What cause Anaglyphic 3D ghosting?

How do you eliminate Anaglyphic 3D ghosting

Thank you in Advance

Besides a poorly calibrated monitor and a bad pair of glasses, too much saturation and contrast could be manually introduced during editing in one or more color channels. Using Auto Color could ruin it.

It might also depend on how the left and right images were captured. Were they captured at exactly the same time or not. If the images were taken with the same 2D camera where you moved the camera over slightly after taking the first shot in order to take the second shot, maybe the shots aren't perfectly aligned.

Those are my thoughts.

Thank You very much for your reply

Poorly calibrated monitor: Maybe here tried several adjustments.

bad pair of glasses: I'm using red/cyan gassess fro
www.3dgassessonline.com which are suppose be the best.

I thnk the problem is here in this area, saturation and contrast could be manually introduced during editing in one or more color channels. Using Auto Color could ruin it.

I use the Video FX Brightness and Contrast plug-in, If I remove it I still get the same amount of ghosting.

I need to try to adjust the saturation, next.

Would like like to know how to ajust the color channel per left or right images.

Thank You

I think part of the problem is that no filter is perfect. There will always be bleed, hence overlap and gosting, between the channels. Filters have no sharp cut-off. Even with polarising glasses, the 90 degree out of phase method, there is some bleed and hence ghosting.

Then again I may be wrong.

Another problem I ran into is when rendering an anaglyph to interlaced video, either upper field first or lower field first, such as DV-AVI. Now that produces ghosting.
