For more than 100 years, movies have been a crucial part of pop culture, so that there is technology of movies that you have to know during that time. Even though movie is a photographic medium, it has related with computer, electronic, and electrical technologies. When silent films were emerged, projectors and cameras have applied electric motors in order to achieve constant speed of film. Electric lights are very crucial in terms of projecting and filming. In the beginning of studios, Cooper-Hewitt mercury-vapor tubes and arc floodlights were most important. In the 1920s era, incandescent tungsten bulbs were popular because the brighter incandescent lights were newly revealed at that time and because those bulbs did not generate the noticeable humming that can be found on the arc lights. The humming was very suitable for silent films. In the 1940s, tungsten floodlights which were supported with reflecting surfaces that were located inside the bulb behind the filament was very popular.
Transformation of Technology of Movies
The technology of movies had been transformed in the late 1920s. Bell Labs and Western Electric had collaborated with Vitaphone and Warner Brothers produced Don Juan. Don Juan was a sound movie which featured John Barrymore. This movie was launched on 6 August 1926. Even though there was no conversation, the music and a couple of saber clashes were connected to the actions. One year later, Jazz Singer that was played by Al Jolson came with spoken lines and this movie was box office that makes a lot of movie producers make sound movies.
As the time goes by, movie-making has been introduced with electronics. Sound can be converted by microphones to an electrical signal that would be amplified or meanwhile processed electronically. The photographic soundtrack was allowed by photocell to be converted back to electrical signal. Along with loudspeakers, the sound for audience has been recreated by amplifying tubes. Meanwhile, sound movies made the production of the photocells great because the first stage market was created for such tubes.
Electric lighting like neon and a couple of colored lighting and also sound systems and projection systems were crucial for the movies industry from the late 1920s to the 1930s. In the year of 1924, there was editing machine called Moviola. This machine had used variable-speed electric motor and pedal control. This was a very great innovation which made it easier in order to splice the footage together.
