TTL Flash Control with Automatic Time Release
TTL also allows you to take shots with a focus range of your choice and automatic time release. For this set
your camera to automatic time release mode and the flash to TTL. Now you can manually set your camera
to the aperture desired. Please keep in mind that by choosing a smaller aperture (larger aperture count) the
flash range will also reduce. Your camera automatically controls the flash synchronization period needed,
and together with TTL flash control correct exposed picture results are reached.
TTL Flash Control with Automatic Diaphragm Mechanism
First set your camera to automatic diaphragm mechanism mode, then set your flash to TTL mode. Now you
can set your camera to a shutter speed of your choice. However, values falling below the shortest flash
synchronization period can not be selected (most cameras automatically prevent this). Together with the
camera´s automatic diaphragm mechanism, TTL flash control ensures correct exposed objects.
TTL Flash Control with Manual Exposure Setting
Set your camera to manual exposure and the flash to TTL. Now you can set your camera to a shutter speed
of your choice. However, values falling below the shortest flash synchronization period can not be selected
(most cameras automatically prevent this). TTL flash control ensures a proper illumination of the object.
- For Nikon D40 & D40x owners: The flash can support an ISO speed up to 800 in full auto mode. It may not
perform as expected if the ISO speed exceeds the supported range.
Exposure OK Indicator
The DAF-42 features an exposure indicator. This indicator shows you wether the fired flash sufficiently
illumninated the object or wether you should repeat the shot using a shorter distance. In case the illumination
was sufficient, “OK” appears for approx. 2 seconds on the LC display. Simultaneously the AUTO OK light
glows. With activated beeper signal a beeper sounds once. The exposure OK indicator only activates in TTL
mode.
For Canon flash type: The ETTL indicator will light while connected with ETTL cameras.
For Nikon flash type: The LC Display will show TTL, I-TTL and BL in different way while connected to different
camera models. Please refer to the camera’s manual.
Manual Flash Mode Photography
Press down the MODE button 1x for manual flash mode. On the LC display appears “M” followed by the
performance data. Via the MODE button you can reduce the full flash power 1/1 to 1/16 in the following steps:
1/2, 1/4, 1/8 and 1/16. Press down the MODE button until the desired flash performance value appears on the
LC display. The aperture on the camera needs to be set manually. Depending on the aperture setting, the
desired firing range can be varied. The firing range at a certain lens stop can be read off from the flash range
indication on the LC display.
