I'm sure there's a good reason, but does anyone know why NASA shoots red/blue "3D" images instead of true stereo? I've always been disappointed in red/blue 3D; the stereo effect is minimal at best, and the diffraction "clutter" detracts from the detail, whereas in a true stereo shot detail does not suffer from these effects. Is anyone else "underwhelmed" by red/blue 3D? BTW, true stereo can be done with only one movable camera for landscapes. I shot true-color stereo images of Hale-Bopp, they turned out great. In that case, moving the camera was accomplished by waiting a few minutes between exposures- the earth moved it for me. C. __________________________________ Do you Yahoo!? Yahoo!
