3D Cinema

The latest innovation in cinema and home entertainment, has been around since the early days of photography.

There are two ways of producing 3D footage.

• In-camera - this involves two lenses separated by a specific distance (known as the interocular distance) to produce the desired 3D effect in the circumstances of each shot
• Post-production 3D conversion - a painstaking method involving digitally tracing (or 'rotoscoping') every element in every frame of the movie, that needs to be either in front of or behind the screen.

There are broadly two methods for viewing 3-D movies in the cinema:

• Anaglyptic Method
• Polarisation Method
  • Circular Polarisation
  • Linear Polarisation

And in the home, there are three other methods:

• Active LCD Shutters
• Autostereoscopic
• Lenticular
