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 Exif 2.21 and 
DCF 2.0 compliant; applications and printers that support Exif 2.21 and 
DCF 2.0 will select the correct color space automatically. If the application 
or device does not support Exif 2.21 and DCF 2.0, select the appropriate 
color space manually. An ICC color profile is embedded in TIFF 
photographs taken in the Adobe RGB color space, allowing applications 
that support color management to automatically select the correct color 
space. For more information, see the documentation provided with the 
application or device.
Nikon Software
The following Nikon software automatically selects the correct color 
space when opening photographs created with the D300: ViewNX version 
1.2.0 or later, Capture NX version 1.3.5 or later (available separately), and 
Capture NX 2 version 2.1.0 or later (available separately).
