What is the function of 'pedestal' in camera operation?

The function of a 'pedestal' in camera operation is to raise or lower the camera while keeping it stationary. This allows for precise adjustments to the camera's height without changing its horizontal or vertical orientation. A pedestal is often used during filming to achieve different shot compositions or to follow the action of the scene smoothly, maintaining the desired framing while ensuring stability.

The other options focus on movements or actions that do not accurately describe a pedestal's role. For instance, movements left and right would typically involve a different set of equipment or techniques such as a dolly or tripod with panning capabilities. Manipulating the camera angle horizontally is more aligned with panning, which again does not pertain to the pedestal's function. Stabilizing the camera during panning usually involves tripods or stabilizing devices rather than the pedestal itself. Hence, raising or lowering the camera while stationary is indeed the distinct and accurate function of a pedestal in camera operation.
