to be seen (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 begi-
ning of the exposure, arresting the subject at the
beginning of its movement and light trail.
For the mecablitz 45 CL-4 digital flash mode
the connecting cable SCA 3045 (optional
extras) is necessary! The mecablitz 45 CL-4
digital supports flash exposure corrections
and second curtain synchronisation (REAR)
only if these can be set on the camera!
When using the REAR mode, mount your
camera on a tripod to avoid camera shake
with slow shutter speeds! Do not forget to
switch off this function after shooting, other-
wise an unwanted slow shutter speed could
result in camera shake with „normal" flash
shots.
Second-curtain synchronisation is not possi-
ble when the preflash function for red-eye
reduction or the 3D multi-sensor fill-in flash
mode have been activated. Should this be the
case, deactivate the function concerned.

6.10.3 Slow synchronisation

In certain operating modes, various cameras per-
mit slow flash synchronisation which will provide
added prominence 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
(e.g. shutter speeds up to 30 sec.) are automatical-
