Front and Rear-curtain Synchronization
Some cameras offer the option of rear curtain synchronization
(Rear mode) that triggers the flash unit at the end of the
exposure time. Rear curtain synchronization is particularly
advantageous when using slow shutter speed (slower than
1/30 sec.) or when shooting moving objects that has their
own source of light. Rear curtain synchronization 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 synchronized
with the front shutter curtain.
For Type P: Select the synchronization mode as front
curtain or rear curtain at the back of the flash. The flash
will fire according to the mode selected to match with the
camera shutter.
For Type C, N, O and S: The camera controls front or
rear-curtain synchronization, therefore no setting is
required to be done on the flash.
Note: Rear curtain synchronization is only possible on
cameras with this feature. See your camera’s
instruction manual for details.
