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 M-HSS mode. The display shows the
distance at which the subject is correctly lit (see 5.2).

7.3 Automatic high-speed synchronisation (FP or HSS)

Various cameras support automatic FP 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 high-speed synchroni-
sation in TTLand 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 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!
