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). The time required for
processing roughly doubles; during processing, "l m" will flash in the viewfinder
and pictures can not be taken (noise reduction will not be performed if the camera is
turned off before processing is complete).
