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