Crane shot

In filmmaking and video production, a crane shot is a shot taken by a camera on a moving crane or jib. Most cranes accommodate both the camera and an operator, but some can be moved by remote control. Camera cranes go back to the dawn of movie-making, and were frequently used in silent films to enhance the epic nature of large sets and massive crowds. Another use is to move up and away from the actors, a common way of ending a movie. Crane shots are often found in what are supposed to be emotional or suspenseful scenes. One example of this technique is the shots taken by remote cranes in the car-chase sequence of the 1985 film To Live and Die in L.A.. Some filmmakers place the camera on a boom arm simply to make it easier to move around between ordinary set-ups.

Technique

The major supplier of cranes in the cinema of the United States throughout the 1940s, 1950s, and 1960s was the Chapman Company (later Chapman-Leonard of North Hollywood), supplanted by dozens of similar manufacturers around the world. The traditional design provided seats for both the director and the camera operator, and sometimes a third seat for the cinematographer as well. Large weights on the back of the crane compensate for the weight of the people riding the crane and must be adjusted carefully to avoid the possibility of accidents. During the 1960s, the tallest crane was the Chapman Titan crane, a massive design over 20 feet high that won an Academy Scientific & Engineering award. Most such cranes were manually operated, requiring an experienced boom operator who knew how to vertically raise, lower, and "crab" the camera alongside actors while the crane platform rolled on separate tracks. The crane operator and camera operator had to precisely coordinate their moves so that focus, pan, and camera position all started and stopped at the same time, requiring great skill and rehearsal.

Types

Camera cranes may be small, medium, or large, depending on the load capacity and length of the loading arm. Historically, the first camera crane provided for lifting the chamber together with the operator, and sometimes an assistant. The range of motion of the boom was restricted because of the high load capacity and the need to ensure operator safety. In recent years a camera crane boom tripod with a remote control has become popular. It carries on the boom only a movie or television camera without an operator and allows shooting from difficult positions as a small load capacity makes it possible to achieve a long reach of the crane boom and relative freedom of movement. The operator controls the camera from the ground through a motorized panoramic head, using remote control and video surveillance by watching the image on the monitor. A separate category consists of telescopic camera cranes. These devices allow setting an arbitrary trajectory of the camera, eliminating the characteristic jib crane radial displacement that comes with traditional spanning shots.

Large camera cranes are almost indistinguishable from the usual boom-type cranes, with the exception of special equipment for smoothly moving the boom and controlling noise. Small camera cranes and crane-trucks have a lightweight construction, often without a mechanical drive. The valves are controlled manually by balancing the load-specific counterweight, facilitating manipulation. To improve usability and repeatability of movement of the crane in different takes, the axis of rotation arrows are provided with limbs and a pointer. In some cases, the camera crane is mounted on a dolly for even greater camera mobility. Such devices are called crane trolleys. In modern films robotic cranes allow use of multiple actuators for high-accuracy repeated movement of the camera in trick photography. These devices are called tap-robots; some sources use the term motion control.

Manufacturers

During the last few years, camera cranes have been miniaturized and costs have dropped so dramatically that most aspiring film makers have access to these tools. What was once a "Hollywood" effect is now available for under $400. Main producers of cranes companies include ABC-Products, Cambo, Filmotechnic, Polecam, Panther and Matthews Studio Equipment.

Famous examples

• Leni Riefenstahl had a cameraman shoot a half-circle pan shot from a crane for the 1935 Nazi propaganda film Triumph of the Will
• A crane shot was used in Orson Welles' 1941 film Citizen Kane
• The Western High Noon had a famous crane shot. The shot backs up and rises, in order to show Marshal Will Kane totally alone and isolated on the street.
• Director Dario Argento included an extensive scene in Tenebrae where the camera seemingly crawled over the walls and up a house wall, all in one seamless take. Due to its length, the tracking shot ended up being the production's most difficult and complex part to complete.
• The 1980 comedy-drama film The Stunt Man featured a crane throughout the production of the fictitious film-within-a-film, directed by eccentric director Peter O'Toole.
• The television comedy Second City Television (SCTV) uses the concept of the crane shot as comedic material. After using a crane shot in one of the first NBC-produced episodes, the network complained about the exorbitant cost of renting the crane. SCTV writers responded by making the "crane shot" a ubiquitous symbol of production excess while also lampooning network executives who care nothing about artistic vision and everything about the bottom line. At the end of the second season, an inebriated Johnny LaRue (John Candy) is given his very own crane by Santa Claus, implying he would be able to have a crane shot whenever he wanted it.
• In his film Sympathy for the Devil, Jean-Luc Godard used a crane for almost every shot in the movie, giving each scene a 360 degree tour of the tableau Godard presented to the viewer. In the final scene he even shows the crane he was able to rent on his limited his budget by including it in the scene. This was one of his traits as a filmmaker--showing off his budget--as he did with Brigitte Bardot in Le Mepris (Contempt).
• Director Dennis Dugan frequently uses top-to-bottom crane shots in his comedy films.
• Orson Welles used a crane camera during the iconic opening of Touch of Evil. The camera perched on a Chapman crane begins on a close-up of a ticking time bomb and ends three-plus minutes later with a blinding explosion.
• The closing take of Richard Attenborough's film version of Oh! What a Lovely War begins with a single war grave, gradually pulling back to reveal hundreds of identical crosses.
• The 2004 Johnnie To film Breaking News opens with an elaborate seven-minute single-take crane shot.
• The 1964 film by Mikhail Kalatozov, I Am Cuba contains two of the most astonishing tracking shots ever attempted.
