Re: [photo-3d] Re: Vectographic motion pictures

My dream also.   Certainly possible, if (unfortunately) unlikely.  But then,
you never know.

Regarding the opposite film base sides, this presents more of a problem in
projection [projection lenses are often much "faster" (pass more
illumination)] than camera lenses, and have a VERY narrow depth of focus as
well as a narrow depth of field.

I heard of some work done by a Dr. Gold involving putting the Vectograph
images on the same side of the substrate, coating a very thin separator
layer in between.  Anyone have any info on this?

Normal color Vectographs have a minimum of six, usually eight (including the
"K" or black matrix) layers!  What a registration job!   Worth it though,
because nobody can misregister it once it is transferred.
