Выбор штатива для видео камеры
Существует широкий спектр аппаратуры для камеры, предназначенной для выполнения разных требований съемок программ несколькими камерами в студии и на натуре. Ни одна аппаратура не охватывает все виды съемки и все оборудования.
Choosing a camera mounting
There are a wide range of camera mountings available to cover the diverse requirements of multicamera programme-making in the studio and on location. No one camera mounting will necessarily embrace all styles of camerawork and all weights of equipment.
The first selection criterion is to know if the mounting is to be transported to its operating position (i.e. at a location rather than operated daily in a studio). Equipment that may have to be carried up stairs or rigged in difficult locations will need to be lighter and more easily rigged and de-rigged compared with equipment used permanently in a studio.
The second requirement to be considered is if the mounting is to be used to reposition the camera ‘on- shot’ or if it is simply to have the ability to reposition ‘off-shot’. A tripod on wheels (if the ground surface is suitable) can be repositioned to a new camera position, but is unsuitable for development shots. A pedestal mounting with steerable wheels and smooth adjustment of height will allow a development on shot if operated on a level floor.
The third consideration is the all-up weight of camera, lens and, possibly, camera operator the mounting will need to support. The simplest way of moving a lightweight camera is to carry it on the shoulder (on or off-shot) although this will not give such a smooth movement as using a harness around the torso to steady the camera. There are a range of lightweight tripods, portable pedestals and jib-arms that can be used with a lightweight camera. There is also the facility to rig a lightweight camera on the end of a boom arm and to remotely control its movement on a servo-driven pan/tilt head and to remotely control the lens. At the other end of the scale there are cranes capable of elevating a full facility camera and camera operator to a lens height of over twenty feet.
