Wired's LOTR III Tech Breakdown
rjjm writes "Interesting little logistics piece in Wired about the technology WETA used for for The Return of the King." Ya know, now that the Matrix hype vanished into nowhere, I'm glad the LotR hype is gearing up. I think this one will earn it.
Temperature of equipment rooms: 76 degrees

Forced perspective with a moving camera depends on moving parts of the scenery in sync with the camera. The scene with Gandalf and Frodo at the table in Bag End is a good example of this - no post production tricks at all.
Also, tricks where you film one person on a blue-screen, record the camera moves, replay the same camera move somewhere else (possibly with a scale transform) and combine the images. The post-production combining is completely trivial, but the technique is enabled by being able to track exactly where the camera is during the shot and replaying the same moves later.
