La Région Centrale

La Région Centrale is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand La Région Centrale rather than just read about it. In short: La Région Centrale is a 1971 experimental Canadian film directed by Michael Snow. The film is 180 minutes long and shot over a period of 24 hours using a robotic arm, and consists entirely of preprogrammed movements.

Key takeaways

  • La Région Centrale belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect La Région Centrale to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of La Région Centrale from memory before moving on to harder problems.

Reference excerpt

La Région Centrale is a 1971 experimental Canadian film directed by Michael Snow. The film is 180 minutes long and shot over a period of 24 hours using a robotic arm, and consists entirely of preprogrammed movements.

Description La Région Centrale is three hours long, composed of seventeen shots of an uninhabited mountainous landscape. Between each take, the screen is black with a white X in the center. In the beginning, the camera moves to capture its surroundings with slow, continuous gestures. Over the course of the film, the movement crescendos as the camera spins rapidly.

Development Snow had the idea in 1964 to create a film where a camera moved "in every direction and on every plane of a sphere". During the late 1960s he created three films that experimented with camera movement: Wavelength, Standard Time, and <--->. He researched machines that could automatically move a camera in complex ways, particularly surveillance devices. The Canadian Film Development Corporation gave Snow a grant of $28,000, and he received additional funding from the Famous Players chain of theatres. At the recommendation of IMAX co-founder Graeme Ferguson, Snow contacted Pierre Abbeloos, an engineer at the National Film Board of Canada. He commissioned Abbeloos to construct a "Camera Activating Machine" (CAM), a robotic arm on which a 16 mm camera could be mounted. Abbeloos took a year to design and build the device. To generate a control signal for the CAM, Abbeloos used the selsyn from the Arriflex 16ST camera and converted it into a spectrum of frequencies sent to the CAM's control box. This operated the camera's zoom and determined the CAM's motion through a series of tones.

Production

Snow wanted to film a location with no traces of human activity. He originally considered the countryside north of his mother's birthplace of Chicoutimi in Saguenay, Quebec as well as Kapuskasing or Timmins, both mining areas that his father had surveyed in Northern Ontario. He scouted northern Quebec and found a mountain 160 km (100 mi) north of Sept-Îles. Snow shot La Région Centrale from September 14 to 20, 1970 with his wife Joyce Wieland, Abbeloos, and Bernard Goussard. They chartered a helicopter to transport them to the mountain. Snow and his team were shooting for five days, producing sixty hours of footage. He edited the film during a residency at the Nova Scotia College of Art and Design. For the film's soundtrack, Snow wanted to use the tones that controlled the CAM. He found it difficult to record the sound directly onto film in sync with the image; instead, he used a modified Revox to record the tones coming from the CAM's control box on quarter-inch cartridges. He dubbed the sound in post-production.

Release La Région Centrale was released in 1971. At the National Gallery of Canada, the film was exhibited along with the CAM, to which Abbeloos added a CCTV camera. The CAM responded to passersby with a 30-minute sequence of pre-programmed movements. When the film was shown at the Center for Inter-American Relations in 1972, Snow presented the modified CAM as a video sculpture titled De La.

Reception and legacy Jonas Mekas wrote that it was "curious how…'The Central Region' works totally mechanically, with computerized camera movements, and comes up with an unmistakable personal style". Wyndham Wise commented,

"In a brilliant convergence of form and content, camera movement becomes the reason d’etre. Rarely, if ever, has a film so clearly delineated the role of this machine in our reception and perception of the objected filmed. To make the film, Snow worked with a technician to design a mechanized camera that was able to move without human intervention in every direction imaginable. To further erase the influence of humans, Snow filmed in the remote reaches of Northern Quebec, where his camera roamed the landscape, in a manner both systematic and arbitrary. It’s both an exhilarating celebration of cinema’s unique qualities and a clever joke on the landscape tradition in Canadian art." J. Hoberman ranked La Région Centrale as the second best film of the 1970s. It received five critics' votes and two directors' votes in the 2012 Sight & Sound polls of the world's greatest films. The film is now part of Anthology Film Archives' Essential Cinema Repertory collection. Jean-Luc Godard repurposed the film's title for a section of his 2018 essay film The Image Book examining depictions of the Arab Maghreb in cinema.

Worked examples

Example 1 — a first encounter with La Région Centrale

Start with the simplest possible case. Write down what La Région Centrale claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to La Région Centrale before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about La Région Centrale ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of La Région Centrale

In research
La Région Centrale appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses La Région Centrale in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
La Région Centrale is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1970s avant-garde and experimental films, 1971 Canadian films, 1971 documentary films, so understanding it makes those chapters shorter.
In everyday life
Look for La Région Centrale outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
