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 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”.
