Nikon D90 user manual Color Space, Long Exp. NR Long Exposure Noise Reduction, 167, XAdobe RGB

Color Space

The color space determines the gamut of colors available for color reproduction. Choose a color space according to how photographs will be processed on leaving the camera. This option is available in all modes.

Option Description

WsRGB (default) Choose for photographs that will be printed or used “as is,” with no further modification.

XAdobe RGB	This color space is capable of expressing a wider gamut of colors than
	sRGB, making it the preferred choice for images that will be extensively
	processed or retouched.

AColor Space

Color spaces define the correspondence between colors and the numeric values that represent them in a digital image file. The sRGB color space is widely used, while the Adobe RGB color space is typically used in publishing and commercial printing. sRGB is recommended when taking photographs that will be printed without modification or viewed in applications that do not support color management, or when taking photographs that will be printed with ExifPrint, the direct printing option on some household printers, or kiosk printing or other commercial print services. Adobe RGB photographs can also be printed using these options, but colors will not be as vivid.

JPEG photographs taken in the Adobe RGB color space are DCF compliant; applications and printers that support DCF will select the correct color space automatically. If the application or device does not support DCF, select the appropriate color space manually. For more information, see the documentation provided with the application or device.

A Nikon Software	i
ViewNX (supplied) and Capture NX 2 (available separately) automatically select the correct
color space when opening photographs created with this camera.

Long Exp. NR (Long Exposure Noise Reduction)

Choose whether to reduce noise in pictures taken at slow shutter speeds. This option is available in all modes.

Option	Description
	Photographs taken at shutter speeds slower than 8 s
	are processed to reduce noise. The time required for
	processing is roughly equal to the current shutter
	speed; during processing, “l m” will blink in the
On	shutter speed/aperture displays and photographs can
	not be taken. In continuous release mode, frame rates
	will slow and the capacity of the memory buffer will
	drop. Noise reduction is not visible in pictures played
	back before processing is complete; noise reduction will not be performed if
	the camera is turned off before processing is complete.
Off (default)	Long exposure noise reduction off.
