Supported Color Profiles

1. Standard RGB Profiles Supported in Nikon Capture 4

1.1 Profiles with a Gamma Value of 1.8

Apple RGB: NKApple.icm (Windows)/Nikon Apple RGB 4.0.0.3000 (Macintosh)

This profile is used in desk-top publishing applications and in Adobe Photoshop versions 4.0 or earlier, and is the typical RGB profile for Macintosh monitors. The corresponding RGB setting in Adobe Photoshop is “Apple RGB.” This profile is suitable for working with images displayed on the Macintosh.

ColorMatch RGB: MKCMatch.icm (Windows)/Nikon ColorMatch RGB 4.0.0.3000 (Macintosh) The ColorMatch profile 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 corre- sponding RGB setting in Adobe Photoshop is “Color Match RGB.”

1.2 Profiles with a Gamma Value of 2.2

sRGB: NKsRGB.icm (Windows)/Nikon sRGB 4.0.0.3001 (Macintosh)

This RGB profile 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 manufacturers use it as a default color profile and guarantee op- eration when it used. It is also on its way to becoming the standard for images on the web. This profile is suited to users who plan to use their digital images “as is,” without editing or printing 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 profile attempts to expand on the ColorMatch RGB gamut by defining the chroma- ticity for G as lying between the values for G in the Adobe RGB and ColorMatch color-space profiles. 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 profiles match.

NTSC (1953): NKNTSC.icm (Windows)/Nikon NTSC (1953) 4.0.0.3000 (Macintosh)

This is the color space for video defined 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).”
