There were several 3-D films at SIGGRAPH this year which used polarization
to achieve left eye/right eye distinction.

My question is, what are the actual mechanics of placing the two images on
film? Is the film double exposed, once for each image of the stereo pair,
with different polarization each exposure? Does the film grain retain this
polarization? Or is it a special type of film with a polarized emultion on
each side?
