Values Above And Below The Metering Range - Leica M-P Instructions Manual

Notes:
• Long exposure times can be associated with very heavy picture
noise.
• To reduce this annoying phenomenon, following exposures with
slower shutter speeds (below approx.
on other menu settings) the Leica M/M-P automatically takes a
second "black picture" (with the shutter closed). The noise
present in this parallel picture is then digitally "subtracted" from
the data for the real picture.
This doubling of the "exposure" time can be significant at longer
exposure times, and must be allowed for. During this time the
camera should not be turned off.
• At shutter speeds of more than 2s, the message
appears in the monitor.

VALUES ABOVE AND BELOW THE METERING RANGE

If the exposure meter reading is below its working range in very low
lighting conditions and in manual mode, the left hand triangular
LED (( ) flashes as a warning in the viewfinder, while the right hand
LED ( ) does the same if there is too much light. In aperture
priority mode, the shutter speed is still displayed. If the required
shutter speed is more than the slowest possible 60s or less than
the fastest possible / s, these displays also flash. As the
1
4000
exposure is metered with the working aperture, this situation can
come about by stopping down the lens. Even if you are below the
metering range, the exposure meter remains on for around 30s
after you let go of the shutter release button. If the lighting
conditions improve in this time (e.g. through a change in the
subject detail or opening of the aperture), the LED display changes
from flashing to continuously lit, indicating that the meter is ready.
