A camera crane is a device used in filmmaking to move a camera vertically and horizontally with precision. It consists of a long arm mounted on a base, which can be adjusted to lift the camera high above the set or lower it close to the ground. The crane allows for smooth, sweeping camera movements and can capture overhead shots, dramatic angles, or tracking shots that would be difficult to achieve with a stationary camera. This equipment helps filmmakers create dynamic and visually engaging scenes by offering a range of movement options.
