Supported Color Profiles

Adobe RGB (1998): NKAdobe.icm (Windows)/Nikon Adobe RGB (1998) 4.0.0.3000 (Macintosh) A color-space profile defined in Adobe Photoshop 5.0. It has a wider gamut than sRGB and includes the colors found in most CMYK gamuts, making it suitable for users involved in desk- top publishing. The corresponding RGB setting in Adobe Photoshop 5.0 is “SMPTE-240M,” the corresponding setting in Adobe Photoshop 5.5 or later “Adobe RGB (1998).”

CIE RGB: NKCIE.icm (Windows)/Nikon CIE RGB 4.0.0.3000 (Macintosh)

Avideo color-space profile established by the Commission Internationale de l’Éclairage (CIE). While it boasts a fairly wide gamut, it suffers from the drawback that the area devoted to the reproduction of cyan is relatively small. The corresponding RGB setting in Adobe Photoshop is “CIE RGB.”

Adobe Wide RGB: NKWide.icm (Windows)/Nikon Adobe Wide RGB 4.0.0.3000 (Macintosh) This color-space profile, designed by Adobe, incorporates most of the visible colors. This however has the consequence that most of the colors it can express can not be reproduced on standard monitors and printers. The corresponding RGB setting in Adobe Photoshop 5.0 or later is “Adobe Wide RGB.”

The gamut of colors that can be expressed in the above color-space profiles is shown in the following chromaticity (x, y) graph. The greater the area enclosed by the triangle that repre- sents the color-space profile, the wider its gamut.
