of f/4 has to be set on the camera. The adjusted aperture must be cor-
rected when the wide-angle diffuser is used.
5. Bounce 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 bounce 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 bounce 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 bounce 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.
5.1 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. 2.5, for the corresponding
procedure.
5.2 Bounce 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.
6. Winder/Motordrive Mode
Definition:
In the winder/motordrive mode a series of pictures can be shot at the rate of
several frames per second. The winder mode is based on partial light output
levels.
Up to 2 flashes per second can be fired in the "Winder W" mode; up to 5
flashes per second are possible in the "Motordrive MD" mode.
Setting procedure for picture shooting in the winder flash mode:
• Set the camera as described in its Operating Instructions.
• Turn on the flash unit by its main switch
• Turn the setting knob
(fig. 4) for film speed on the reflector head. The
setting mark must be positioned at the given ISO film speed.
• Set the setting dial ³ (fig. 4) at "W" or "MD"
The distance will then be opposite an f-number. This f-number is the apertu-
re to be set.
• Await flash readiness indication – The flash ready indicator
lights up.
The aperture to be set on the camera is then indicated on the scale opposi-
te the flash-to-subject distance.
