Noise Reduction

Photographs taken at high sensitivities or at shutter speeds of 1s or slower can be processed to reduce “noise” in the form of mot- tling or randomly-spaced, brightly-colored pixels. Choose from the following options:

Option Description

On

Photographs taken at ISO sensitivities over ISO 800 or at shutter speeds of about 1s or slower are processed to reduce noise (if shutter speed is 1s or slower, time need to process photographs before they are recorded approximately doubles and capacity of memory buffer may drop). “Job nr” is displayed at the bottom of the viewfinder during processing. Noise reduction will not be performed if the camera is turned off before processing is com- plete.

Off Noise reduction turns off at ISO sensitivities of 1600 or less. Minimal noise reduction is still (default) performed when ISO sensitivity is set to HI 1.

Frame rates will slow if On is selected in continuous shooting mode ( 32).
