Underwater Seminar
by Rusty Geller
Making movies underwater has always been
difficult. In the last fifty years, with the invention of scuba,
portable cameras, innovative waterproof housings and versatile
underwater lights, underwater cinematography is now approaching
the flexibility routinely achieved above water.
The first divers were merely hunting for
food. Working professionally underwater started with the ancient
sea-faring civilizations, which used slave labor to salvage
their sunken treasure ships. Needless to say divers didn't
get hazard bumps, meal penalties were unheard of and the only
retirement program was not making it back to the surface. The
first underwater tourist was Alexander the Great, who in 332
BC had himself lowered to the bottom of the harbor of Tyre
in a glass barrel so he could watch his diving soldiers destroy
the Phoenician's underwater defenses.
Compressed air was first used to supply a
diver in the eighteenth century, but the hard-hat system was
heavy and cumbersome, and the diver was tethered to the surface
by his air-supply hose. Nevertheless, as early as 1906 a Japanese
diver shot still photographs underwater off California's Channel
Islands. In the 1940s Jacques-Yves Cousteau and Émile
Gagnon invented the self-contained underwater breathing apparatus
known as scuba and man was freed to explore the seas like a
fish.
The first underwater movie camera housings
weren't much more than steel pots with portholes welded into
the lids. As cinematography became more sophisticated, so did
the requirements of underwater cameras. Today's underwater
housings are well-thought-out, user-friendly pieces of equipment
which allow the cinematographer full use of the modern motion
picture camera underwater.
Until recently, underwater camera systems
were usually one-offs, built for the particular requirements
of a specific project. Ten years ago Pete Romano standardized
his design of an underwater housing for the 35mm Arriflex III
camera while shooting underwater sequences on The Abyss for
James Cameron. With a dozen of his new housings, Pete opened
HydroFlex Inc, which manufactures and rents underwater systems
for 16mm and 35mm Arris, IMAX and video cameras, as well as
camera splashbags, light meters, and complete underwater lighting
packages.
This past summer, on July 24, 2000, the SOC
along with HydroFlex and PhotoSonics co-sponsored the second
annual Underwater Cinematography Seminar, held in a private
community pool provided by SOC past president Stan McClain.
Fifteen DPs, operators and assistants spent the morning going
through a detailed training session on each camera housing,
followed by an afternoon in the pool operating the cameras
underwater.
Scott Greene of HydroFlex presented their
three main 35mm Arri III housings: Surf, Shallow Water and
Deep Water, along with their new torpedo-shaped Remote Aqua
Cam housing for the Arri III, which was designed for remote-crane
use primarily with the Libra III axis head, or to be hard-mounted
on underwater vehicles. There is now an Arri 435 version available.
Tom Boyd of PhotoSonics presented their 16mm
and 35mm high-speed cameras (10-200 frames per second) in lightweight
hand-holdable reflexed video-tapped housings designed for surf
and shallow water work down to 20 feet in depth.
Wayne Baker, veteran underwater assistant
and operator, took the students through a typical shoot, from
prep to filming, emphasizing the flexibility and resourcefulness
required to deliver good footage in adverse conditions. He
shared such tricks as using Rain-X on flat glass ports and
Photo-flo or dish soap on flat acrylic ports, to shed water
drops while doing surface shots. He went over the differences
between dome and flat ports, and how to follow focus while
underwater where refraction makes everything look a third
closer and a third larger. Wayne explained the necessity for
using an opaque-skirted face mask to avoid reflections in the
finder, using rubber-coated weights to avoid damaging the bottom
of pools, and how to re-route the underwater cameraman's bubbles
when shooting straight up. He also went over precautions when
filming explosions underwater: namely, get everybody out of
the water, including the camera operator before setting off
the charges.
Matt Brown and Scott Greene of HydroFlex
went through their underwater lighting packages, including
650 Watt, 1-K, 2-K and 5-K tungsten lamps, 1200, 2500, 4-K
HMIs, and Hydro-Flow Underwater fluorescent lamps which come
in 2900, 3400 and 5500 degree color temperatures and in 9",
15", 2' and 4' sizes.
Safe and proper use of electricity in pool/boat
situations was emphasized. The HydroFlex lighting systems have
redundant Ground Fault Interrupters, but the weak point of
poolside shoots is unprotected video power which can shock
the camera operator by sending electricity back down to the
camera through the video assist cable. Video assist operators
should always power the decks and monitors by batteries, or
through a GFI, which can be supplied by HydroFlex. Gaffers
should run all their waterside power through Shock-Blocks.
Once the serious note-taking was through,
it was time to hit the water. The pool soon filled with divers,
tanks and cameras. Shallow Water and Deep Water housings crisscrossed
the bottom of the pool as those participants who were certified
divers got the feel of operating underwater. The Remote Aquacam
made its free-swimming debut with a waterproof video monitor
as a viewfinder. Veteran underwater cinematographer Mike Thomas
demonstrated his watertop dolly, floating the Deep Water Housing
across the surface of the pool as easily as a Fisher Ten on
a dance floor. Each camera had a video umbilical to the deck
and students could watch the high-tech underwater rodeo on
surface monitors.
As the students took turns on each camera,
they saw the plusses and minuses of working underwater. The
housings weigh up to eighty pounds out of the water, but once
below float almost weightless. At first, one is surprised at
the ease of moving the big cameras, but soon it became apparent
that the housings have a lot of mass and limited hydro-dynamics,
and if you tried to move them quickly, you moved instead.
As the participants adapted to working in the weightless environment,
they came to realize why experienced underwater operators wear
double-weight belts and ankle weights.
Assistants learned that it's not easy to
see the lens markings while underwater and extra care must
be taken when setting up the controls before sealing the housings.
Operators discovered that the reflexed optical finders seemed
dim in the bright pool, which is why HydroFlex offers video
sportsfinders as an accessory.
Despite the use of underwater loudspeakers,
communication is difficult and it quickly became apparent that
extensive pre-planning of all shots is essential. Two-way communication
systems are recommended if the job is elaborate or lengthy.
As the divers dried off and packed the gear
at the end of the day, they all seemed invigorated, excited
at the prospect of expanding their filmmaking challenges to
the underwater world. HydroFlex, PhotoSonics and the SOC put
a lot of effort into the seminar and it paid off. Fifteen talented
cinematographers are now up to speed on shooting underwater
with state-of-the-art equipment.
