The
University of Southern California has one of the most respected schools of
cinema-television in the world. Many famous directors, cinematographers,
editors, and others involved in the production of motion pictures and
television programs learned their craft at this school.
Located below one of the buildings is the USC Moving Picture archive. The
archive includes over 18,000 student films, 35mm films, magnetic elements,
video tapes, posters, screenplays, cameras and projectors. It takes someone
with expert knowledge of the cinema to care for all of this – someone who
not only knows about the studios and people, but who also knows about the
technology behind the materials and equipment used to record and present the
images and sound that comprise cinema and television.
USC is lucky enough to have such a person. Herb Farmer is a Professor
Emeritus at the school and has been teaching there for over 30 years. But he
is also in charge of the archive, and looks after it with pride and the love
of cinema that permeates his being. He not only loves his work, but he is a
virtual fountain of knowledge.
The archive includes dozens and dozens of cameras, projectors, tripods,
blimps, and other items dating back to the earliest days of the cinema. The
equipment was acquired and donated by many people, including Mark Serrurier
(inventor and manufacturer of Moviola editing equipment), Sidney Solow,
(President of Consolidated Film Industries and for many years a regular
lecturer on laboratory and film processing), Sol Lesser (film producer),
Robert Nichols (heir to Art Reeves who was a founding ASC cameraman with a
sizable equipment collection), and Earl Sponable who was one of the chief
technical people at 20th Century-Fox from the 1920's until the 1960's.
Hundreds other individuals have also donated items to the archive.
With all of his hands-on experience with much of the equipment used for
filming and showing motion pictures, it isn't often that Herb Farmer comes
across items which are unknown to him. So when he offered to let a few
people take a look at some old large-format cameras and projectors and
equipment to help figure out what they were, it was obvious that the
equipment was truly unusual.
The lucky people that got to see this equipment in November of 2004 were Dan
Sherlock – systems engineer and
film format historian; Rick
Mitchell –
director, film editor and film format historian; John Hora, A.S.C. –
cinematographer and 70mm film advocate, and
Paul Rayton – projectionist at
American Cinematheque's Egyptian theater and also a 70mm film advocate.

During
the development of the large format processes around 1930, several different
formats were experimented with by various studios and individuals. William
Fox had purchased the rights to use a 57mm format called Widescope which
used a pivoted lens to record a wider-than-normal field of view. Fox and
others worked at improving the camera, with William Fox receiving some
patents on improvements to this camera. But at the same time, he asked his
chief technical assistant Earl Sponable to try to develop a simpler camera
and format that could achieve a wide screen and a wide field of view. This
second process became what is known as
Grandeur – a 70mm format with
larger-than-normal perforation holes and a longer-than-normal perforation
pitch of 0.234 inches. Because of the longer pitch, the frame on the film
was four perforation holes high even though the image was about 25% taller
than the silent aperture 35mm format. William Fox apparently decided to go
with the Grandeur format rather than the Widescope format and his studio
made a number of films in the process, including Fox Movietone Follies of
1929, Happy Days, The Big Trail, and a number of
newsreels. The MGM studio, which William Fox acquired the control of in
early 1930, adopted the use of the 70mm Grandeur cameras but elected to use
35mm reduction prints for exhibiting the wide screen image and referred to
the format as Realife. MGM also elected to use a larger area of the 35mm
film by cropping the image recorded by the Grandeur camera to a narrower
1.75:1 aspect ratio.
Fox had the Mitchell Camera Company create a 70mm version of their popular
35mm camera. This 70mm camera looked almost identical to the 35mm camera but
was just a little bit larger. Stein Camera Company in New York also made
some much larger cameras for Grandeur. This camera was later modified in the
1950's to become the first camera design used for
CinemaScope 55. Fox
supposedly also had the Wall Camera Company in New York make some Grandeur
cameras, but no photographs or examples of this camera have been found.
Kodak made the film using perforators loaned to them by William Fox.
International Projector Corporation made the initial prototype projectors as
well as the final "Super Simplex" projector design.
RKO teamed with George Spoor to utilize the 63.5mm Natural Vision format for
the feature film Danger Lights. The cameras and projectors were made
for Spoor in Chicago. But the Natural Vision format was developed during the
silent era, and the modifications needed to show the format with sound made
the process impractical for most theaters. So RKO also investigated the use
of other formats which might prove to be more practical.

Paramount developed a 56mm format called
Magnafilm which was basically the same image height and film pitch as
conventional 35mm film, but with the use of wider film to achieve a 2:1
aspect ratio. The format was used for an industry screening of a short
subject called You're In The Army Now in 1929. There were problems
evident at this showing, including a falloff in brightness at the corners of
the frame and some focus problems throughout the first reel of the
presentation. Those problems along with the difficulty in making a projector
that could handle both 56mm Magnafilm and conventional 35mm film caused
Paramount to abandon the process.
The most widely adopted large format process of 1930 was a 65mm format. The
format used the same sprocket hole and pitch as 35mm film, but with a frame
five perforation holes tall. Thus it achieved about the same size image as
Grandeur but with a conventional sprocket hole size and pitch. It is not
clear who originated the format, but several studios and equipment
manufacturers adopted the process. The Fearless Camera Company developed and
sold the Fearless Super-Film 65mm camera, which could also be adapted to use
35mm film. Warner Brothers called the format Vitascope, and developed their
own camera and two different projector designs. Warner Brothers used the
Vitascope format for a short subject called the Larry Ceballos Review
and the feature films Kismet, A Soldier's Plaything and The
Lash. Universal announced they would adopt the 65mm format and call it
Magnachrome, but nothing seems to have been exhibited by them using the
process. Paramount, having abandoned the 56mm Magnafilm format, had Andre
Debrie in France make a 65mm camera. Test footage was shot with the camera,
but it was never used for a publicly exhibited film. United Artists used the
65mm format and called it Magnifilm for wide film version of The Bat
Whispers. There is still a lot of debate as to which camera design was
used for this feature film. The Fearless Super-Film camera was available for
purchase and was an excellent design. Another report was that a 65mm camera
was made for Spoor in Chicago and wound up being used.
Mitchell Camera Company claimed to have modified a 70mm Grandeur camera to
use the 65mm standard for use on the movie, and research has confirmed
camera serial number 6521 was completed on July 1, 1930 and delivered to
Feature Productions. Feature Productions was the production company used by
Joseph M. Schenck who had produced the earlier feature film The Bat,
and he was also the producer of The Bat Whispers. And there is always
the possibility that multiple camera designs were used.
Besides the 65mm Warner Bros. projector designs which were used exclusively
in their theaters, Fearless developed a modification to existing Simplex
projectors for 65mm that could be installed for less than $300. The Ernamenn
company in Germany made some 65mm projector mechanisms for Paramount to use
in their 65mm experiments, even though very little information about the
equipment was published.

The Projectors at the Archive

The first thing we examined were two Ernemann
projector mechanisms which were made about 1930. We already knew that old
Ernamenn projectors from about 1930 were used during the development of
Todd-AO in 1953 to view the test sequences. What we examined, however, could
probably be better described as "projector mechanisms" since there were no
reel magazines, no pedestals, no lamphouses, no lens mounts, no shutters and
no motors. However, they bore a strong resemblance to the projector
mechanism shown in the February 1931 issue of the Journal of the S.M.P.E.
One of the projector mechanisms had sprockets designed for 65mm film. A
piece of modern 70mm film was fitted against the sprocket to confirm that
the size and spacing of the sprocket teeth were the same as the standard
used by Todd-AO and later 70mm formats. It also confirmed that there was
enough clearance to allow the 70mm width, which might be an indication that
there was some thought given to modifying the design if the 70mm format
based on Grandeur became a prevalent standard. It also confirmed that if
this was the projector design used by Todd-AO in 1953, then it would have
required very little modification from its original design to use the wider
70mm film used by Todd-AO as well as the 65mm format.

The second Ernemann projector mechanism was similar to the first except that
the sprockets were made to take either 65mm film or 35mm film. It had become
apparent to exhibitors in 1930 that if wide film was going to be adopted, it
would be necessary to have a projector that would work with both the wide
film format as well as 35mm film using either the full "silent" aperture or
the optical sound aperture configurations. Although neither of these
projector mechanisms were fitted for optical sound reproduction, the design
appeared to account for the optical track area. For example, one of the
rollers had a recessed area that corresponded with the sound track area.

The Large Format Camera Magazines

magazines. Image by Dan Sherlock
We next examined three different types of
large format camera magazines. The first was immediately recognizable as
magazines for the Fearless Super-Film camera that was introduced in 1930.
This camera was a very versatile camera that considerably reduced the amount
of noise made by the camera compared to other cameras of the time. The
camera was designed for the 65mm format that some of the studios were
adopting during 1930, but it could also be modified to work with smaller
gauges including conventional 35mm film.
The first thing checked with the Fearless magazine was if 70mm wide film
could fit through the film opening, which would imply that the camera could
possibly have been adapted to the 70mm Grandeur format if necessary.
However, examination of this opening confirmed that it was too narrow to
allow 70mm film to be used, and the magazine itself too narrow to permit
modification for the use of 70mm film. Thus, it appears that stories about
the Fearless camera being adaptable even for 70mm Grandeur appear to be
false, or else the stories actually meant that a new design based on the
concepts used in the 65mm camera could be made. The Super-Film magazine is
documented in U.S. Patent 2,007,468 published in 1935. This patent shows the
magazine being mounted to the camera via either a long screw located between
the reels, or using a threaded hole located towards one side which would
allow a thumbscrew to retain it to the camera. However, the actual magazines
use only the offset threaded hole and do not have the central long screw
shown in the patent.

magazines. Image by Dan Sherlock
The Fearless Super-Film camera and its 65mm magazines would be adapted to an
8-perf advance in the1930's and used for the experimental
Thomascolor
process, which used three areas (and later four) that were approximately the
size of conventional 35mm images to produce a three-color additive system.
The Thomascolor cameras would be returned to their original 5-perf advance
and have the camera apertures widened in late 1952 to become the first
Todd-AO cameras. These cameras were used for the first two Todd-AO feature
films and for a number of other productions, including some shots in
2001: A Space Odyssey and the short subject Probes in Space.
The inside of the Super-Film film magazine was covered in what appeared to
be black velvet. The rear surface was a disc spaced from the rear magazine
surface to provide a space suitable for 35mm wide film. Thus, when adapted
for 35mm film use, the film is offset towards the side of the magazine that
opens for loading and unloading of the film.
The second magazine type was slightly larger than the Fearless magazine and
was obviously designed for 70mm-wide film. The design of the magazine and
the mounting style were very similar to those used on 35mm Mitchell cameras.
The film chamber had a core 2 inches in diameter, and it appeared that it
would hold about 1000 feet of film. We later confirmed that this was indeed
a magazine for 70mm wide film and was designed for use on cameras made for
the Grandeur format.
The third magazine type was an unknown. It seemed to be designed to use 70mm
film, and the design and mounting resembled the 35mm designs used by Bell &
Howell on their cameras. However, there does not appear to have been any
mention in the press of a 70mm Bell & Howell camera being developed.

The Old Large Format Cameras

The first camera examined was truly a strange
beast. It was of open construction with no attempt and sound dampening. The
overall design, the viewfinder design, and the film magazine mounting
technique all seemed to indicate that it was made by Bell & Howell. Since
the odd film magazine also appeared to be of the style used by Bell &
Howell, we checked and confirmed that the odd magazines fit the strange
camera perfectly. No markings were visible on the camera, so there is
nothing to prove that it was made by Bell & Howell. But this does seem to be
the most likely scenario.
The camera had an aperture that measured 0.912 inches tall when measured
using a caliper. It was not possible to get the caliper into a position to
measure the width directly, but scaling the width from a photo of the
aperture reveals that it is about 1.89 inches wide. Although there have been
many contradictory specifications given for the Grandeur format, the most
reliable information (including measuring several published frame samples)
gives the camera aperture dimensions for Grandeur as 1.890 inches by 0.9125
inches. The fact that the camera aperture seems to match these dimensions
exactly and the fact that it is designed for 70mm wide film indicates that
it was designed for the Grandeur format.

P. STEIN & CO. nameplate on 70mm camera. Image by Paul Rayton
The second camera was one that some of us recognized immediately. It is
virtually identical to the camera shown in the photos of the original
CinemaScope 55 camera. The CinemaScope 55 camera was stated as having been
modified from a Mitchell camera originally made for the Grandeur format. One
of these cameras had been on display at the American Society of
Cinematographers (ASC) clubhouse for several years. However, the nameplate
on the camera we examined says "70 MM, [S/N] 9, WM. P. STEIN & CO., NY." and
there is no mention of Mitchell anywhere on the camera. (The camera that was
at the ASC clubhouse had an identical nameplate but it was marked No. 8.)
The design of the camera was very similar to a Mitchell, and the movement
was the same style as a Mitchell. And we confirmed that the Mitchell-style
70mm film magazine mounted perfectly onto this camera. But the camera is not
the same as the camera made by Mitchell for Grandeur movies. The Mitchell
camera was smaller than the Stein camera and looked almost exactly like a
conventional Mitchell camera except that it was slightly larger. The gauges
and indicators on the back of the camera were also positioned differently on
the Mitchell and Stein cameras.

70mm,
dual lens Nature Color, 8 perf Grandeur camera. Image by Dan Sherlock
However, this camera proved to be the biggest
surprise of our visit. For even though it was familiar in appearance, we
were surprised to see a dual-element lens mounted to the front of the
camera. The lens was marked "Bausch & Lomb 50mm Raytar f/2.3 No. 9". And the
case that the camera was kept in was marked "FOX NATURE COLOR FILM –
GRANDEUR". Nature Color was a two-color additive process that advanced the
film twice the number of perforations that were used for conventional film,
to expose an area about equal to two regular frames in size. Nature Color
was used by Fox back in the era around 1930, but there was never any
indication in what has been published that it was attempted with the
Grandeur format. (Apparently the format was originally called "Natural Color",
but the name was changed to "Nature Color" around 1930. It is quite possible
that the name change was to avoid having a similar name to the competing
"Natural Vision" picture format.) But the question remained if it was just a
Grandeur camera that had been modified for 35mm Nature Color use, or if it
could possibly have been an attempt to adapt the Grandeur format for 70mm
Nature Color use.

Upon looking through the viewfinder, we could tell that the image was
deigned to be a widescreen image of about a 2:1 aspect ratio like Grandeur.
When the camera was opened, the mechanism and sprockets confirmed that it
was for the 0.234 inch pitch 70mm Grandeur film and that it advanced the
film 8 perforations at a time, which is the equivalent of two regular
Grandeur frames. But the final confirmation was when we succeeded in racking
over the camera to expose the aperture. There were two apertures, one above
each other, with a strip separating the two. The apertures were measured
with a caliper and were 1.81 x 0.86 inches each. The strip between the two
apertures was 0.080 inches tall, so the total height of the double aperture
was 1.80 inches. Although these apertures were slightly smaller than the
standard Grandeur camera aperture, the aspect ratio is nearly identical. The
viewfinder was aligned so that it would look through the lower lens when the
camera was racked over.
The remaining two cameras were also immediately recognizable. They are
nearly identical to the camera shown and described on page 253 of the May
1956 issue of the S.M.P.T.E. Journal. They were painted white, had no
viewfinders, and were made by the Mitchell Camera Company and were
identified as model "FCD" which apparently stands for "Fox Camera Defense"
since they were made for the United States Department of Defense use. The
cameras were designed for the 0.234 inch pitch ASA Type I film used by
Grandeur. The Mitchell-style magazines that fit onto the Stein Grandeur
camera were also confirmed to fit onto these cameras. Since there was no
optical soundtrack used, the camera aperture was nearly the entire width
between perforations. The camera aperture was square, which gave an aperture
size of about 2.25 x 2.25 inches which agrees with the dimensions given in
the SMPTE Journal article.

The only known use of this format for public
exhibition of films for entertainment purposes was for the short subject
Journey to the Stars which was made for the 1962 World's Fair in
Seattle, Washington. The format was called Cinerama 360, and used a circular
area about 2.25 inches in diameter with a special 160 degree lens to
photograph a wide field-of-view scene for projection onto a large dome
screen above the audience. The camera and projector for this film was made
by camera division of the Benson-Lehner Corporation (which later became the
Cinerama Camera Corporation) and was based on the same specifications as
that used by the Mitchell FCD camera. Although the Defense Department
appeared to use the 0.234 inch pitch film for many purposes, the use of this
film for entertainment purposes and getting it developed by commercial labs
proved to be a nightmare. As a result, the second appearance of Cinerama 360
at the New York World's Fair in 1964 used conventional 70mm film, and the
ASA Type I 70mm film was never again used for entertainment films.
