Adobe Gamma is a control panel utility in Mac OS and Windows. It is used to calibrate and characterize your monitor, resulting in the creation of an ICC monitor profile for use in Photoshop 5.x, InDesign, Illustrator, and all other ICC-aware applications.
Monitor Calibration and Characterization Calibrating and characterizing your monitor is the first step in any color-managed workflow. Calibration is the process of adjusting a device to a known set of conditions by setting the monitor's gamma and a known white point. (In simplest terms, white point is the balance between the red, green, and blue primaries which, combined in equal amounts at full intensity, create white.)
Characterizing creates a monitor profile for use with a Color Management System (CMS). Once the profile is created, it provides information to ICC-aware applications about the monitor. An accurate monitor profile is critical to a color-managed workflow since you will be making judgments based on the colors you see on your monitor.
Third-Party Solutions
Monitor calibration and characterization is best done with specialized software and hardware. Most of the available products are for the Mac OS, though some are developed for Windows 95 as well. Adobe does not recommend any particular vendor's product, some tools range from relatively inexpensive software solutions, to more expensive hardware/software solutions.
Adobe Gamma
Apart from third-party tools, the Adobe Gamma control panel can provide reasonably accurate calibration and characterization that is sufficient for most color-managed workflows.
