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

processing is roughly equal to the current shutter

will blink in the

shutter speed/aperture displays and photographs can

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.
