how is a 3d movie shot ?

Question

just saw superman returns yesterday, the 3d parts of the films were amazing was wondering how is these 3d shots done, are they shot using 3 cameras or something ? what is the technology behind it

Answer 1

the term 3-D (or 3D) is used to describe any visual presentation system that attempts to maintain or recreate moving images of the third dimension, the illusion of depth as seen by the viewer.

The principle involves taking two images simultaneously, with two cameras positioned side by side, generally facing each other and filming at a 90 degree angle via mirrors, in perfect synchronization and with identical technical characteristics. When viewed in such a way that each eye sees its photographed counterpart, the viewer's visual cortex will interpret the pair of images as a single three-dimensional image.

New technologies are coming that will allow current 2-D films to be remastered into 3-D using proprietary procedures. George Lucas has announced that he will re-release his Star Wars films in 3-D based on a conversion process from the company In-Three.

James Cameron (Titanic) will shoot his new films Avatar and Battle Angel in digital 3-D. Filming will use HDTV cameras and the Fusion Camera system.

Animated films Open Season, Monster House, The Ant Bully and Happy Feet, scheduled for upcoming release, will be released in either digital in a few hundred theaters along with a 2D release or in IMAX 3D along with regular 2D 35mm.

Both digital and IMAX are quite costly ways of showing 3D. Another approach being proposed is the upgrading of existing 35mm to show 3D with a six perf pull-down in the projector. Advocates of this, CINE 160 3D, point to 10 to 1 cost savings and proven results with film. (The film image is 1.6 times the conventional frame size.)

In late 2005 Steven Spielberg told the press he was involved in patenting a 3-D cinema system that does not need glasses, and which is based on plasma screens. A computer splits each film-frame, and then projects the two split images onto the screen at differing angles, to be picked up by tiny angled ridges on the screen. (Spielberg is co-producer of the film "Monster House".)

Even episodic TV series are embracing 3-D, as an episode of NBCs Medium hit the home HD screens in anaglyph 3-D on November 21, 2005.

In 2005, Super78 Studios was nominated for a VES award for its 3D film Curse Of Darkastle.

Answer 2

3-D shots are done using two different cameras spaced slightly appart (one for each eye). This link may help clarifiy how this is done:
