Since the launch of James Cameron’s 3D film, Avatar, it’s got everyone talking about 3D technology. When it comes to box office returns, no other film comes close to matching Avatar. The 3D film raked in a cool $2.7 billion (£2.2 billion), with nothing but sensational visual effects.
Cameron started writing the film in 1994, however was unable to develop the plot further until the technology had advanced enough.
RealD is a digital stereoscopic projection technology made and sold by RealD. It is currently the most widely used technology for watching 3D films in theatres. RealD produces technology to trick our eyes into perceiving projected the images as three-dimensional or somewhat leaping out of the screen at us!
RealD vs. IMAX: How Does It Work and What Is The Difference?
IMAX is still the most well-known 3D format. Both RealD and IMAX utilise passive 3D technology, which means you wear lightweight eyewear. These passive 3D glasses use polarizing filters to allow each eye to see a slightly different image. RealD 3D technology is optimised to allow you to turn and tilt your head without losing the effect.
Both these technologies are digital. So subsequently, you’ll get a clean image and none of the image noise or “cigarette burns” that are visible from regular film projectors.
RealD’s 3D format is natively digital. Therefore, films are filmed using 3D cameras and projected through a 3D digital projector, which polarises each frame. Passive circular polarizing techniques are also used to create 3D films. This allows viewers a clear image even when turning or tilting their heads.
IMAX Digital 3D
As we mentioned before, this is the most well-known 3D film format. IMAX cinema screens are well known for their huge, curved screens. IMAX Digital 3D is an evolution of the analog IMAX 3D theaters that have been around since the 1980’s.
Unlike Real3D, IMAX views have to refrain from any head movements. Although this is probably unavoidable due to the massive curbed screen.
It’s All In The Detail
The silver-coated screens make them 85% brighter than a standard screen. 3D films instantly appear sharper with so much more clarity. The anti-stick coating is resilient to dust, coins and nachos being thrown at it.
3D Film And The Future
RealD has created technology which enables the user to take control of this light field that comes from a device and control where it is directed. The result is the ability to create 3D effects on a screen without the need for 3D glasses. RealD is looking to incorporate InteliLight technology into devices in the near future.
