Automatic fill-in flash operation in the TTL operating modes
The automatic fill-in flash mode is activated by most cameras when the automatic
programme P is selected and by Vari or subject programmes during daylight
(see camera operating manual).
Fill-in flash mode overcomes troublesome shadows and produces a more balan-
ced exposure between subject and background with contre-jour shots. The
camera’s computer-controlled metering system sets the most suitable combination
of shutter speed, aperture and flash output.
Ensure that the contre-jour light source does not shine directly into the
lens, as this will interfere with the camera’s TTL metering system!
There is no setting or display for automatic fill-in flash in the flash unit.
7.2 Manual flash mode
In the manual flash mode M , the flash unit emits the full uncontrolled amount of
light if no partial light output has been selected. The specific photographic situa-
tion can be taken into account by adjusting the aperture setting or by selecting a
suitable manual partial light setting. The setting area ranges from P 1/1 to
P 1/128 in M mode and P1/1 - P1/32 in HSS mode (see 7.3). The display
shows the distance at which the subject is correctly lit (see 5.2).

TTL Manual partial light output levels
In manual flash mode set the partial light output desired with the buttons
( + ) and ( - ). The setting takes effect immediately and is saved automatically.
The distance display is adjusted to the partial light output automatically (see 5.2).
Various camera models support the manual flash mode only in the
camera mode manual M! In other camera models an error message
appears in the display and the release is locked!
7.3 Automatic high-speed synchronisation (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 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 TTL high-speed synchronisation in M flash
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 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!
