ISO Sensitivity Adjust ISO sensitivity ( 37). Noise Reduction Photographs taken at high sensitivities or at shutter speeds of 8s or slower can be processed to reduce "noise" in the form of mottling or randomly-spaced, brightly-colored pixels. Choose from the following options: Option On Off Description Photographs taken at ISO sensitivities over ISO 400 or at shutter speeds of about 8s or slower are processed to reduce noise. In continuous shooting mode, frame rates will slow and the capacity of the memory buffer will drop. (At shutter speeds of 8s or slower, "Job nr" will be displayed at the bottom of the viewfinder for a period of time equal to about onehalf to one times the current shutter speed. New photographs can be taken when "Job nr" clears from the display. Noise reduction will not be performed if the camera is turned off before processing is complete.) Noise reduction turns off at ISO sensitivities of 800 or less. Minimal noise reduction is still performed at ISO sensitivities over 800. Menu Guide/Shooting Options: The Shooting Menu 73

Description
On
Photographs taken at ISO sensitivities over ISO 400 or at shutter speeds of about 8s or
slower are processed to reduce noise.
In continuous shooting mode, frame rates will slow
and the capacity of the memory buffer will drop.
(At shutter speeds of 8s or slower, “Job nr”
will be displayed at the bottom of the viewfinder for a period of time equal to about one-
half to one times the current shutter speed. New photographs can be taken when “Job nr”
clears from the display.
Noise reduction will not be performed if the camera is turned off
before processing is complete.)

Noise reduction turns off at ISO sensitivities of 800 or less.
Minimal noise reduction is still
performed at ISO sensitivities over 800.
