What is IMAX?

IMAX is the largest and most exciting filmformat in the world!

With crystal clear images, ten times larger

than traditional cinema format, the IMAXexperience draws you in with pictures so real

you want to touch them, so powerful you can

feel them. The IMAX experience takes an image rich in

clarity and definition, throws it onto the

world's biggest screens and wraps the viewerin digital surround sound.

Using state-of-the-art electronic headsets,

complete with infra red sensors to detect the

left and right eye images, the IMAX 3D

experience has brought 3D enjoyment a long

way from the cardboard glasses of the 1950s.

Bigger images. Better sound. Sharper 3D. The

IMAX experience is the future of film

entertainment.

The screens in IMAX Theatres are the biggest

in the world.

Up to eight storeys high, they are ten times

larger than a traditional cinema screen and

fill the whole field of human vision.

Made of stretched vinyl, coated with a

reflective silver paint they are stretched taut

over a scaffold frame.

With thousands of small perforations they

allow sound from speakers positioned behind

the screen to play their key role in the total

surround sound system.

Sound is critical to the IMAX experience. The film

soundtracks are delivered through a mighty 15,000 watt

digital surround sound system manufactured by SonicsAssociates Inc, one of the world leaders in sound system

design.

The IMAX six channel, high fidelity, motion picture sound

system with sub bass plays off three separate CDs eachcarrying two tracks.

To eliminate variations in volume and sound quality over

the theatre seating area the Sonic Proportional Point

Source Loudspeaker system, specifically designed for IMAXTheatres, is used to control sound.

To project such large films IMAX have built the most

advanced, high precision and powerful projectors.


6/19

IMAX films are shot and projected on 15

perforation/70mm film - the largest film format in

existence. It is only possible to project these onto the

huge screen because of the remarkable high definition

and clarity of these film frames.

And it is these huge film frames that are at the heart of

the IMAX experience. Three times larger than the

traditional 70 mm cinemascope frames they have pushedthe quality of motion picture images to new heights (quite

literally).

IMAX Corporation ("IMAX"), founded in

1967 and headquartered jointly in New

the world's leading entertainment

technology companies, specializing inimmersive motion picture technologies.

The Companys activities include the

design, leasing, marketing, maintenance,

and operation of IMAX theatre systems,

as well as the development, production,

post-production and distribution of IMAX

motion pictures. IMAX commits significant

funding to ongoing research anddevelopment and has developed a digital

projection system which provides

consumers with the premium IMAXex erience the have come to know,

the theatres are located in North America, while the remaining 35 percent are spread

internationally. More than 60% of the theatres are part of commercial theatre complexes. The rest

are located in institutional venues, such as museums and science centers. The majority of IMAX

theatres are equipped with IMAX 3D technology. IMAX's Digital projection system began its roll

out in July, 2008. There are currently [50] digital projection systems in operation.

The dome system, which the San

Diego Hall of Science called

OMNIMAX, uses a fisheye lens onthe camera that squeezes a highly

distorted 180 degree field of view

onto the 70 mm IMAX film. The

lens is aligned below the center of

the frame and most of the bottomhalf of the circular field falls beyond

the edge of the film. The part of the

field that would fall below the edge

of the dome is masked off. When

filming, the camera is aimed

upward at an angle that matches

the tilt of the dome. When

projected through a matching

fisheye lens onto a dome, theoriginal panoramic view is

PROJECTOR AND SCREEN

To project such large films IMAX have built the most

advanced, high precision and powerful projectors.

IMAX films are shot and projected on 15

perforation/70mm film - the largest film format inexistence. It is only possible to project these onto the

huge screen because of the remarkable high definition

and clarity of these film frames.

And it is these huge film frames that are at the heart ofthe IMAX experience. Three times larger than the

traditional 70 mm cinemascope frames they have pushed

the quality of motion picture images to new heights (quite

The key to their superior performance and reliability is theunique ''Rolling Loop'' film movement. The Rolling Loop

advances the film horizontally in a smooth, wave-like

motion. During projection, each frame is positioned on a

fixed registration point and the film is held firmly againstthe rear element of the lens by a vacuum. As a result, the

picture and focus steadiness are far above normal

standards and provide outstanding image clarity.

The powerful 3D projector uses two 15,000 watt bulbs(the average 35mm projector uses a bulb between 2,000

and 4,000 watts). The huge heat generated requires a

dedicated cooling system that pumps 1,600 cubic metres

of air and 36 litres of distilled water through the lamp

housing every minute to keep the projector cool.
