Bounce Flash - Metz MECABLITZ 70 MZ-4 Manual De Instrucciones

Setting partial light output:
Partial light output can be set on the mecablitz if you wish to change the
distance range given for correct flash exposure in order to adapt it to the
existing picture-shooting situation:
• Continue turning the setting disk until the arrow symbol appears next to P
on the display.
• Push the setting disk in the direction of the arrow. The arrow symbol starts
flashing.
• Turn the setting disk to set the required partial light output level. Press the
setting disk in the direction of the arrow for storage. The selected partial
light output will be automatically stored after approx. 5 seconds if the set-
ting disk is not pressed. After storage the arrow symbol stops flashing.
Another possibility to modify the distance range for adaptation to the indivi-
dual picture shooting situation is to change the aperture on the camera. You
must, however, take into account that a change of the camera's aperture also
influences the picture's depth-of-field.
Deleting the set partial light output:
• Turn the setting disk until the arrow symbol appears next to P on the dis-
play.
• Push the setting disk in the direction of the arrow. The arrow symbol starts
flashing.
• Turn the setting disk to select partial light output P 1/1. Push the setting disk
in the direction of the arrow for storage. Storage is automatic after 5 se-
conds if the setting disk is not pressed. The arrow symbol will stop flashing
after storage. The partial light output is set to P 1/1 when changing to
another flash mode.

6. Bounce flash

Photos shot with full frontal flash are easily recognized by their harsh, dense
shadows. This is often associated with a sharp drop in 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 situation the reflector is turned in such a manner that
the flash is bounced off a suitable reflective surface (e.g. ceiling or walls of
the room).
The reflector can be turned vertically and horizontally.
The reflector head is mechanically interlocked in its basic position. Press the
pushbutton to unlock and turn the reflector head.
When turning the reflector vertically or horizontally, it is essential to
ensure that it is moved by a sufficiently wide angle so that direct light
can no longer fall on the subject. Consequently, always turn the reflec-
tor at least to the 60° lock-in position.
The distance readings on the LC display will disappear. The flash-to-
subject distance via the ceiling or wall is an unknown magnitude.
The light bounced off the reflecting surfaces produces a soft and uniform illu-
mination of the subject.
The reflecting surface must be white or have a neutral colour, and it must not
be structured, e.g. wooden beams in a ceiling, as these might cast shadows.
For colour effects just select the reflective surface in the desired colour.

Use the secondary reflector to avoid disturbing dense shadows that are
formed by bounce flash, for instance under the nose and in the eye sockets
for portraiture.
