 Color Calibration for anaglyph 3D?

Is there a color calibration image, tool, wizard, app, or magic wand that will help me get the color from my monitor to best match the color of my lenses? I'm hoping this will help my brain stop the ghosting.

Got any other suggestions (that don't involve me buying 3 new monitors... I game in triple-wide :D)

You can only calibrate the colors to some degree. If you have ghosting from the beginning you should be able to calibrate it away a bit (by cost of colorreproduction). If the filters in the glasses aren't too god it doesn't matter what you do though. You can try with this image: The text should only be visible for corresponding eye. Besides: The more unaffected the brightness is for the unblocked image, the better.

There are quite a few sites that sells cheap anaglyphs. You should be able to find a few by a quick googling.
I even once made glasses myself but i'm out of filterfilm. The film i used was discofilters from Lee: (HT)026-Bright Red and (HT)116 Medium Blue-Green. These filters probably works just as good or even better than any glasses of the market.

Good luck!

Which anaglyph glasses are you using?

I've looked for one but couldn't find one so I made my own. It's a png since jpegs can have some color inaccuracy due to compression but I'm probably overreacting to that issue. You can probably use it as a jpeg and it should still be fine. Anyway, I tried to make it generic for all common anaglyph colors and here you go...

By the way, I've read somewhere that you need to match your glasses to the display and you can't really tweak the display to match the glasses. This seems to make sense since, in the case of a CRT, the phosphors emit certain wavelengths and so there's no yellow/cyan/magenta wavelengthed light coming from the screen. It's just an illusion, but wait, I guess there could be some yellow if the red or green phosphors had a wide enough frequency spectrum emission but not if it was a laser projector. I've heard there are/will be such things so in that case, there would be no yellow, just the illusion of yellow. In other words, if you put the "yellow" light through a prism, you would get red and green laser-frequency lines instead of a yellow line. Maybe such projectors would be good for anaglyph 3d. Couple a laser projector with very narrow-band filter-glasses and you should get ghost-free anaglyph. Hurray. Hurray for anaglyph 3d. ? Oops, got carried away. Anyway, I think this test image might be better used to compare various anaglyph glasses that you might have instead of using it for calibration.

bye.
