Creating nitrate film.

Emulsion is created by dissolving potassium bromide and gelatine in hot water, a clear glass container shows the chemicals mixing and being stirred with a glass implement. Intertitle: Coating machines spread the sensitive emulsion evenly on the transparent base that was made from cotton. The Film that comes from the machine is very similar to the film you buy in the yellow carton for your Kodak. A man in overalls works a coating machine, with a huge sheet of celluloid in. Intertitle: Absolute control of both temperature and mixture is necessary at this stage of film making to insure quality and uniformity. Temperature is controlling by means of several great refrigerating machines. Machines at work, frantic automated movements of the refrigeration machines, lots of spinning arms and levers.
