Operation Manual

Flash mode / 145
Notes:
• The settings and functions described in the follow-
ing sections relate exclusively to ash units that are
system compatible with the Leica M9.
• An exposure compensation set on the camera (see
p. 137) only inuences the measurement of availa-
ble light. If you want to simultaneously use compen-
sation of the TTL ash exposure metering in ash
mode – in parallel or in the opposite direction, you
must make this additional setting (on the ash unit).
• More details of ash use, in particular for other
ash units not specially designed for the Leica M9
and for dierent ash modes, can be found in the
relevant user guides.
SETTINGS FOR CAMERA-CONTROLLED
AUTOMATIC FLASH MODE
Once the ash unit you are using has been switched
on and set to the operating mode for GNC (= Guide
Number Control), the following actions on the Leica M9
are necessary:
1. Before taking each ash picture, rst switch on
exposure metering by lightly pressing the shutter
release button, i.e. the display in the viewnder
must switch to the shutter speed values or the
light balance. If this stage is missed out by fully
depressing the shutter release button in one quick
movement, the ash unit may not re if required.
2. Set the shutter speed setting dial to A , set the ash
sync speed (
1
/
180
s), or – for special eects – a
slower shutter speed (including B ). In aperture
priority mode the camera automatically switches to
the ash sync speed set in the menu, or to the time
range (see “Selecting the sync speed/the sync
speed range”, p. 147).
3. Set the desired aperture or the aperture required
for the distance to the subject.
Note:
If the automatically controlled (see “Flash mode”,
p. 144) or manually set shutter speed is faster than
1
/
180
s, the ash will not be red.
FLASH DISPLAYS IN THE VIEWFINDER WITH
SYSTEM-COMPATIBLE FLASH UNITS
A ash-shaped LED (2.1.3) appears in the Leica M9
viewnder as conrmation and to display the various
operating conditions. This LED appears together with
the displays for available light exposure metering,
described in the relevant sections.
