on the dolly with the camera. Lightweight dolly systems are more simple and affordable, and are best used with lighter-weight cameras. Lightweight systems are usually favored by independent filmmakers and students because they are easier to carry and operate. These dollies support only the camera, and the operator needs to move alongside. Some lightweight dollies are small enough to be carried in a backpack. The best way to be able to replicate the same camera movement for multiple takes (which is important for editing) is to use a dolly on track. Remote dolly systems In TV production, remote controlled camera dollies are often used for fast but discreet camera movement. A metal rail is laid out for example in front of a stage and a remote controlled dolly is moving the broadcast camera horizontally, where a cameraman would obstruct the view for the audience behind the camera. A common remote dolly system with camera stabilization is a Blackcam dolly with a Newton stabilized camera head. Track Dolly tracks used for heavy cameras have traditionally been constructed of steel or aluminium. Steel, although heavier than aluminum, is less expensive and withstands heavier use. Longer track segments, while heavier to transport, allow track to be laid straighter with less effort. Curved track is also available. Plastic versions of track have been used with lightweight dolly systems. In the 2000s, flexible rubber track allowed quicker set up and easier transportation for use with light cameras.
