Depending on the type of camera and the
operating mode used, the ISO speed transmit-
ted to the mecablitz by the camera can deviate
from the speed of the loaded film. Flash expo-
sure will nevertheless be correct. Please do
not make any manual modifications. They may
impair a later automatic adaptation.
4.12 2nd curtain synchronisation (REAR)
Synchronisation with the shutter’s second curtain
(REAR) is particularly advantageous when shooting
moving objects that have their own source of light
with a slow shutter speed (slower than 1/30
second). Second-curtain synchronisation gives a
more realistic impression of movement because
the light streaks behind the light source instead of
building up in front of it.
If second-curtain synchronisation is selected the
mecablitz flash is not triggered the moment the
first shutter curtain opens, but a fraction of a
second before the second shutter curtain is start-
ing. If a slow shutter speed has been chosen, or in
the “bulb” mode with the corresponding aperture,
the existing ambient light level permits traces of
moving lights to be seen on the film (e.g. light trails
left by the lights of a car). As the flash is fired right
before the end of the exposure time, the moving
subject is frozen at the end of the light trail. The
effect thus achieved seems more natural to the
perception of the eye than pictures where the flash
was fired at the beginning of the exposure,
