Is the single bracket at a fixed angle?

A single camera has a fixed angle, that is, a machine is used to shoot a fixed lens, angle and orientation.

Single-shot shooting can usually be done independently by only one photographer, which is mostly used for photography and shooting with single lens requirements. Moreover, single-lens shooting has always been the mainstream production method, and it has been vigorously promoted and applied in the film and television industry since the 1950s.
