Bounced Flash; Bounced Flash With Activated Secondary Reflector; Bounced Flash In Automatic And Ttl Flash Modes - Metz MECABLITZ 60 CT-4 Manual De Instrucciones

• Turn on the flash unit with the main switch ¸ (fig 6).
• Turn the setting knob ¿ (fig. 4) on the flash head to set the film speed. The
white setting mark must be positioned opposite the ISO film speed rating.
Set the film speed also on the setting centre on the flashgun's handle.
• Push the locking key (fig. 3) downwards to unlock the setting centre.
• Turn the knurled knob (fig. 3) until "M" appears in the window.
• Push the locking key (fig. 3) upwards to lock the setting centre.
• Set the dial ³ (fig. 4) at MAN 1/8.
An f-number is now positioned opposite the indicated distance. This f-num-
ber is the aperture that has to be set.
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. 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.
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 Bounce flash with activated secondary reflector
The secondary reflector (Fig. 3) produces frontal fill-in light when the flash
is bounced.
The use of the secondary reflector is only expedient with bounce flash.
Switch turns the secondary reflector 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. 2.5, for the corresponding
procedure.
