Manual Exposure Setting; B Setting/T Function - Leica M9 Instructions Manual

Manual exposure setting

If the exposure setting is performed entirely manually,
the shutter speed setting dial (1.17) must be clicked to
one of the engraved shutter speeds or to one of the
intermediate values.
Then:
1. switch the exposure meter on and
2. turn the shutter speed setting dial and/or the aper-
ture setting ring on the lens (1.14) – in each case in
the direction indicated by the triangular LED that is
lit up – until only the circular LED is lit up.
As well as the direction of rotation of the shutter
speed setting dial and aperture setting ring necessary
for correct exposure, the three LEDs in the light bal-
ance also indicate underexposure, overexposure and
correct exposure in the following way:
Underexposure by at least one stop; turning to
the right is required
1
• Underexposure of / stop; turning to the right
2
is required
• Correct exposure
1
• Overexposure of / stop; turning to the left is
2
required
Overexposure by at least one stop; turning to
the left is required
Note:
For shutter speeds longer than 2 s the remaining shut-
ter speed is counted down and displayed in seconds
after the shutter release.
140 / Manual exposure setting / B setting / T function
B setting / T function
The B setting keeps the shutter open for as long as
the shutter release button remains pressed (up to a
maximum of 240 s).
In conjunction with the self timer, a T function is also
B
available: If you set and activate the self timer by
tapping the shutter release button (see also p. 157),
the shutter opens automatically after the selected
delay time. It then remains open until you press the
shutter release button a second time – you do not
need to hold the button down. This enables you to
largely prevent any blurring caused by pressing the
shutter release button, even with long exposures.
In both cases, the exposure meter is disabled; after
the shutter is released however, the digital display in
the viewfinder shows the expired time in seconds for
guidance.
Notes:
• Long exposures can be associated with very heavy
picture noise.
• To reduce this annoying phenomenon, following pic-
tures with longer exposures (from around
fering depending on the other menu settings), the
LEICA M9 automatically takes a second "black pic-
ture" (taken with the shutter closed). The noise
measured in this parallel picture is then digitally
"subtracted" from the data set for the real picture.
• This doubling of the "exposure" time must be
allowed for with long exposures. The camera should
not be switched off during this time.
• For shutter speeds above 2 s, the message Noise
reduction in progress 12 s 1
appears in the monitor.
