Nikon D5100 Long Exposure NR, High ISO NR, l m

Long Exposure NR

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), increasing the time

required 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 off before processing is complete, the picture will be saved but noise reduction will not be performed).

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