Westinghouse executives commissioned Biograph to produce these films, intending to exhibit them to their subsidiaries and employees, thus making them some of the earliest existing examples of what are now called industrial films. They cannot be called documentaries because they were paid for and made according to guidelines set by the manufacturing company. In addition, they cannot be called commercials because they do not advertise individual products and were not exhibited widely to elicit sales.
The films were the first to use mercury vapor lamps (conveniently made by Westinghouse) to illuminate its shots, and they were also the first to use crane shots. Bitzer primarily used stationary cameras and fixed lenses, and he typically shot the films in a single continuous take.
Most films did not have title cards, so many of their names were assigned by the Library of Congress.[2]
Release
The finished films were shown to Westinghouse employees in Pittsburgh, narrated by a speaker. They were later exhibited at the Louisiana Purchase Exposition in St. Louis (accompanied by organ music), and were received positively by audiences.[2]
