While anaglyph PROJECTION is quite easy, making the slides is less so. I suppose
you could use a Q-DOS lens, as someone suggested, but I understand they are
fabulously expensive, and somewhat limited in how they can be used for maximum
effectiveness. Beyond that, you'd probably still have to shoot two images in any
of the normal ways, and then produce the slide from there. That could involve
manipulation in a custom lab (expensive and just try to find one) or scanning
into a computer, manipulating there, and the re-outputting to slide (time
consuming and hardware heavy). And after all this work, expense, and
fiddle-faddle, you'd wind up with an image that is roughly equivalent to an
Edison cylinder recording compared to a DAT tape! Ultimately anaglyph is 3D that
is useful when nothing better is available (like in print medium) but the worst
of all possible choices when anything else is available (as in projection).
