5 Flash modes
5.1 TTL- flash mode with measuring
preflash
The TTL flash mode with measuring pre-
flash is a further development of the
standard TTL flash mode of analogue
cameras. During the shot and before the
actual exposure, one or more almost
indiscernible preflashes are executed by
the flash. The light reflected by the
preflash is evaluated by the camera.
According to the evaluation, the subse-
quent flash exposure will be adjusted by
the camera to suit the situation (see the
camera's operating manual).
Depending on the camera model, the
preflashes precede the main flash by
such a short interval that they practical-
ly cannot be distinguished from the
main flash! The preflashes do not con-
tribute to the lighting of the shot.
Configuration procedure
• Switch on the flash unit by pressing the
button
.
• Press the "TTL"
button on the flash
unit to configure the TTL mode.
• Set a corresponding operating mode
on the camera e.g. P, A, S.
• Lightly depress the camera shutter to
allow the data transfer between
camera and flash unit.
If the camera supports TTL flash mode
with measuring preflash this will also be
carried out by the flash unit.
There is no special display for these flash
mode.
5.1.1
Automatic TTL– Fill-in flash mode
The automatic TTL flash mode is activated by
most cameras when the automatic program-
me P is selected and by Vari or subject pro-
grammes during daylight (see camera opera-
ting manual).
Fill-in flash mode overcomes troubleso-
me shadows and produces a more bal-
anced exposure between subject and
background with contre-jour shots.
