5.9 Preflashes for red-eye reduction
Red eyes are always the result of a physical effect.
It arises whenever a person looks more or less
straight into the camera , the ambient light is rela-
tively dark, and the flash unit is mounted on or
directly next to the camera. The flash unit illumi-
nates the back of the eyes, revealing the blood-
filled retina through the pupil. This is recorded by
the camera as a red spot in the eyes.
The red-eye reduction facility brings about a sig-
nificant improvement in this respect. When this
function is used, the mecablitz triggers three
weakly visible preflashes prior to shutter opera-
tion, which are followed by the main flash. These
preflashes induce the pupils to close down, there-
by diminishing the red-eye effect.
The preflash function is set on the camera. An
activated preflash function is indicated on the
camera’s LC display by a corresponding symbol
(see operating instructions of the camera). There
is no setting made on the mecablitz, nor an in-
formation given on the mecablitz display.
The preflash function for red-eye reduction
is only possible with cameras that support
this mode (see Table 1)!
On some cameras, the red-eye reduction
will only support the flash unit built into the
camera or an extra illuminator incorpo-
rated in the camera body (see operating
instructions of the camera)!
2nd curtain synchronisation (REAR) will not
work when the preflash function is used!
5.10 Return to basic setting
The mecablitz returns to its basic setting when the
“Mode” key is kept depressed for at least three
seconds.
The following settings are adjusted:
• The “TTL” flash mode.
• The “Auto-OFF” (3m On) function is activated.
• The automatic zoom mode “Auto Zoom”.
• The extended-zoom mode “Ex” is cancelled.
• The flash exposure correction value on the
mecablitz (44 AF-4N) is cancelled.
• The REAR function on the mecablitz is deacti-
vated.
