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).
Setting procedure
• Press „Mode" until „ M " flashes in the display.
The setting takes effect immediately. After about 5 seconds the display stops
flashing and the setting is saved automatically. „

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.
