Supported Color Profi les
1. Standard RGB Profi les Supported in Nikon Capture 4
1.1 Profi les with a Gamma Value of 1.8
Apple RGB: NKApple.icm (Windows)/Nikon Apple RGB 4.0.0.3000 (Macintosh)
This profi le is used in desk-top publishing applications and in Adobe Photoshop versions 4.0
or earlier, and is the typical RGB profi le for Macintosh monitors. The corresponding RGB
setting in Adobe Photoshop is “Apple RGB.” This profi le is suitable for working with images
dis played on the Macintosh.
ColorMatch RGB: MKCMatch.icm (Windows)/Nikon ColorMatch RGB 4.0.0.3000 (Macintosh)
The ColorMatch profi le is native to Radius PressView monitors. It has a wider gamut than
Apple RGB, with a particularly wide area devoted to the reproduction of blues. The cor re -
spond ing RGB setting in Adobe Photoshop is “Color Match RGB.”
1.2 Profi les with a Gamma Value of 2.2
sRGB: NKsRGB.icm (Windows)/Nikon sRGB 4.0.0.3001 (Macintosh)
This RGB profi le is used in the majority of Windows monitors. It closely resembles the RGB
commonly used in color television, and is also used in the digital television broadcasting sys-
tem that is on its way to becoming the industry standard in the United States of America.
Software and hardware man u fac tur ers use it as a default color profi le and guarantee op-
er a tion when it used. It is also on its way to becoming the standard for images on the web.
This profi le is suited to users who plan to use their digital images “as is,” without editing or
print ing them. It however suffers from the drawback of a narrow gamut with a limited area
available for reproducing blues. The corresponding RGB setting in Adobe Photoshop 5.0 and
5.5 is “sRGB,” the corresponding setting in Adobe Photoshop 6.0 “sRGB IWC61966-2.1.”
Bruce RGB: NKBruce.icm (Windows)/Nikon Bruce RGB 4.0.0.3000 (Macintosh)
This color profi le attempts to expand on the ColorMatch RGB gamut by defi ning the chro ma -
tic i ty for G as lying between the values for G in the Adobe RGB and ColorMatch color-space
profi les. It was proposed by Bruce Fraser, who claims that it includes most of the colors in the
SWOP CMYK gamut. The R and B used in the Bruce RGB and Adobe RGB color-space profi les
match.
NTSC (1953): NKNTSC.icm (Windows)/Nikon NTSC (1953) 4.0.0.3000 (Macintosh)
This is the color space for video defi ned by the National Television Standards Committee (NTSC)
in 1953 and used in early color televisions. This color space is also used in some Far-East
newspaper and printing organizations. The corresponding RGB setting in Adobe Photoshop
is “NTSC (1953).”
