The distance to the moving subject is used as the distance value. To
prevent overexposure of the motionless background this should
either be very dark or far behind the moving subject. The best results
are achieved at a low ambient light level.
Table 5 of the Technical Data specifies the maximum partial light output levels for
the N - f(Hz) combinations.
Ensure that an adequately slow shutter speed is set on the camera.
Table 6 of the Technical Data specifies the fastest shutter speeds for the N - f(Hz)
combinations.

11. Fill-in flash in daylight
Fig. 20: Fill-in flash in daylight
The mecablitz can also be used for fill-in flash in daylight to soften harsh shadows
and lower the contrast, thereby producing a more balanced exposure when
shooting against the light. Various possibilities are open to the user for fill-in flash.
Fill-in flash in auto mode
Use the camera, or a hand-held exposure meter, to establish the required aperture
and shutter speed for a normal exposure. Ensure that the shutter speed either equals,
or is slower than, the fastest flash synch speed (varies with different camera models).
Example:
Established aperture = f/8; established shutter speed = 1/60th sec.
Flash synch speed of the camera e.g. 1/100th sec. (see operating instructions for
the given camera).
The two established values for aperture and shutter speed can be set on the
camera because the camera’s shutter speed is slower than the camera’s flash
synch speed.
To maintain a balanced range of highlights, for instance in order to retain the
character of the shadows, it is advisable to select the automatic aperture on
the flashgun one setting lower than the aperture adjusted on the camera. In
our example f/8 was set on the camera. Consequently, we advise you to adjust
f/5.6 as the aperture setting on the flashgun.
