of the marine shots in the picture are made
with models. It would be prohibitively expensive to round up three full-size clipper
Ships just for a few moments of action. Besides, the miniature shots will be technically superior to anything that could be made
in full scale.
Water Dyed Blue
The studio "ocean" is a concrete tank 300
feet wide and 360 feet long. The water,
dyed an ocean blue, is three feet deep. One end of the
tank is half an inch lower than
the other sides and here the water continually overflows into a hidden trough,
giving a realistic horizon. From the trough
it is constantly pumped back into the tank.
Behind the trough is a 50-foot tall background screen painted in imitation of a
blue sky flecked with white clouds. The
smog-brown Los Angeles sky won't be
visible to the camera. Wave machines and
wind machines are lined up along one side
of the tank.
