Vignette Control

Gbutton ➜ Cshooting menu

“Vignetting” is a drop in brightness at the edges of a photograph. Vignette control reduces vignetting for type G, E, and D lenses (DX and PC lenses excluded). Its effects vary from lens to lens and are most noticeable at maximum aperture. Choose from High, Normal, Low, and Off.

AVignette Control

Depending on the scene, shooting conditions, and type of lens, JPEG images may exhibit noise (fog) or variations in peripheral brightness, while custom Picture Controls and preset Picture Controls that have been modified from default settings may not produce the desired effect. Take test shots and view the results in the monitor. Vignette control does not apply to movies (0 57), multiple exposures (0 160), or DX-format images (0 89).

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
	Low	performed from High, Normal, and Low.
		Noise reduction is only performed at ISO sensitivities of ISO 2500 and higher. The
	Off	amount of noise reduction is less than the amount performed when Low is selected
		for High ISO NR.
