|Using Adobe Gamma
|Setting Adobe Gamma Manually
The alternative to using the Adobe Gamma Assistant or Wizard, is to make all your adjustments in the single Adobe Gamma control panel:
The settings you select in this control panel are identical to those you select the step-by-step method. They are simply presented in a single interface without instructions. In brief, the options are the following:
Setting the Monitor Profile
In the Description box, you will select the monitor profile you want to use as a starting point for the calibration:
For more information see Step 1 of Setting Adobe Gamma Step by Step.
Adjust Monitor Brightness and Contrast
Using your monitor's brightness and contrast controls, decrease the contrast between the black and gray sections in the upper bar as much as possible while maintaining the whiteness of the lower bar:
For more information see Step 2 of Setting Adobe Gamma Step by Step.
Confirm the Monitor's Phosphors
From the pop-up menu, select the phosphors used by your monitor:
For more information see Step 3 of Setting Adobe Gamma Step by Step.
Adjust the Monitor's Gamma
To adjust the monitor's midtones, use the slider to adjust the center gray box to match the outer pattern of horizontal black and white lines (it may help to squint when you do this):
The default option is to adjust gamma based on a single, combined grayscale reading. Gamma represents the point of equal amounts of red, green, and blue in the mid-tones; deselecting View Single Gamma Only allows you to adjust these separately:
Note, however, that we recommend using the single gamma for this adjustment.
You can also select the target gamma from the Desired pop-up menu. This setting will usually conform to hardware standards (1.8 for Mac OS, 2.2 for Windows). This option may not be available on some Windows computers because of the video card used. Additionally, it will not be available on Windows NT.
For more information see Step 4 of Setting Adobe Gamma Step by Step.
Choose Your Hardware and Adjusted White Point
Match the hardware white point to the white point you selected as suggested in the Before You Begin section earlier in this Techguide:
You can also set an adjusted white point if you have reason to work in a color space that is different from your monitor's.

Finish and Save
Finally, you can save the new Adobe Gamma settings. In Windows, click the OK button in the Adobe Gamma control panel:
In Mac OS, when you close the Gamma control panel you will be prompted with a Alert box asking you whether you want to save the changes:
Clicking Save (Mac OS) or OK (Windows) will open a Save As dialog box where you can name the profile and save it. Profiles must be saved to System Folder: ColorSync Profiles (Mac OS), or Windows\System\Color (Windows), or WINNT\System 32\Color (Windows NT). On Windows and Windows NT the file extension .icm must be used.

At the bottom of the Adobe Gamma control panel is a Wizard button (Windows) or Assistant button (Mac OS). Clicking these will take you out of the control panel to the Step By Step utility.
