optional) to the
SYNC socket of your flash (21) and the PC jack socket of your camera. Releasing
your camera triggers the connected studio flash at the same time.
06.1.3 Flash triggering through IR flash
An IR flash (optional) emits light in infrared spectrum. IR light is invisible for human
eyes; nevertheless it will be recognized by the incorporated photo cell/slave cell
(14) and triggers the flash. Press photo cell On/Off button (16) to turn this function
on or off. When activated, the photo cell LED (16a) will light up in red. Caution: The
photo cell and IR flash need to be in direct line of sight in order to trigger correctly.
Any object within the line of sight might cause the flash not to trigger.
06.1.4 Flash triggering with another flash
The DÖRR DFX studio flash may be triggered e.g. with an on-camera flash. Mind
to turn off the pre-flash function of your on-camera flash as the photo cell/slave
cell (14) will be triggered by this signal. Make sure to turn the power of the camera
flash to a minimum, e.g. 1/128. This setting allows using the light of the on-camera
flash only to trigger the DÖRR DFX studio flash, without having another disturbing
light source.
06.2 TAKING PICTURES WITH DÖRR DFX STUDIO FLASH
After selecting the trigger mode (radio, IR flash, flash, sync cord) turn on your ca-
mera and the DÖRR DFX studio flash (main switch (23) position I = On).
06.3 CAMERA SETTINGS
06.3.1 ISO
Choose lowest ISO setting in your camera menu, e.g. ISO 100 to achieve optimum
picture results.
06.3.2 Exposure time
Choose the exposure time not shorter than the flash synchronization time of your
camera. For most cameras this value is about 1/250s (for details please see the
technical data of your camera). As standard value for studio photography 1/125s
was established. In studio photography the exposure time has no influence on the
picture result.
06.3.3 Aperture
Set the aperture to the desired value, e.g. f11.
