I found an MS link that has other interesting links for those who would like
to know more of the technology.
http://www.microsoft.com/whdc/device/display/color/icmwp.mspx?pf=true#icmfig2
Vista may have some new tricks when it comes to color matching.
I discovered that my Photoshop Elements has the ability to read the matching
tag on a Jpg one of the sites from the links has as a test tool. So, even if
my entire system is not complying, I at least know an important part is, my
main photo software.
