7.4 Automatic high-speed synchroni-
sation (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-
speed synchronisation in E-TTL and M flash
modes.
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 synchro-
nisation is activated automatically if a shut-
ter speed faster than the flash sync speed is
set on the camera, whether manually or auto-
matically 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!
