That's basically what's been done now, Gord. I haven't done a setup before and from everyone's memories the projector didn't need to be tilted... poor memories it seems? The problem is that this is a 3D festival, with over/under, side-by-side, and anaglyph movies all mixed up. Luckily I don't have to actually run them and manage the changes of tilt and lenses... The Motiograph pedestals do in fact have handwheels, under one of their many access doors, so tilting is at least a one person job (whew!). Even with the framing centred and the scope aperture plate (pretty close to full width and no cutoff visible on either image) the thing throws ghost images.. you get the left eye on the ceiling and the right eye on the floor, I think. With some more time and experimentation I think some sort of cardboard mask with two holes, placed close enough to the stereoplex box that the 3D images haven't converged together, would block these ghosts. Thanks for all the suggestions. I may try and talk to Mr. Condon on Monday and see what he recalls. Does anyone know if there's still anywhere that can replace the polarizers, or if this is something that I could do? And does anyone have a pair of Sterovision stereoplex units for sale? The Paramount ones I've seen on ebay are too bloody huge: the theatre is asking about buying a pair, and our only rental set is still occasionally used by a few silver screen houses so we don't really want to sell them.
