If On is selected, photographs taken at
shutter speeds slower than 1 s will be
processed to reduce noise (randomly-spaced
bright pixels or fog). The time required for
processing is roughly equal to the current
shutter speed; during processing, “l m”
will blink 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.
High ISO NR has no effect on movies.
