Theatre Design & Technology - May 1971 - 19

I am currently embroiled in a production
of Macbeth. The director is not technically
sophisticated but we have lots of technical
people to back him up.
He was worrying about the dagger, "The
dagger I see before---" etc. Ming, darn
him, suggested that perhaps this ought to
be a hologram.
Now, a hologram is a tremendous thing.
If any of you have not seen a hologram, I
commend to you the hologram demonstration on the second floor mezzanine of the
G.M. building. You can walk around an old
Fisher coach and an auto body. The lights
come on and, poof, it's gone.
This hologram is very carefully enclosed,
very carefully isolated from all lights, and
rather dangerous if you have to get anywhere near it.
Nothing would do but that we come back
with some figures. The expense was staggering, to say the least, and the ancillary
conditions-getting out light and keeping
people away, etc., ruled it out abruptly.
I don't think it has arrived for us yet.
MR. OENSLAGER: If you project a set in
the center of a theatre in the round with a
laser beam, how I don't know, does it mean
you couldn't have any other light in the acting area?
MR. WARFEL: Right now it does. and they
are never big enough now to approach the
proportion of a piece of scenery.
MR. OENSLAGER: Suppose it could be
projected up in scale. Can you still use acting area lights in conjunction with it?
MR. WARFEL: With the present technology
you cannot. It must be used in absolute
darkness.

MR. GERSZTOFF: I came across an article
recently noting a technique that has been
developed and licensed by a particular company to produce motion pictures with holography so that you would have, in essence,
a three-dimensional motion picture image. It
has also been carried to the point where a
full-color image is possible rather than the
standard all red or all green. So progress is
being made.
MR. OLSON: We have dealt with a number
of points here in and out of order, but I
think Point Eight is next: a spotlight with
accurate, simple control and focusing apparatus.
MR. GERSZTOFF: I think we still have a
long way to go on that.
MR. OLSON: Why? '
MR. GERSZTOFF: They don't stay in focus.
Framing shutters on an ellipsoidal, after two
scenes, come out looking like pieces of
corrugated paper. They are expendabl e
items, and they don't need to be.
If you tighten up a unit so it stays in
focus, you can't undo it again.
The technology exists to make a good ellipsoidal spotlight.
