Wireless TTL Flash
(only for cameras featuring W-TTL)
For many objects a lateral flash is more advantageous then frontal flashing. Illumination will
be more balanced and thus more convenient. The DÖRR DAF-44 Wi is fitted with the advanced
wireless TTL function. You can enjoy creative photography with multiple lightings from various
directions. Before starting, you should be familiar with the following details:
Master Flash: A master flash is required to control and release one or more distant flashes.
Depending on the camera model, the incorporated camera flash (Nikon) can
take this function and/or a computer flash can be mounted to the camera that
is ready to fulfill the master function (Nikon, Canon).
Remote Flash: The DÖRR DAF-44 Wi can be used as a remote flash (distant and not connected
to the camera). You can use one or more remote flashes. There is no limitation
on the number of remote flashes set in one time.
Groups: In wireless photography you can assign remote flash units into any of the three
groups: A, B, or C. You can set the mode and output levels for each remote
flash group. Example:
• Flashes in group A work in normal TTL mode
• Flashes in group B work with TTL mode with 2/3 f-stop minus correction
• Flashes in group C work with manual flash and ¼ power ratio
Depending on the camera model, different numbers of remote flash groups can
be controlled. Please read your camera's user manual.
Channels: It may happen on photo shootings that many photographers work with similar
flash technology. In order to avoid interferences, the DÖRR DAF-44 Wi offers
3 channels (1, 2 and 3) for wireless operation. You can use the channel of your
choice for communication between master and remote flash. However, you
need to make sure that both master and remote flash are set to the same
channel
Wireless TTL Flash with DÖRR DAF-44 Wi
How to Proceed
1. Make sure that the slave mode switch is at OFF position.
2. Press the MODE button until the STTL icon is shows up on the LCD then press the ⬆and⬇
buttons until the desired channel and group are displayed, e.g. STTL 1A. When the wireless
TTL mode (STTL) is activated, you will see red AF light blinking at the flash front.
3. Adjust the desired flash angle using the flash´s ZOOM button.
4. Now get the DÖRR DAF-44 Wi to the desired position and be aware that:
- it should not flash directly into the camera
- the sensor for wireless TTL flash is not covered
- there is no obstacle between master and slave flash.
The sensor at the remote flash must always be directed towards the master flash. It is
advisable to position the remote flash in a way that the sensor points exactly to the the
master flash. Then you can turn the flash reflector to the desired direction.
- the maximum wireless TTL flash control range is app. 10m for frontal position and around
7m for lateral position of the remote flash (can vary depending on the ambient light
conditions)
- the remote flashes of one group should be position aside of each other
- the sensitivity of the sensor for wireless TTL flash control at the remote flash can be
strongly reduced by direct sunlight. It may be necessary to protect the flash from direct
sunlight using a shade or umbrella.
5. Once all flashes are positioned properly, check the settings again. Now you can start taking
pictures.
