06. an 07.01.00 Movies by hologram,
another application of the laser, has been
developed by Drs. Alexander D. Jacobsen,
Viktor Evtuhov, and James K. Neeland of
the Hughes Research Laboratories in Malibu,
California. They have been able to "produce
a 3-D movie." By this they mean "a movie
in which both subject and film move continuously throughout the filming and in which
the imagery is holographic rather than mere-

Iy stereoscopic." The latter uses two flat
images, each conveyed to a different eye
to give an illusion of three-dimensionality.
A holographic image is actually three-dimensional. Walking around it, the viewer sees
the same changing appearance as he would
walking around the object photographed; no
glasses are needed. The difficulty for application of this development for use by a
viewing public in an auditorium is first that
it is difficult for all of them to see the
image properly because it appears to be in
space before or behind the hologram. A
second difficulty would be to get laser beams
powerful enough to photograph outdoor
scenes in competition with sunlight. Finally,
the impediment necessary to create an
image in an auditorium with laser mirrors
and film in proper orientation would result
in u ncomfortabl e viewing by an audience.
The accompanying illustration (Figure 2)
showing the filming sequence for holographic movies is not lessened considerably
in the projection process. The subject being
photographed in the illustration consisted
of a tank of tropical fish, which produced a
moving image showing the fish swimming
around in space in front of the image. One
can well see where multi-media in the
theatre could be tending in the future. For
more information, see Science News, Vol.
95, May 10, 1969, pp. 460-461.
06.01 Hubbell now has available a twistlock to parallel blade adapter connector in
a single unit. The TLG male to parallel
blade plus ground female is catalogue
No. EK12305 and lists for $13.68 each.
These are a stock item with Hubbell and no
minimum order quantity is required. (Supplied by courtesy of Richard Thompson.)

06.01.03 Sylvania's third edition of their
Lighting Handbook is available from their
Danvers, Massachusetts, headquarters. Its
larger format is a distinct improvement over
the earlier editions of this very informative
booklet. (See Figure 3.)
12.01 For anyone involved in commercial
theatre ventures of any kind, information on
the dollar-and-cent rates for salary schedul es
is hard to come by and often Iimit an
assessment of cost that spells the difference
between profit and loss. Brooks' Standard
Rate Book, issued annually by Stanley J.
Brooks and Company (1487 Glendon Avenue, Los Angeles, California 90024) for
$8.00 contains this informationfortheWest
Coast television and theatrical film industry.
It includes IATSE, AFM, and independent
unions and guilds in its schedules. A look
at the table of contents indicates the wide
range of information supplied. It ranges
from all the production areas (actors, directors, extras, writers) to all technical production services (electricians, grips, sound technicians, makeup artists). It also covers a
variety of related service areas such as code
numbers (pension, health, andwelfarel, drivers, guards, pension data and codes, labor
for distant locations). It is unfortunate that
the East Coast and Midwest, where the complexity of the theatre-related institutions and
the overlapping jurisdiction is much more
"hairy," do not have a similar source book.
Perhaps Bernard Simon, who issues the
Simon's Directory (though not annually)
could be encouraged to enlarge the scope of
that very useful publication (Package Publicity Service, 1564 Broadway, New York
City 10036). (Courtesy of Richard Thompson.)
