You should join a photography or camera club, or become involved with the media department of your school. You may have the opportunity then to videotape sports events, concerts, and school plays. You can also learn about photography by working in a camera shop. A part-time job in a camera shop will give you a basic understanding of photographic equipment. Some school districts have television stations where students can learn the basics of camera operation. This kind of hands-on experience is invaluable when it comes time to find work in the field. You can also learn about the film industry by reading such publications as American Cinematographer (https://ascmag.com/magazine/) and Cinefex (https://www.cinefex.com).
Motion picture camera operators may work on feature films in Hollywood or on location elsewhere. Many work on educational films, documentaries, or television programs. The nature of the camera operator's work depends largely on the size of the production crew. If the film is a documentary or short news segment, the camera operator may be responsible for setting up the camera and lighting equipment as well as for supervising the actors during filming. Equipment that camera operators typically use include cranes, dollies, mounting heads, and different types of lenses and accessories. Often the camera operator is also responsible for maintenance and repair of all of this equipment.
With a larger crew, the camera operator is responsible only for the actual filming. The camera operator may even have a support team of assistants. The first assistant camera operator will typically focus on the cameras, making sure cameras are loaded and operating correctly and conferring with lighting specialists. In larger productions, there are also backup cameras and accessories for use if one should malfunction during filming. Second assistant camera operators help the first assistant set up scenes to be filmed and assist in the maintenance of the equipment.
Sometimes camera operators must use shoulder-held cameras. This often occurs during the filming of action scenes for television or motion pictures. Special effects camera operators photograph the optical effects segments for motion pictures and television. They create visual illusions that can add mood and tone to the motion picture. They usually add fades, dissolves, superimpositions, and other effects to their films at the request of the director of photography, also known as the director of cinematography or the cinematographer.
