Did you elaborate on the shooting techniques and skills of 3D movies?

The shooting of 3D stereoscopic images is more complicated than ordinary movies, and there are specific requirements, not only for the target scene (suitable for representing 3D stereoscopic images), but also for the shooting equipment. That is, professional equipment for shooting 3D stereoscopic images needs synchronous exposure, synchronous focusing and frame synchronization if it is shot with two cameras (or two lenses of a single camera, each with its own advantages and disadvantages). In addition, if it is shot at close range, it must be able to adjust the close distance between the two cameras (. Obviously, if any video camera is juxtaposed, its lens distance will far exceed 70 mm, so the two machines need special combination installation, which gives birth to the equipment of vertical reflection 3D bracket. However, this kind of equipment also has many shortcomings, which hinders the development of stereoscopic imaging to some extent.
