Introduction

It all began when a small group of Canadian experimental filmmakers came

together to produce a multi-screen film installation at EXPO ‘67 in Montreal.

The installation was part of a competition to create the first truly large-screen

film experience.

Over the next three years, IMAX technology was born, and its epic camera,

projector and domed screen system premiered at the Fuji Pavilion at EXPO '70

in Osaka, Japan.

What is IMAX?

IMAX stands for IMAGE MAXIMUM.

IMAX is a motion picture format withthe capacity for greater size and clearerresolution than standard movie systems.

IMAX movies have incredible clarity, even on huge screensthat are the hallmark of IMAX theaters worldwide

IMAX is all about “ON-SCREEN PRESENATION” .

IMAX is an entertainment experience so real you feel it in your

bones, so magical it takes you places you have never been.

Behind it is a world of high technology – proprietary software,

architecture and equipment pioneered by IMAX.

There are more than 837 theatres in 57 countries.

How is Imax achieved?

IMAX has the large film format.

It has six-channel sound system that is separate from thefilm.

A unique projection system that is specifically designed andcustom-built for IMAX

The theater itself which is specially designed.

IMAX camera

Conventional 2D camera IMAX 2D camera

IMAX 2D camera

IMAX developed its first 2D 15perf / 65mm film camera in 1976. To this day, it remains the highest-resolution camera in the world.

When captured with the IMAX® camera, the image projected in IMAX features approximately 10x more resolution than conventional 35mm film

delivering up to 40% more of the image than standard theatres with unprecedented crispness, clarity and colour saturation for a truly immersive experience.

IMAX camera evolution

---- Analog Age (2D) ---

Huge and heavy.

Few scenes were tough to shoot.

More Film length requirement.

Cost and maintenance was more.

--- Digital Age (2D) ---

Less weight and portable.

Convenient to shoot.(in water also)

Advanced capture technique.

Digital output.

More cost and less maintenance.

No compromise in clarity.

--- Digital Age (3D) ---

Very less weight.

High portability.

Immersive capture technique.

Unique dual lens.

Low cost and maintenance.

application based manufacturing.

Capturing methods

The IMAX custom 30-mm f/2.8 fisheye

lens offers high performance and a 150°field of view for recording images that

can be projected on a domical screendistortion free

Mirrors angled at 45° are

inserted behind the left-eyeand right-eye objectives to

direct images to the

appropriate film plane.

IMAX Film Format

IMAX screenconventional wide screen

IMAX Projectors

Laser aligned projections.

Dual projection system.

automatic image calibration.

Image enhancement.

IMAX split sync technology.

Custom user interface. Alternative content input. Custom severs. Water cooled xenon projection system. 4 types of projection system:

GT (Grand Theatre) GT 3D (dual rotor) SR (Small Rotor) and MPX.

3D Experience

First movie to use IMAX 3D digital Re-Mastering

but was not shot in IMAX 3D camera.

Later Transformers 4 was first movie to be shot in IMAX 3D camera.

But first 3D movie was “The Power of Love”on 27 September 1922.

IMAX 3D Experience has dual image projected on-screen, the left glass allows only left image and the right glass allows only

the right image as shown.

IMAX Sound

Laser aligned surround sound system.

Immersive uncompressed bass.

20- 2000Khz sound freq. can be achieved.

Continuous feedback for sound perfection.

frame to frame immersive audio sync.

IMAX films are now using the IMAX digital sound DDP (Digital Disc Playback) designed by Sonics.

The amps deliver more than 2000 watts per channel. The entire system is more than 15000 watts.

The six audio channels are fed to a 4-way JBL speaker array.

Digital Re-mastering (DMR)

A transformative process of turning an already powerful movie into a breath-taking IMAX blockbuster with unparalleled image and sound quality.

Its the main reason why IMAX has immersive experience into the movie.

ENHANCEMENT PROCESS

re-mixing of the sound.

endlessly adjusting the saturation.

contrast, brightness and.

hundreds of details in virtually every frame.

Conclusion

IMAX is an not just an entertainment experience, it is unmatched visual breath-taking and audio immersive

experience into the movie.
