This report will focus on how different 3D technologies work, it will include the entire work flow, from recording the action, encoding the footage, playing back the media via a cinema projector or television and finally how the audience views the 3D film or video, whether it be through specially designed glasses or an auto-stereoscopic television.

At present the most popular way to view 3D media is with the use of specialised glasses, the most popular being, active shutter glasses, passive polarised glasses and colour separationbased glasses.

Wearing glasses to watch a movie is often mentioned as a negative aspect of 3D. There is a technology available that allows you to watch 3D on screens without wearing any additional glasses, it is called autostereoscopy, this will also be looked at.

The health impacts that result from watching 3D will also be examined, along with factors that will prevent a person from being able to correctly view 3D images.

There will be impacts on the entire industry from studios and cinemas to smaller production companies and independent producers if 3D films become the norm and these will be examined.

A good place to start this report is to examine how two of the highest profile media companies around at present are currently viewing 3D technology.

Phil McNally stereoscopic supervisor at Disney-3D and Dreamworks was quoted as saying,

‘…consider that all technical progress in the cinema industry brought us closer to the ultimate entertainment experience: the dream. We dream in colour, with sound, in an incoherent world with no time reference. The cinema offers us a chance to dream awake for an hour. And because we dream in 3D, we ultimately want the cinema to be a 3D experience not a flat one.'(Mendiburu, 2009)

In the BBC Research White Paper: The Challenges of Three-Dimensional Television, 3D technology is referred to as

‘…a continuing long-term evolution of television standards towards a means of recording, transmitting and displaying images that are indistinguishable from reality'(Armstrong, Salmon, & Jolly, 2009)

It is clear from both of these high profile sources that the industry is taking the evolution of 3D very seriously, as a result this is a topic that is not only very interesting but will be at the cutting edge of technological advances for the next couple of years.

This report will be covering the following things:

  • What does the term 3D mean with reference to film and video
  • A look at the history of 3D in film
  • How does 3D technology work
  • The implications of 3D on the film business and on cinemas
  • The methods used to create the media and also the ways in which the 3D image is recreated for the viewer

The reasons I have chosen to do my project on this topic is that I am very interested in the new media field.
