Passion for engineering and passion for filming are not mutually exclusive and can both be integrated and used in your dream job. The two have been playing side by side ever since the beginning of the film industry. In fact, pioneer of the motion picture industry, Leon Gaumont, was a French engineer living in the 19th-20th centuries. He was always fascinated by photography and had pursued it in his career. He created synchronised functions of cinematograph and phonograph giving rise to sound film. Knowledge of light and sound effects is a crucial element of every production. Especially now, when special effects are getting more popular and sophisticated by day. And people behind these achievements are no others than engineers, amongst other members of the crew. Lets have a look at some examples of the engineering in film industry.
