User Guide
•
Apple RGB for the RGB color space used by
earlier versions of Adobe Photoshop as well as a
variety of other desktop publishing applications.
Apple RGB is a good choice for online images that
will be displayed on Mac OS systems.
•
CIE RGB for the RGB color space defined by the
Commission Internationale d’Eclairage. This
option provides a fairly large color gamut, but
does not handle cyan very well.
•
ColorMatch RGB for the RGB color space
defined by Radius that matches the native color
space of their Pressview monitors.
•
NTSC (1953) for the video color space defined
by the National Television Standards Committee
(NTSC). This is the original color television
standard. It has been mostly superseded by the
more recent SMPTE-C standard.
•
PAL/SECAM for the current color television
standard for Europe and other parts of the world
that use PAL or SECAM-based television.
•
SMPTE-240M for the RGB color space for high-
definition television production (as opposed to
broadcast). It has a larger color gamut than the
spaces based on HDTV phosphors. This option
can be a good choice if you need a wider color
gamut than many of the other color spaces—sRGB
in particular—without going to the extreme of
using Wide-Gamut RGB.
•
SMPTE-C for the current color television
standard in the United States and other parts of the
world that use NTSC-based television.
•
Wide-Gamut RGB for a very wide-gamut RGB
space defined using pure spectral-color primaries.
This space’s gamut includes almost all visible
colors and is wider than what the typical monitor
can display accurately. However, many colors
specified in the gamut cannot be reproduced on
RGB monitors or on press.
•
Custom to create a custom RGB profile. This
option may be useful if you know the description
of the RGB space for your scanner and you want to
set Photoshop’s RGB color space to be the same.
(For details see the instructions “To create a
custom RGB profile” later in this section.)
4 Select Display Using Monitor Compensation to
display images using the monitor’s RGB color
space. This does not affect the color information in
images, only the way images look on the screen,
and provides a more accurate display. Leaving this
option deselected displays images directly to the
monitor, with no compensation, and can make
screen updates faster but less accurate.
