with color in general.
In Photoshop v7.0 (or later versions) go to EDIT >
COLOR SETTINGS
In the WORKING SPACES area go to the RGB dialog
box and select ColorMatch RGB.
In the CMYK dialog box, click on LOAD and then
choose the selection that says U.S. Web Coated (SWOP)
v2. If you are going to be doing a lot of CMYK work,
this will probably need to be changed to something that
more closely matches the lithographer’s presses that you
will have to interface with. Your lithographer should be
consulted.
In the GRAY dialog box, set it to GRAY GAMMA 1.8.
That is a standard, catch-all, setting.
In the area called COLOR MANAGEMENT
POLICIES, set CMYK and GRAY dialog boxes to OFF.
Set the RGB dialog box to CONVERT TO WORKING
RGB. Be sure ASK WHEN OPENING is checked.
Then, when ever you open a image that has never been
SAVED in PhotoShop, the system will ask you if you
want to convert the image to the current color space. In
most cases, you will answer YES, and have the image
converted to the current RGB color space which will be
ColorMatch RGB.
A brief note about some of the other options that are
available for the RGB setting:
sRGB - This color space was designed as an ―average PC monitor‖ RGB space for the World Wide Web. sRGB is a
useful lowest-common-denominator output space for Web and multimedia images, which will be displayed on monitors
of unknown characteristics. It is a good, catch-all, setting. (I just prefer ColorMatch RGB)
AppleRGB - This is basically the PhotoShop v2.0 default space. It is based on an Apple 13-inch RGB monitor and has a
slightly wider gamut than sRGB. However, its 1.8 gamma is not perceptually uniform, so it tends to posterize shadows
more quickly than sRGB.
CIE RGB - Has a very wide gamut – the primaries are all at the limit of human vision. That makes it unsuitable for
work using 8-bit channels, because posterization will almost inevitable result. It also does a rather poor job of reproducing
blue which goes black very quickly.
ColorMatch RGB is a special setting that is defined by Radius and matches the native color space of their Pressview
monitors that are used with APPLE computers. It could safely be called a safe choice for print work.
NTSC - For many years NTSC was the standard for broadcast video in North America. It has a wide gamut and a very
yellow white point. If you’re working on images for broadcast video, NTSC is a rational choice.
PAL/SECAM - This is the standard for broadcast video in Europe and much of Asia.
SMPTE-240M - This is a proposed RGB space for HDTV (high-definition television).
SMPTE-C - The current US broadcast video-production standard.
