Nikon Long Exposure NR, High ISO NR, (Long Exposure Noise Reduction)

Long Exposure NR

(Long Exposure Noise Reduction)

Gbutton ➜ Cshooting menu

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; during processing, “l m” will flash in the shutter speed/aperture displays 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. Long exposure noise reduction is not available during movie recording.

High ISO NR

Gbutton ➜ Cshooting menu

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

Option	Description
High	Reduce noise (randomly-spaced bright pixels, lines, or fog), particularly in
Normal	photographs taken at high ISO sensitivities. Choose the amount of noise reduction
	performed from High, Normal, and Low.
Low
	Noise reduction is only performed at ISO sensitivities of ISO 1250 and higher. The
Off	amount of noise reduction is less than the amount performed when Low is selected
	for High ISO NR.
