range on the display of the flash unit. High-speed synchronisation is activated
automatically if a shutter speed faster than the flash sync speed is set on the
camera, whether manually or automatically by the exposure 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!
Setting procedure
• repeatedly press the„Mode“ ባ button until„E HSS“ or „ HSS“ flashes
in the display.
The setting takes effect immediately. After about 5 seconds the display stops
flashing and the setting is saved automatically. „E HSS“ or „ HSS“ is
shown in the display. High-speed synchronisation can be deleted by repeated-
ly pressing the „Mode“ button until the „HSS“ symbol disappears.
Second curtain synchronisation (REAR) is automatically deactivated when
the flash unit is set to high-speed synchronisation FP or HSS!
8 Manual flash exposure correction
The auto flash exposure mode of most cameras is adjusted to a reflection factor
of 25% (the average reflection factor of flash subjects). A dark background that
absorbs much of the light or a highly reflective bright background (backlit shots,
for example) may result in, respectively, underexposure or overexposure of the
subject.
To offset these effects, the flash exposure can be adjusted manually for the shot
with a correction value. The extent of the correction depends on the contrast bet-
ween the subject and background!
In TTL flash modes, manual flash exposure correction factors of from -3 EV
(f-stops) to +3 EV (f-stops) can be adjusted on the flash unit in one-third incre-
ments.

Tip:
Dark subject against light background: positive correction factor. Light subject
against dark background: negative correction factor.
Exposure correction by means of alteration of the lens aperture setting is
impossible, since the camera’s automatic exposure program regards the
altered aperture setting as the normal working aperture setting. When
setting the correction factor, the distance shown in the display can change
and be adjusted to the correction factor (depending on the camera
model)!
Setting procedure
• Press button ( - ) or ( + ) until „EV“ flashes. Apply the setting wished with the
buttons ( + ) and ( - ):
Set a negative correction factor with the button ( - ) or a positive one with the but-
ton ( + ).The setting takes effect immediately. After about 5 seconds the display
stops flashing and the setting is saved automatically. After saving, „EV“ appears
in the display with the correction value set in place of the aperture factor.
Press the button ( - ) or ( + ) until „EV“ without a correction factor is shown. The
setting takes effect immediately. After about 5 seconds the display stops flashing
and the setting is saved automatically. After saving the aperture factor appears
once again.
Manual flash exposure correction is only possible in TTL flash mode if the
camera supports this function (consult the camera’s operating instruc-
tions)! If the camera does not support this function, the adjusted correc-
tion will have no effect.
For some camera models, the manual flash exposure corrections must be adju-
sted on the camera. If this is the case, no correction value will appear on the
flash unit display.
After the shot, remember to cancel the TTL flash exposure correction in the
camera!
