iGamma is an application which allows you to manage and create custom gamma levels for each of your programs. By creating profiles for each game, you are able to easily have unique settings depending on the application.

One of the best features of this program is that (unlike other programs), it does not require you to launch your game manually from within the application. iGamma will automatically detect when one of your games launches, and will load the appropriate gamma settings accordingly. Therefore, it is completely possible to use iGamma in combination with your favorite game-launcher, such as GameSpy.
