302UIf On is selected, photographs taken atshutter speeds slower than 1 s will beprocessed to reduce noise (bright spots,randomly-spaced bright pixels, or fog). Thetime required for processing roughly doubles;during processing, “l m” will flash in theshutter speed/aperture displays and picturescan not be taken (if the camera is turned off before processing iscomplete, the picture will be saved but noise reduction will not beperformed). In continuous release mode, frame rates will slow andwhile photographs are being processed, the capacity of thememory buffer will drop.Photographs taken at high ISO sensitivities can be processed toreduce noise.Long Exposure NR(Long Exposure Noise Reduction) G button ➜ C shooting menuHigh ISO NR G button ➜ C shooting menuOption DescriptionHigh Reduce noise (randomly-spaced bright pixels or fog),particularly in photographs taken at high ISO sensitivities.Choose the amount of noise reduction performed from High,Normal, and Low.NormalLowOffNoise reduction is performed only at sensitivities of 3200 andhigher. The amount of noise reduction is less than the amountperformed when Low is selected for High ISO NR.
