154iIf On is selected, photographs taken at shutter speeds slowerthan 1 s will be processed to reduce noise (bright spots,randomly-spaced bright pixels, or fog), increasing the timerequired to record images by roughly 1.5 to 2 times. During processing, “l m”will blink in the viewfinder and pictures can not be taken (if the camera is turned offbefore processing is complete, the picture will be saved but noise reduction will notbe performed).Photographs taken at high ISO sensitivities can be processed to reduce “noise.”Long Exposure NR G button ➜ C shooting menuHigh ISO NR G button ➜ C shooting menuOption DescriptionHigh Reduce noise (randomly-spaced bright pixels, lines, or fog), particularly inphotographs taken at high ISO sensitivities.
