Color Correction and Stereo 3D Compensating for shutter dimming
The default appearance of 3D with my shutter glasses out of the box is way too dark, and the color is severely desaturated. I have created a custom color setting (as I'm sure many of you have) that I would like to share.
The object is to reproduce the original color as much as possible with the shutter glasses on. As you know, not only are we looking through the darkened filter of the shutter glass, but we are also absorbing half the light each frame (one eye). In addition, the eye's response to color changes greatly depending on the light.
Stereo Gamma Setting in the Nvidia Control Panel is set to 1.30
Color Correction (Advanced) curve:
In: .0 Out: .0
.58 .80
.69 .92
.80 .97
1 1
Digital Vibrance: 1.2 (Medium)

OK, so if you've never thought of adjusting your color, try this out and see if you like it. And of course if you've found something better, please share it!

Dude, I've suggested colour adjusting via digital vibrance a long time ago in the stereovision forum - [url="http://forums.stereovision.net/viewtopic.php?topic=2134&forum=5"]http://forums.stereovision.net/viewtopic.p...ic=2134&forum=5[/url]
however I think that setting the digital vibrance to medium is too much, I personally keep it on the border between low and medium.
As for the colour correction curve I've never tried it, it should be interesting though because using digital vibrance makes the colours a little artificial in certain games. It is a great improvement nevertheless over the washed out colours resulting from stereo.

Digital Vibrance is certainly an essential part, but the biggest difference is in the color correction. In my line of work I've had to try to understand the mathematical compensation for gamma response when going from:
[i]real world -> film -> projection -> your eyeball[/i]
Each '->' is a different response curve (even your eye has "gamma"), so when you add another layer (i.e. shutter glasses) it changes everything. Anyway I'm no scientist and it's a real b**** so in the end I just ended up fixing this with trial and error.
An ideal (but impossible) solution is to make the monitor's brightest values even brighter. In fact, a monitor's brightness control doesn't do this, it actually just brings up the black level, kind of like gamma. The alternative I chose is to "crush" the brightest levels. When using my settings, you will notice that the brights/highlights will be "blown out": that is, not a lot of detail. This will work fine for games, though, since we don't really care about the bright areas anyway (e.g. you don't need to see every sunspot when staring at the sun). However, a medium DV of 1.2 will make sure that your colors still remain vivid.
In total, this allows us to maximize the brightness and contrast in the mid- and low-value areas, which is where we all the interesting stuff happens. Hopefully if you try my correction curve you will find that when you put the shutter glasses on, you will see an image that looks a lot like what your games were originally supposed to look like.

I did that and it was a very pleasent surprise! Thx.
I spent a couple of hours adjusting and settled on:
stereo gamma setting 1.00
Digital Vibrance Low (in center of Low range)
0.00 0.05
0.38 0.47
0.70 0.86
0.84 0.95
1.00 1.00
Monitor temp 5000K
Monitor brightness standard + Ultrabrite
This is good but can probably be improoved. I used to just increase the brightness and lower the color from 6500K to 5000K on the monitor. But this is better.
Edit: why isn't these things in a sticky or a manual really? This is essential stuff. Maybe someone can measure the effect the glasses has on a colorcurve in 5min.

I found this nice. Im sure itll take some tweaking for each game, and personal preference but I went with the original posts settings and did see a nice difference, so its worth while to toy with and make profiles for games.
Would be neat if nvidia could assosiate these color profiles with the stereo profiles as well. =)

The coordinates (numbers in question) is the "In" and "Out" numbers of the points on the graph. You can create new movable points on the graph by clicking on it.
Experiment until You find a setting that compensates for the darkening/colorremoving effect Your glasses applie to the game.
That's how I do it anyways.

since Nvidia has scrapped support for shutterglasses (I have core2duo and 8800gts), I figured to give it a try for anaglyph glasses and the new Vista stereo driver.
however i do get the picture in greenish hue, and overall the picture looks desaturated - digital vibrance helped it only a bit.
have anybody figured this out (color correction) for Vista Nvidia control panel.
more or less it works -> "Adjust desktop color settings".
but it seems that color controls are "dumbed down" since the old driver control panel. I couldnt adjust values for seperate color channels and remove greenish hue. (I could select the channels, but it seemed that the sliders did affect all channels anyway.)
