5. Manual Flash Mode
In this mode the flashgun will emit its full power, provided that partial light
output (M1/2 - M1/4) has not been adjusted. The flashgun can be adapted
to the actual picture shooting situation by setting the corresponding aperture
on the camera.
If the displayed value does not coincide with the actual distance, then the
aperture and/or partial light output level (M1/2 and M 1/4) have to be
changed accordingly.
The decisive points for partial light output are:
• The distance to the subject
• The required aperture
• The ISO film speed
Adjusting procedure for the manual flash mode:
Example:
Flash-to-subject distance: 5 m
Film speed: ISO 100/21°
• 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 M.
The aperture to be adjusted is indicated on the scale above the given flash-
to-subject distance.
At a flash-to-subject distance of 5 m (as in our example), an aperture
of f/8 has to be set on the camera. The adjusted aperture must be cor-
rected when the wide-angle diffuser is used. The settings calculator
takes the wide-angle diffuser into account.

6. Bounced Flash
Photos shot with full frontal flash are easily recognizable by their harsh, den-
se shadows. This is often associated with a sharp drop of light from the fore-
ground to the background.
This phenomenon can be avoided with bounced flash because the diffused
light will produce a soft and uniform rendition of both the subject and the
background. For this purpose the main reflector is turned in such a manner
that the flash is bounced back from a suitable reflective surface (e.g. ceiling
or walls of a room).
For this reason the main reflector can be turned vertically and horizontally.
The following are the vertical lock-in positions for bounced flash:
• 15°, 30°, 45°, 60°, 75° and 90° (simply tilt the reflector to the required
angle)
The head can be swivelled horizontally to the left and right by 180°, and
locks into position at 90° and 180°.
When swivelling the reflector vertically, it is essential to ensure that it
is turned by a sufficiently wide angle so that direct light can no longer
fall on the subject. Therefore, always tilt the reflector to at least the 60°
lock-in position.
The diffused light bounced back from the reflective surfaces results in a soft
illumination of the subject.
The reflecting surface must be white or a neutral colour, and it must not be
structured (e.g. wooden beams in the ceiling) as this could cast shadows. For
colour effects just select reflective surfaces in the required colour.
Use of the secondary reflector is advantageous to avoid disturbing dense
shadows with bounced flash, for instance under the eyes and nose of por-
traits.
6.1 Bounced flash with activated secondary reflector
The secondary reflector ቧ produces frontal fill-in light when the flash is
bounced.
