The Adobe Gamma control panel should be located in the Program files/Common
files/Adobe/Calibration folder which can be easily accessed on a PC by going to My
Computer and selecting Control Panels.
Adobe Gamma will now work with most PC
computers, providing the video card will allow Adobe Gamma to interact with the
monitor tube. Do not use the older Gamma control panel which shipped with
Photoshop 4.0 or earlier. This older control panel must be discarded.
When you launch Adobe Gamma, you have a choice of using it in either Control
Panel or Step By Step (Assistant) mode. Select the Assistant radio button and click
Next. If you already have a monitor profile, such as a canned profile supplied by the
manufacturer, click the Load… button, locate this profile and use that as your starting
point. Any existing monitor profiles should be found in the ICM Color Profiles folder.
If not, any will do as a starting point here. You will be asked to set the monitor
contrast to maximum. The single gamma display box will only allow you to adjust
the relative brightness. But since you will want to neutralize the color as well, uncheck
the View Single Gamma Only box and adjust the three color boxes as outlined in the
Mac OS X calibration routine.
The Windows default gamma is 2.2 and this is the best monitor gamma setting for
most Windows graphics cards. The white point should be 6500 K, if unsure, try
clicking on the Measure… button and following the on-screen directions. The next
screen asks if you want to work with a different white point other than that entered in
the previous screen. Unless you have a particular need to alter the white point, leave
this set to Same as Hardware.
If you are using a thirdparty method of profiling the monitor on the Macintosh, other than a system
utility, you may be required to manually load this profile next to where it says Display Profile in the ColorSync Control Panel (OS 9), or in the ColorSync System preference (Mac OS X). On a PC, you will probably need to carefully consult the instructions which came with the calibration device. These should guide you through the intricacies of how to configure the Windows system setups.
