If On is selected, photographs taken at shutter 
speeds slower than 1 s will be processed to 
reduce noise (bright spots, randomly-spaced 
bright pixels, or fog). The time required for 
processing roughly doubles; the message 
shown at right will be displayed when 
processing starts and pictures can not be taken until processing is 
complete (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. Long exposure noise reduction is not 
available during movie recording.

Photographs taken at high ISO sensitivities can be processed to 
reduce “noise.”

Reduce noise (randomly-spaced bright pixels, lines, or fog), 
particularly in photographs taken at high ISO sensitivities. 
Choose the amount of noise reduction performed from High, 
Normal, and Low.

Noise reduction is only performed at ISO sensitivities of ISO 
1600 and higher. The amount of noise reduction is less than 
the amount performed when Low is selected for High ISO NR.
