6.4 Automatic high-speed synchronisa-
tion (HSS)
Various cameras support automatic high-
speed synchronisation (see the camera's
operating instructions). This flash mode
makes it possible to use a flash unit even
with shutter speeds that are faster than the
flash sync speed.
Interesting results may by achieved in this
mode when, for example, a wide open aper-
ture (e.g., f/2.0) is used to limit the depth of
field in portrait shots taken in very bright
ambient light. The flash unit supports high-
P TTL HSS
speed synchronisation in
mode.
For physical reasons, however, high-speed
synchronisation significantly reduces the
number and the maximum flash range.
Be sure to note, therefore, the flash range on
the display of the flash unit. High-speed syn-
chronisation is activated automatically if a
shutter speed faster than the flash sync
speed is set on the camera, whether manual-
ly or automatically by the exposure program.
Note that in the case of high speed synchro-
nisation the guide number of the flash unit
also depends on the shutter speed.
The faster the shutter speed, the lower the
guide number!
