Slow Synchronisation (Slow); Preflash Function For Red-Eye Reduction - Metz MECABLITZ 44 AF-1 digital Manual De Instrucciones

The REAR mode is set on the camera
(see camera's operating instructions).
There is no display for REAR mode in the
flash unit.

10.4 Slow synchronisation (SLOW)

A slow exposure (SLOW) gives added
prominence to the image background at
lower ambient light levels. This is achie-
ved by adjusting the shutter speed to the
ambient light. Accordingly, shutter
speeds that are slower than the flash
sync speed (e.g., shutter speeds up to 30
sec.) are automatically adjusted by the
camera. Slow synchronisation is activa-
ted automatically on some camera
models in connection with certain
camera programs (e.g., a night shot
program, etc.), or it can be set on the
camera (see the camera's operating
instructions). No settings are necessary
on the flash unit, nor is there any display
for this mode.
Slow synchronisation SLOW is set on
the camera (see camera's operating
instructions)! Use a tripod when shoo-
ting with slow shutter speeds to avoid
blurred images!
10.5 Preflash function for red-eye
reduction
The red-eye effect occurs when the per-
son being photographed is looking for
more or less straight into the camera, the
ambient lighting is poor, and the flash
unit is mounted close to the camera. The
flash unit then illuminates the interior of
the subject's eyes through the pupils.
Some camera models have a preflash
function for reducing the red-eye effect.
One or more preflashes induce the
pupils to contract more, thereby redu-
cing the red-eye effect.
On some cameras, the preflash function
supports only the camera's internal
flash unit or an illuminator incorporated
in the camera body.
The preflash function is set on the
camera (see the camera's operating
instructions)! Second curtain synchroni-
sation (REAR) is not possible when the
preflash function is used. There is no
setting or display for this mode on the
flash unit.
