Notes on RGB Profiles Provided with Nikon Scan
Apple RGB (gamma 1.8)
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 set-
ting in Photoshop 5.0 is "Apple RGB." This profile is suitable for
working with images displayed on the Macintosh.
ColorMatch RGB (gamma 1.8)
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 corresponding
RGB setting in Photoshop 5.0 is "Color Match RGB."
Reference: Preferences
Apple RGB (compensated) (gamma 1.8)
This profile defines tristimulus (red, green, and blue) chromatic-
ity as the intersection of the curve that marks the limits of the
visible gamut with lines drawn from the Apple RGB white point
and passing through the points that define tristimulus chroma-
ticity in the Apple RGB color-space profile. This profile is unique
in that it preserves the characteristics of Apple RGB while al-
lowing more saturated colors. It is not provided in the standard
install of Photoshop 5.0, but can be selected as the RGB color-
space profile for Photoshop by importing the profile
"NKApple_CPS.icm".
