Aperture Priority Mode A And Ttl Flash Operation; Shutter Speed Priority Mode T And Ttl Controlled Variable Flash Illumination - Leica R9 Bedienungsanleitung

Aperture priority mode A and TTL flash
operation
For "normal" flash photographs inside and gene-
rally for poor lighting conditions.
The aperture setting is selected according to the
flash unit's operating range and the desired
depth of field, while the shutter speed is automa-
tically set to 1/250 s by the camera. If this com-
bination would lead to overexposure due to the
available ambient light, the time display 2 2 5 5 0 0
(2.9 a) starts to flash. In this case, a smaller
aperture setting should be selected.
Shutter speed priority mode T and TTL con-
trolled variable flash illumination
For normal photographs with available light and
additional flash illumination.
All shutter speeds between 16 s and 1/250 s can
be freely selected, while the smallest aperture
should be manually set (e.g. 22). When a shorter
shutter speed is selected, the camera automati-
cally switches to the flash sync speed of
1/250 s. The aperture is set automatically by the
camera according to the available light, in order
to ensure correct exposure of the subject (even
without flash).
If this combination would lead to overexposure
due to the available ambient light, the time dis-
play 2 2 5 5 0 0 (2.9 a) starts to flash (also see „Impor-
tant" and „Notes" on p. 152).
The flash leads to additional TTL controlled illu-
mination. The flash illumination can be selective-
ly reduced on the SCA adapter or on the flash
unit itself (on SCA 3002 standard units) using
exposure compensation (e.g. – 2 EV) so that only
backlit shadows or subject details can be brigh-
tened. The natural lighting situation is retained.
