Quote: I've seen big rocket launches filmed in 3-D IMAX. Very impressive,
but, well, I wish they had used a vertical, not horizontal, format.
There used to be a circus exhibit at Chicago's Museum of Science & Industry
that included a film that was shot in 65mm/5 turned on its side. It was
projected via 16mm triple frame. Projector was an ordinary 35mm machine, a
Century as I recall, with custom 16mm sprockets, gate and trap with film
handled in one of those endless loop things atop the projector. Sound was
35mm full coat looped up and down on a slew of rollers.
I suggested to my friend, who was servicing it for a time, that the
projector be converted to run normal 35mm and the museum ought to get
prints made as anamorphic reductions with vertical lens orientation. The
frames would be masked in on either side as that seemed better than either
rotating the image or the machine. But that went nowhere as with lab
changes no one could find the 65mm O-neg; all they had was the 16mm optical
dupe. I think it would have been a vastly better and brighter picture and
eliminate expensive custom projector parts. Film handling would have been
a duplication of the rollers used for sound.
At the time MSI was also running an agricultural film using the 16 triple
frame format but projected via Pechan prism to give a widescreen image. I
don't know anything about how that material was shot. |

Hulcher made a bunch of high speed cameras that NASA bought among others,
and they used Type I film, since it's has a lot less wasted area. Hulcher
also made some high speed 35mm cameras in various formats too, mostly for
government use.
The aerial photography guys still go through a lot of Type I film, and you
can get backs for a lot of still cameras to use the stuff.

I've seen big rocket launches filmed in 3-D IMAX. Very impressive, but,
well, I wish they had used a vertical, not horizontal, format.
Likewise, Swinging Stewardesses would have benefitted from a horizontal
rather than a vertical format.
I think it's important to be able to pick the aspect ratio for the subject
in question. I miss composing for Academy aperture too.

This is probably what's referred to as Military 70mm, which uses a ten
perf frame.
