The use of the secondary reflector is only expedient with bounced
flash.
Switch turns the secondary reflector ቧ on and off.
When the secondary reflector is activated, 85% of the light will be emitted by
the main reflector, and approx. 15% by the secondary reflector. The quoted
percentages may vary somewhat when flash with partial light output is adju-
sted, and the secondary reflector switched on.
Light output can be reduced with a light reducing filter by approx. 40%. For
this purpose place the reducing filter over the secondary reflector and press
both sides firmly until the filter audibly clicks into position.
6.2 Bounced flash in automatic and TTL flash modes
It is advisable to check prior to the actual exposure whether the light is suffi-
cient for the selected aperture. Please refer to Ch. 9, page 48, for the corre-
sponding procedure.
6.3 Bounced flash in manual flash mode
The required camera aperture in the manual flash mode is best established
with an exposure meter. Observe the following rule of thumb if an exposure
meter is not available
guide number
Camera aperture = —————————
light distance x 2
to establish the guide value for the aperture that can then be varied by +1 f-
stop for the actual exposure.
☞ 7. Winder Mode
Definition:
The winder mode involves shooting a sequence of pictures at a rate of several
frames per second. The winder mode uses partial light output levels (M 1/40).
Up to 2 flashes per second can be fired in this mode.
Adjusting procedure to work in winder flash mode
• Adjust the camera according to the manufacturer’s operating instructions.
• Turn the adjusting knob for film speed
ተ until the white marker is positio-
ned opposite the ISO film speed.
• Switch on the flashgun with the main switch ቪ.
• Set the selector dial to W.
• Wait for flash readiness
ቩ - the green LED lights up.
The aperture to be set on the camera can be read off the scale, opposite the
flash-to-subject distance.
Winder mode is only possible with a NiCad battery or Power Pack.
8. Fill-in Flash in Daylight
The mecablitz can also be used for fill-in flash in daylight to soften harsh sha-
dows and lower the contrast, thereby producing a more balanced exposure
when shooting against the light. Various possibilities are open to the user for
this purpose.
8.1 Fill-in flash in automatic 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 the given camera model).
Example:
Established aperture = f/8; established shutter speed = 1/60 sec. Flash
synch speed of the camera, e.g. 1/100 sec. (see operating instructions for
