If the Resolution slider to
the left drops when you do this, see Chapter 5.
First, you??™ll need to gamma-correct your monitor, which helps ensure that
its brightness and color balance are optimized for your setup. Many higherend
monitors have gamma adjustment features, but barring that, you can
use the free QuickGamma utility (Figure 4-16), available at http://
quickgamma.de/indexen.html. (A similar utility also comes with Adobe Photoshop,
although the author of QuickGamma claims that it??™s more accurate.)
The process essentially involves adjusting a few controls until two different
grayish regions appear indistinguishable when you squint. If you??™re a perfectionist,
you should elect to adjust red, green, and blue values independently.
Next, open Control Panel and then Color Management. Each imaging
device on your system should be accompanied by a matching International
Color Consortium (ICC) profile, and the Color Management window,
shown in Figure 4-17, is where you manage these files.
Start with your monitor; select it from the Device list, and then click Add. If
you??™re lucky, you??™ll see a matching profile in the list (having been installed
with your driver); otherwise, you??™ll have to dig up the correct ICC profile
from the manufacturer of your monitor and then install it by clicking the
Browse button here.
If you have trouble finding ICC profiles from the manufacturers
of your monitor, scanner, printer, or camera, try a site like
