Wide Gamut RGB (compensated)

Nikon scanners can scan some colors that cannot be ex-

pressed using the Wide Gamut RGB color-space proﬁ le.

The com pen sat ed Wide Gamut RGB proﬁ le redeﬁ nes Wide

Gamut RGB to include all the colors that can be output from

the scanner. Be cause many of the colors that can not be ex-

pressed in Wide Gamut RGB occur in the blue por tion of the

gamut, the level of detail in the blue area has been greatly

increased (be cause the gamut has been expanded in a non-

lin ear fash ion to in cor po rate just those colors that could not

otherwise be ex pressed, it can not be rep re sent ed in chro-

ma tic i ty di a grams using a stan dard RGB triangle). As is the

case with Wide Gam ut RGB, most of the colors deﬁ ned in

this proﬁ le can not be re pro duced on mon i tors and print-

ers. It is output to the host ap pli ca tion as Wide Gamut RGB.

When scanning images into Photoshop 5.0 using this proﬁ le,

set the Photoshop RGB proﬁ le to "Wide Gamut RGB."

Scanner RGB

This proﬁ le replicates the color space achieved when scan ning

with Nikon CMS off. Its main purpose is to allow the LCH

ed i tor and Unsharp Mask tools, which are not available when

Nikon CMS is off, to be used to edit the colors produced by

the scan ner. In order to pro duce the effect achieved by turn-

ing Nikon CMS off, the mon i tor proﬁ le is not used, nor is an

ICC proﬁ le included with the image when it is opened in the

host ap pli ca tion.
