Long Exposure NR

Photographs taken at slow shutter speeds are automatically processed to reduce “noise” (bright spots, randomly-spaced bright pixels, or fog), slightly increasing recording times. Selecting On increases the amount of noise reduction performed at shutter speeds slower than 1 s and increases the time required to record images by roughly 1.5 to 2 times. During processing, a warning will be displayed and pictures can not be taken (if the camera is turned off before processing is complete, the picture will be saved but noise reduction will not be performed). In continuous release mode, frame rates will slow and while photographs are being processed, the capacity of the memory buffer will drop.
