Step 7

Choosing the "White Point" for your monitor is pretty much a formality these days. Even the die-hards are in agreement that 6500oK is probably the best option on most systems.

You should have already set the Hardware white point via the dials/buttons on the monitor. Most monitors have a native white of 9300oK, so do make sure and check what it has been set to.

Choosing 6500oK provides the cleanest and brightest white point and closely matches daylight. If you feel really confident you could select the "Measure" option, but be prepared for a struggle. You can choose 5000oK, but this usually produces a slightly dimmer and more yellow white point.

Step 8

Generally speaking, it's better to leave the Adjusted White Point setting at "Same as Hardware". 

Nevertheless, this option, when available, is used to choose a working white point for monitor display if that differs from the hardware white point set in the last step. For example, if your hardware white point is 6500oK, but you want to edit an image at 5000oK  because that most closely represents the environment in which it will normally be viewed, you can set your Adjusted White Point to 5000o K, and Adobe Gamma will change the monitor display accordingly: However, choosing this approach will all cause the graphics card colour LUT to be adjusted quite severely, and depending upon the graphics card the screen can look quite ugly on some systems. As indicated above I recommend that you choose "Same as Hardware" and thus avoid this problem.

Step 9

That's it, if all has gone well you will have adjusted the brightness, contrast and colour settings of your monitor to the optimum values.

Make a quick check using the "Before" and "After" radio button. If you're happy that the screen display now looks more neutral than before press the "Finish" button and "Save" the profile. Once saved the profile will be available for use by the OS and Photoshop.

The advantage of Adobe Gamma is that it's free, whereas the third party products can cost nearly as much as Photoshop. However, since they use "hardware" and not the "eyeball" for the measurements we are assured of much more accurate calibration.

There are a number of third party alternatives to Adobe Gamma, which can be purchased from companies such as Color Vision and Xrite.
