Long Exposure Nr (Long Exposure Noise Reduction); High Iso Nr - Nikon D850 Menu Manual

Long Exposure NR (Long Exposure Noise Reduction)

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, "l m" will flash in the
shutter speed/aperture displays and
pictures cannot 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.

High ISO NR

Photographs taken at high ISO sensitivities can be processed to
reduce "noise".
Option
Reduce noise (randomly-spaced bright pixels), particularly
High/
in pictures taken at high ISO sensitivities. Choose the
Normal/
amount of noise reduction performed from High, Normal,
Low
and Low.
Noise reduction is performed only as required and never at
Off
an amount as high as when Low is selected.
