Long Exp. NR

This option controls whether photographs taken at shutter speeds slower than about 1 s are processed to reduce “noise” (randomly-spaced, brightly-colored pixels that appear at slow shutter speeds, particularly in shadows). Highlight Long Exp. NR in the shooting menu ( 132) and press the multi selector to the right. Press the multi selector up or down to highlight an option, then press to the right to make a selection.
