This will be a longish reply <_<
Whitepoint settings on CRT monitors usually ranges between 5000K and 9300K.
6500K is described as "daylight" and is considered the "neutral illiminant". Less than 6500K will look yellowish, more than 6500 will appear blueish.
(As background, the temperatures refers to the color of an iron bar when heated to a certain temperature and the color it will emit at that temperature)
According to the ISO norm (3664:2000), use 6500K as whitepoint for the monitor.
Gamma is used to describe the transition of brightness from black to white for a device in this case a monitor.
Gamma values range from 1.0 to 3.0 but in practice tend to be between 1.8 and 2.2. The lower the device gamma, the brighter the mid-tones will appear.
Gamma for windows environments is recommended to be set to 2.2, for Mac they usually say 1.8.
Now here comes the catch:
If you are really serious, you should probably have a chat with the wife/girlfriend as well:
If you want optimal viewing, you'd have to paint the room in a nice neutral shade of gray or mossy green and use 5000K (d50) TL lighting. Then you'd have to make certain that outside light doesn't influence viewing conditions inside, so preferrably you'd have to blind the windows.
My whole point is actually that you can take it as far as you want to take it, your pics will look great on your monitor, but when other Wetpixel users download them onto their monitor, they might look completely different...
The Eye one is a good tool, I'd say better then the Spyder.
Do you have the Eye One with printer proofing or without printer proofing?
I have the version that has printer profiling as well, which is a nice feature since it makes me independant from the ICC profiles provided by the manufacturers.
