13 Flash synchronisation

13.1 Automatic flash sync speed control

Depending on the camera model and camera
mode, the shutter speed is switched to flash
sync speed when flash readiness is reached
(see the camera's operating instructions).
Shutter speeds cannot be set faster than
the flash sync speed, or they are switched
automatically to the flash sync speed.
Various cameras have a sync speed range, for
example from 1/60 sec to 1/250 sec (see the
camera's operating instructions). The sync
speed set by the camera depends on the
camera mode, the ambient light, and the
focal length of the lens used.
Shutter speeds slower than the flash
sync speed can be set according to the
k camera mode and the selected flash
synchronisation.
If a camera with a between-the-lens shutter
and high-speed synchronisation (see 7.4) is
used, flash sync speed is not controlled
automatically. As a result, the flash can be
used at all shutter speeds. If you need the
full light output of the flash unit, you should
not select a shutter speed that is any faster
than 1/125 sec.

13.2 Normal synchronisation

In normal synchronisation the flash unit is
triggered at the beginning of the shutter
time (first curtain synchronisation). Normal
synchronisation is the standard mode on all
cameras. It is suitable for most flash shots.
The camera, depending on the mode being
used, is switched to the flash sync speed.
Speeds between 1/30 sec. and 1/125 sec.
are customary (see the camera's operating
instructions).
No settings are necessary on the flash unit,
nor is there any display for this mode.

13.3 Slow synchronisation (SLOW)

A slow exposure (SLOW) gives added promi-
nence to the image background at lower
ambient light levels. This is achieved by adju-
sting the shutter speed to the ambient light.
Accordingly, shutter speeds that are slower
than the flash sync speed (e.g., shutter
speeds up to 30 sec.) are automatically adju-
sted by the camera. Slow synchronisation is
activated automatically on some camera
models in connection with certain camera
programs (e.g., a night shot program, etc.), or
it can be set on the camera (see the camera's
operating instructions). No settings are
necessary on the flash unit, nor is there any
display for this mode.
