Technology It is common for professional cameras to split the incoming light into the three primary colors that humans are able to see, feeding each color into a separate pickup tube (in older cameras) or charge-coupled device (CCD). Some high-end consumer cameras also do this, producing a higher-quality image than is normally possible with just a single video pickup. Studio cameras Most studio cameras stand on the floor, usually with pneumatic or hydraulic mechanisms to adjust the height, and are usually on wheels. Any video camera when used along with other video cameras in a studio setup is controlled by a device known as CCU (camera control unit), to which they are connected via a Triax or Multicore cable. The camera control unit along with other equipments is installed in the production control room often known as Gallery of the television studio. When used outside a studio, they are often on tracks. Initial models used analog technology, but digital models are becoming more common. Some studio cameras are light and small enough to be taken off the pedestal and used on a cameraman's shoulder, but they still have no recorder of their own and are cable-bound. ENG cameras Often used in independent films, ENG video cameras are similar to consumer camcorders, and indeed the dividing line between them is somewhat blurry, but a few differences are generally notable: Dock cameras Some manufacturers build camera heads, which only contain the optical array, the CCD sensors and the video coder, and can be used with a studio adaptor for connection to a CCU or various dock recorders for direct recording in the preferred format, making them very versatile. However, this versatility leads to greater size and weight, and dock cameras have become rare in recent years. They are, however, still favored for electronic field production and low-budget studio use, because they tend to be smaller, lighter, and less expensive than most studio cameras. | ||||||||||
