ABSTRACT:
A leveling head for a camera has four jacking screws attached to a base plate. A ring is pivotably attached to a hub on the base plate. A top plate is pivotably attached to the ring and supported on the jacking screws. The top plate can pivot along two perpendicular axes relative to the base plate, to provide a level mounting surface for a camera. A spring on the base plate pushes the top plate upwardly, to partially counterbalance the weight of the camera, to reduce the turning force needed on the jacking screws.
