Long Exposure NR G button ➜ C (photo shooting menu) 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, the message "Performing noise reduction" will be displayed, "Job NR" will flash in the control panel, and pictures cannot be taken (if the camera is turned off before processing is complete, the picture will be saved but noise reduction will not be performed). High ISO NR G button ➜ C (photo shooting menu) Photographs taken at high ISO sensitivities can be processed to reduce "noise". Option Description High/ Normal/ Low Reduce noise (randomly-spaced bright pixels), particularly in pictures taken at high ISO sensitivities. Choose the amount of noise reduction performed from High, Normal, and Low. Off Noise reduction is performed only as required and never at an amount as high as when Low is selected.
