Operation Manual

7.2.2 REAR - Second-curtain synchronisation
Some cameras offer the facility of second-curtain synchronisa-
tion (REAR mode) triggering the mecablitz by the end of the
exposure time. Second-curtain synchronisation is particularly
advantageous when using slow shutter speeds (slower than
1/30 sec.) or when shooting moving objects that have their
own source of light. Second-curtain synchronisation gives a
more realistic impression of movement because the light stre-
aks behind the light source instead of building up in front of it,
as is the case when the flash is synchronised with the 1st shut-
ter 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 prominen-
ce 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 cameras
automatically activate SLOW synchronisation in connection
with certain programs (e.g. aperture priority “Av” or “A”,
night shots program, etc.) or permit slow synchronisation to
be set (see camera’s instruction manual).
Use a tripod to avoid camera shake with slow shutter
speeds!
