Manual partial light output levels
Partial light output can be set in manual flash
mode.
Setting procedure
• Use the buttons to set the desired partial
light output (P). The distance information is adju-
sted according to how the partial light output is
set.
The setting is immediately effective and automati-
cally saved.
The distance display is adjusted to the partial light
output automatically (see 5.2).
7.5 Automatic high-speed synchronisation
(HSS)
Various cameras support automatic high-speed syn-
chronisation (see the camera’s operating instructi-
ons). 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 aperture (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
and flash modes.
For physical reasons, however, high-speed synchro-
nisation 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 synchronisati-
on is activated automatically if a shutter speed
faster than the flash sync speed is set on the came-
ra, whether manually or automatically by the expo-
sure program.
Note that in the case of high speed synchronisation
the guide number of the flash unit also depends on
the shutter speed.
The faster the shutter speed, the lower the guide
number!
