Noise Suppression Function For Long-Term Exposure; Shutter Type - Leica SL2 Instruction Manual

NOISE SUPPRESSION FUNCTION
FOR LONG-TERM EXPOSURE
Image noise becomes apparent when using higher sensitivities,
particularly on uniform dark areas. In order to reduce this annoying
phenomenon, the camera will take a second "black picture" (taken
with the shutter closed) automatically after pictures taken with
slow shutter speeds and high ISO values. The noise metered in this
parallel picture is then digitally "subtracted" from the data for the
actual picture. In such cases the message
will appear with a relevant time value. The doubling of the
"exposure" time must be taken into account for long exposure
times. The camera must not be switched off during that time.

SHUTTER TYPE

The Leica SL2 comes equipped with a mechanical shutter and a
purely electronic shutter function. The electronic shutter expands
the available shutter area and functions completely noiseless,
which may be important in some work environments.
