If On is selected, photographs taken at shutter speeds slower
than 1 s will be processed to reduce noise (bright spots,
randomly-spaced bright pixels, or fog), increasing the time
required to record images by roughly 1.5 to 2 times.
During processing, “lm”
will blink in the viewfinder 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).
Photographs taken at high ISO sensitivities can be processed to reduce “noise.”

Noise reduction is only performed at ISO sensitivities of ISO 1600 and higher.

for High ISO NR.
