RGB Profi les Provided with Nikon Scan
Windows Profi les (Gamma 2.2)
sRGB
This RGB profi le is used in the majority of Windows mon-
i tors. It closely re sem bles the RGB commonly used in color
tele vi sion, and is also used in the digital tele vi sion broad-
casting sys tem that is on its way to becoming the industry
standard in the United States of Amer i ca. Soft ware and
hardware man u fac tur ers use it as a default color profi le and
guarantee operation when it used. It is also on its way to
be com ing 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 printing them. It however suffers from
the draw back of a narrow gamut with a limited area avail-
able for re pro duc ing blues. The cor re spond ing RGB setting
in Photoshop 5.0 is "sRGB."
Bruce RGB
This color profi le attempts to expand on the ColorMatch
RGB gamut by de fi n ing the chromaticity for G as lying be-
tween the values for G in the Adobe RGB and ColorMatch
color-space pro fi les. It was pro posed by Bruce Fraser, who
claims that it in cludes most of the colors in the SWOP CMYK
gamut. It is not provided in the standard install of Photoshop
5.0, but can be selected as the RGB color-space profi le for
Photoshop by im port ing the profi le "NkBruce.icm".

toshop 5.0 is "Ado be RGB (1988)."
CIE RGB

small. The cor re spond ing RGB setting in Photoshop 5.0 is
"CIE RGB."

set ting in Photoshop 5.0 is "Wide Gamut RGB."
