If On is selected, photographs taken at
shutter speeds slower than 1 s will be
processed to reduce noise (bright spots
or fog). The time required for
processing roughly doubles; during
processing, “lm” will flash in the
shutter speed/aperture displays and
pictures can not be taken (if the camera
is turned off before processing is
complete, the picture will be saved but noise reduction will not
be performed).
In continuous release mode, frame rates will
slow and while photographs are being processed, the capacity
of the memory buffer will drop.
Photographs taken at high ISO sensitivities can be processed to
reduce “noise.”
