Is there a difference between a shadowless shed and a white shed?
The studio is a building dedicated to shooting. In the history of movies, the earliest studios were frames and glass ceilings made of metal and wood by sunlight. The working area in the studio is generally 500~5000 square meters.
It provides conditions for scenery, lighting, power distribution and hoisting, and is an important part of the studio. In the most primitive studio, wooden squares were only installed at the temporary positions needed for the lower chord of the roof truss to prepare for hanging light boards, fixing scenery and hoisting props. This is unsafe because the operator works at high altitude. After that, the overpass is gradually set in or under the roof truss.
Overbridges are divided into vertical, horizontal and vertical and horizontal types, and protective railings are provided for safety. However, there is still a gap between the overpass and the overpass, and it is still inconvenient to go to work.
Later, it developed into a grid-type (or grid-grid-type) ceiling, making the whole ceiling a workbench that can carry out all kinds of work everywhere, thus making the landscaping and lighting work more flexible, effective, fast and safe. Overpass and grille roofs can be made of wood, with light structure and low cost.
It can also bear the load. The most important thing is that it can fix the scenery on the wooden bracket very quickly and effectively with a simple method, but the fire resistance is poor.
It can also be made of steel or reinforced concrete, which is strong, fire-resistant and heavy-bearing, but it is too heavy to fix the scenery with nails, and it is laborious and inflexible to use metal connectors. The overpass is generally hoisted by an electric crane that can move along the track; Portable electric winch is used at the top of the grid, but it cannot move along the track.
