Hi, John,
Thank you so much for filling in so much more information--at a higher
level--than I was ever involved in.
I agree, a good slide-tape-film show can be truly inspiring and
immersive. I had forgotten the joys (??) of pin-registration.
How did pin-registered mounts register in Carousel projectors?
I remember Chief stands and there was another optical company (other
than Buhl) who was servicing this industry. I think Buhl was out of
Pittsburgh and the other company was out of Rochester.
I _think_ The New York Experience was using a 1/2-inch 4-track tape
machine--an audio format that was considered more "professional" than
the 1/4-inch 4-track that you mentioned. And yes, their "machine sitter"
in the booth was there because of the well-known cantankerous nature of
these shows. They were certainly not a kiosk computer playing back a
PowerPoint.
The point I think I was originally trying to make was that properly
archiving one of these shows is very difficult to retain full impact. I
doubt that many (if any) of these will ever be seen again in their full
glory. If we wanted to classify these as "formats", we would probably
need to classify each configuration with each manufacturer's control
protocol as a separate "format". You did mention the two-wide with
centre overlay as a common format. I do recall seeing a number of these
at National Park venues. I was thinking about the more elaborate ones
that added another panel and another splice (at least) for five stacks
of projectors.
While this is beyond my personal experience, I think I recall three
projectors being common in a stack: A, B, and "Flash" where A and B
dissolved into each other and the "Flash" projector would show an
overlay independent of A and B.
I _think_ I've also seen film shown in a window created by a slide (i.e.
there was a totally black area in the slide and that's where the film
hit the screen). You couldn't really use 16 mm film at the same size as
a 35 mm slide as the film's much lower resolution would be immediately
obvious.
Ahh, the complexities we used to go to...
Cheers,
Richard
