Breakthrough Aussie Innovation: Making 3D Movies
17 June 2010
While there has been a lot of publicity around the latest introduction of 3D movies and the accompanying 3D screens and glasses, 3D movie production is very expensive.
In fact, it comes as a surprise to most people to find that the blockbuster Alice in Wonderland was actually shot in
conventional 2D and labouriously converted to 3D later!
Now there is a new Australia camera rig, the SpeedWedge, which promises to streamline the whole process.
