Exposure Control; Exposure Preview - Leica Q2 Instruction Manual

Notes
• Image noise becomes more apparent when using higher sensitivi-
ties, particularly on uniform dark areas. Long exposure times may
cause severe image noise. In order to reduce this annoying phe-
nomenon, the camera will take a second "black picture" (taken
with the shutter closed) automatically after a shooting with slow
shutter speed and high ISO value. The noise metered in this paral-
lel image is then digitally "subtracted" from the data for the actual
image. In such cases the message
will appear with a relevant time value. The doubling of the "expo-
sure" time must be taken into account for long-term exposure
times. The camera must not be switched off during that time.
• The maximum selectable shutter speed depends, among other
things, on the setting of the menu item
p. 95. The T function is available only if
to or .
Off Extended
• The remaining exposure time after shutter release is counted
down in seconds on the display for shutter speeds greater than
1 s.

EXPOSURE CONTROL

EXPOSURE PREVIEW

The brightness of the screen image mirrors the effects of the selected
exposure settings when pressing and holding the shutter button on
the first pressure point. You can now assess and control the effect of
the relevant exposure setting on the image before taking the picture.
This will apply as long as the subject brightness and the set exposure
don't result in excessively low or high brightness values.
This function can be disabled for the manual exposure setting (M).
Factory setting:
P-A-S-M
▸ Select in the main menu
Exposure Preview
▸ Select (only in automatic, aperture priority and shutter
P-A-S
speed priority mode) or
P-A-S-M
Notes
• Depending on ambient lighting conditions, the brightness of the
screen image may differ from that of the actual pictures, despite
the settings described above. The screen image will appear con-
siderably darker than the – correctly exposed – picture. That is
particularly the case in long-term exposures.
• The exposure preview will also be displayed if exposure metering
is done via another control element (e.g. using the Zoom/Lock
button, provided is was assigned the
(also for manual setting)
function).
