Second Curtain Synchronisation (Rear); Slow Synchronisation (Slow) - Metz MECABLITZ 44 AF-1 digital Mode D'emploi

10.3 Second curtain synchronisa-
tion (REAR)
Some cameras offer the option of
second-curtain synchronisation (REAR),
in which the flash unit is not triggered
until the end of the exposure time.
This is particularly advantageous when
used with lower shutter speeds (slower
than 1/30 sec.) and moving subjects
that have their own source of light. With
second-curtain synchronisation, a
moving light source will trail a light stre-
ak instead of building one up ahead
itself, as it does when the flash is syn-
chronised with the first shutter curtain. In
this way a „more natural" image of the
photographic situation is produced!
Depending on its operating mode, the
camera sets shutter speeds slower than
its sync speed.
On some cameras the REAR function is
not possible in certain operating modes
(e.g., certain vari- or subject programs,
or with red eye reduction). In these
cases, the REAR mode cannot be selec-
ted and/or is automatically cancelled or
ignored (see camera's operating instruc-
tions).
The REAR mode is set on the camera
(see camera's operating instructions).
There is no display for REAR mode in the
flash unit.

10.4 Slow synchronisation (SLOW)

A slow exposure (SLOW) gives added
prominence to the image background at
lower ambient light levels. This is achie-
ved by adjusting the shutter speed to the
ambient light. Accordingly, shutter
speeds that are slower than the flash
sync speed (e.g., shutter speeds up to 30
sec.) are automatically adjusted by the
camera. Slow synchronisation is activa-
ted automatically on some camera
models in connection with certain
camera programs (e.g., a night shot
program, etc.), or it can be set on the
camera (see the camera's operating
instructions). No settings are necessary
on the flash unit, nor is there any display
for this mode.
Slow synchronisation SLOW is set on
the camera (see camera's operating
instructions)! Use a tripod when shoo-
ting with slow shutter speeds to avoid
blurred images!
