ABSTRACT:
An apparatus for synchronizing movement of a camera with movement of an object to be photographed. The synchronizing apparatus includes a horizontal track which is disposed parallel to the path of movement of the object. A planar platform is movably mounted on the track and supports the camera. First and second pulleys are respectively aligned with the path of movement of the object and the track. An interconnecting cable is connected to the object and to the platform and passes around the first and second pulleys for causing an identical and simultaneous movement of the camera with movement of the object. In another embodiment, hydraulic cylinders and pistons are mounted on the dolly and the object and are connected in fluid flow communication for simultaneous movement in the same direction.
