Flash Synchronization - Dorr DAF-44wi Gebrauchsanweisung

TTL Flash Control with Aperture Priority
TTL also allows you to take shots with a focus range of your choice and aperture priority. Set
your camera to aperture priority mode (A) and the flash to TTL mode. 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 reduce. Your camera automatically con-
trols the flash synchronization period needed. Together with the TTL flash control it ensures
correctly exposed picture results.
TTL Flash Control with Shutter Priority Mode
Set your camera to shutter priority mode (S) and the 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 (x-synchronization) cannot be selected (most cameras automatically
prevent this). The camera´s automatic aperture function and the TTL flash control ensure
correctly exposed objects.
TTL Flash Control with Manual Exposure Setting
Set your camera to manual exposure (M) and the flash to TTL mode. Now you can set your
camera to an aperture and shutter speed at your camera of your choice. However, values
falling below the shortest flash synchronization period (x-synchronization) cannot be selected
(most cameras automatically prevent this). TTL flash control ensures a proper illumination of
the object despite of manual camera settings.
Manual Flash Mode Photography
Press down the MODE button 1x for manual flash mode. The LC display shows "M" followed by
the performance data. Via the⬆and⬇buttons you can reduce the full flash power 1/1 to 1/32 in
the following steps: 1/2, 1/4, 1/8, 1/16 and 1/32. Press down the MODE button until the desired
flash performance value is indicated on the LCD. The aperture on the camera needs to be set
manually. Depending on the aperture setting, the desired firing range can be varied. The LCD
now indicates the flash range given at a certain lens aperture setting.

Flash Synchronization

Synchronization time refers to the shutter speeds which will allow flash photography. Special
attention must be paid in the case of short shutter speeds. Each camera model features a
"shortest" synchronization - the so-called x-synchronization. Please review the user guide of
your camera. Shorter shutter speeds than the x-synchronization should under no circumstan-
ces be used in order to avoid incorrect exposures. Using the DÖRR DAF-44 Wi with TTL mode
the x-synchronization of your camera will be set automatically.
Exposure OK Indicator
The DÖRR DAF-44 Wi features an exposure control indicator. This indicator shows you whe-
ther the fired flash sufficiently illuminated the object or whether you should repeat the shot
using a shorter distance to the object. In case the illumination was sufficient, "OK" appears for
approx. 2 seconds on the LC display. Simultaneously the TTL OK light glows. The exposure OK
indicator is activated in TTL mode only.
Indirect Flash Photography
The DÖRR DAF-44 Wi is fitted with a bounce and swivel head which
allows you to change the direction of the flash up to 270° horizontally
and up to 90° vertically. You can avoid direct flashing onto objects by
positioning the flash towards a reflection surface. This surface should
be neutrally white (e.g. white ceiling, white wall) as the light will be
reflected in the color of the surface flashed on. This leads to color distortions when using
colored reflection surfaces. Indirect flash photography offers you the following advantages:
• avoids harsh shadows
• avoids red-eye effect
• soft outlines and even illumination (particularly suitable for portraits)
• avoids disturbing light reflections off non-metallic surfaces, e.g. glasses
