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.
5.1 Fill-in flash in auto mode
Use the camera, or a hand-held exposure meter, to esta-
blish the required aperture and shutter speed for a normal
exposure.
Ensure that the camera's shutter speed either equals, or is
slower than, the fastest flash synch speed (varies with dif-
ferent 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 your 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 advisab-
le 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
recommend an aperture of f/5.6 to be set on the flashgun.
Tip:
If the auto-working aperture f/5.6 is not available on the
flash unit because of the adjusted film speed, then the pro-
blem can be overcome in the following manner:
Select an auto-working aperture of f/8 on the mecablitz
and set a shutter speed of 1/30th sec. and f/11 on the
camera.
If an auto-working aperture of f/4 were to be set on the
mecablitz, then a camera aperture of f/5.6 would result in
a shutter speed of 1/125th sec. This would fall short of the
camera's flash synch speed of 1/100th sec.
When shooting into the light ensure that the
backlight does not shine directly onto the sen-
sor as this will confuse the flashgun's electro-
nics.
