DUELING GAMMAS?

The monitors of Apple Macintosh and Microsoft Windows computers are set to different

gammas at the factory. (Gamma is a measure of contrast.) Photographs look different on

the two systems.

Macintosh monitors are set to a gamma of 1.8, ideal for creating printed documents.

Windows monitors are set to a gamma of 2.2, the U.S. broadcast television standard. You

can prepare your Internet images on a monitor set with Adobe Gamma for a gamma of 1.8

or 2.2, or you can compromise and use a gamma of 2.0.

You can preview the effects of the gamma change. Choose View, Proof Setup, Windows

RGB to preview how the image will look on a Macintosh (see Figure 23.4) or View, Proof

Setup, Macintosh RGB to preview how the image will look on a Windows computer.
