Television production and postproduction require an extensive array of equipment, but the most important element for television production is patience. Before any equipment has been turned on, before the lights have been focused, before the director has called his or her first shot, creative personnel must take the time to plan the production. Despite the best intentions of the production team, poor planning or a weak premise will only result in a feeble finished product.
Cameras and Accessories
Central to television is the use of cameras, which provide most of the visual elements that the audience sees. Basically, the camera is the visual acquisition tool that uses a lens to project an image (technically, the light reflected from the subject) onto the camera's pickup element, either an electron tube or a solid-state imager. The tube encodes the image into thousands of dots, and then an electron gun "reads" the dots and outputs the signal. Most cameras have replaced the tube system with a "chip" system (solid-state imager) that uses one or several charge-coupled devices (CCDs), which are smaller, more durable, and use less power than tubes.
Camera operators can control various elements of the image through lens selection and camera features.
