Metz MECABLITZ 36 AF-3 - Manual (Page 86)

7.2 Flash synchronisation
7.2.1 Normal synchronisation
In normal synchronisation the mecablitz is triggered at the
beginning of the exposure time (1st curtain synchronisa-
tion). Normal synchronisation is the standard mode on all
cameras, and is suitable for most flash shots. Depending
upon the given mode, the camera is changed over to flash
sync speed, the customary one being between 1/30th sec.
and 1/125th sec. (see the camera’s operating instructions).
No settings have to be made on the mecablitz, nor is there
any display for this mode.
7.2.2 REAR - Second-curtain synchronisation
Some cameras offer the facility of second-curtain synchroni-
sation (REAR mode) triggering the mecablitz by the end of
the exposure time. Second-curtain synchronisation is parti-
cularly advantageous when using slow shutter speeds (slo-
wer than 1/30 sec.) or when shooting moving objects that
have their own source of light. Second-curtain synchronisa-
tion gives a more realistic impression of movement because
the light streaks behind the light source instead of building
up in front of it, as is the case when the flash is synchroni-
sed with the 1st shutter curtain! Depending on its operating
mode, the camera uses shutter speeds slower than its sync
speed.
The REAR function is only possible with cameras fea-
turing this facility. The corresponding setting is made
on the camera (see operating instructions of the given
camera).
7.2.3 Slow synchronisation / SLOW
In certain operating modes, some cameras permit slow flash
synchronisation (SLOW) which will provide added promi-
nence to the background at lower ambient light levels. This
is achieved by matching the shutter speed to the ambient
light. Accordingly, shutter speeds slower than the flash sync
speed are automatically adjusted by the camera. Some
