do I leave the contrast at the max?




Yes. Changing it will obviate your AG profile.

Although it has been a few years since I read this, and I don't even recall the source, I have long followed the approach of always setting the contrast on a CRT monitor to maximum, and then using the brightness setting to adjust the display to my liking. This was said to result in running the CRT cooler and thus prolonging its life. Fact or fiction, true of older but not of newer CRTs, I don't know. But, it may still be credible advice and at least it seems consistent with the directions provided by Adobe Gamma.

I am attempting to use this program to configure settings for my new monitor. I have the values for phosphor(r,g,b).
White point is said to be 9300°K, per tech., although on another screen there is
"recall 6500°K". I called tech support of the manufacturer, and they don't have a number for gamma value.
Any suggestions will be appreciated.

Ken,

Probably you should go ahead and run the Adobe Gamma utility. You said you have the Hidden Power book, which has a lot of guidance for using the utility. Since you don't have a canned monitor profile, I think starting with the sRBG will do and you do have the phosphor values.

In most monitors the white point (color temperature) can be set by the user. Mine is set by using the "On Screen Display". Factory default seems to be 9300 degrees, a somewhat blue white compared to 6500 and 5500(or thereabouts) which are decidedly a more yellow white. Choose to suit. The pros, it seems from my reads, seem to favor the lower ones. I tried both and stuck with the 9300, but the setting is a personal decision I'd say.

It might be wise to make a copy of the sRGB profile (if you decide to go with that) and use for the starting point, just in case your renaming gets fouled up (lots of people have done this). Of course, another copy of sRGB is easily downloadable from the internet.

Gamma, 2.2?? for Windows

Kenneth,
Take a look at Ian Lyons tutorial on the Adobe Gamma utility. He'll recommend you set your monitor at 6500 degrees and 2.2 gamma ( but I don't do his tutorial justice ). <http://www.computer-darkroom.com/ps7-colour/ps7_2.htm> .

Another good resource is Norman Koren's site, <http://www.normankoren.com/color_management.html> .

Nancy and Brent,
Thanks for your posts.
When I bring up the on-screen monitor display, there are two color temp. screens:
1. Recall 6500°K Temp
2. Recall 9300°K Temp
I asked the tech about these and he told me that #1 has to do with yellow and #2 with blue-white. This agrees with the info. from Ian Lyons. I still don't understand, then, why the default monitor settings out of the box list both these K° values. Actually, the prints that I have made have pretty good color rendition compared to commercially produced prints. With the last roll I ordered a picture CD just to evaluate this. Of course, the CD just gives one JPG.
