6. Flash synchronisation
Different modes of flash synchronisation are pos-
sible, depending on the camera model. Please
refer to the camera’s operating instructions to find
out how the individual modes of synchronisation
are set on the camera.
6.1 Normal synchronisation
This mode is available with all TTL cameras, and it
is suitable for most flash shots. With normal
synchronisation, switching to the camera’s flash
sync shutter speed is automatic. The shutter
speed may vary from 1/30th and 1/300th seconds,
depending on the camera model. Please refer to
the camera’s operating instructions for further
details.
6.2 Slow-synchronisation
Some cameras feature specific exposure pro-
grams for slow-synchronisation.
Flash shots at low lighting levels and fast shutter
speeds (normal flash sync speed) can often result
in overexposed subjects in front of a very dark
back-ground. The slow-sync function allows the
use of slow shutter speeds right up to 30 seconds,
to significantly enhance the background as a result
of the extra ambient light. Such shots require a tri-
pod to prevent camera shake. Please refer to the
camera’s operating instructions for further details.
