IMAX provides an immersive movie experience through large format film and specially designed theaters. It uses a high resolution camera that captures more of the image than standard formats. Films are projected onto very large screens using advanced projectors and surround sound systems. The specially designed IMAX theaters, with large curved screens and advanced audio, are intended to make audiences feel as though they are part of the on-screen experience.

3. 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.

4. What is IMAX?
 IMAX stands for IMAGE MAXIMUM.
 IMAX is a motion picture format with
the capacity for greater size and clearer
resolution than standard movie systems.
 IMAX movies have incredible clarity, even on huge screens
that are the hallmark of IMAX theaters worldwide

5.  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.

6. How is Imax achieved?
IMAX has the large film format.
 It has six-channel sound system that is separate from the
film.
 A unique projection system that is specifically designed and
custom-built for IMAX
 The theater itself which is specially designed.

8. 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.

9. IMAX camera evolution
---- Analog Age (2D) ---
 Huge and heavy.
 Few scenes were tough to shoot.
 More Film length requirement.
 Cost and maintenance was more.

10. --- 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.

11. --- Digital Age (3D) ---
 Very less weight.
 High portability.
 Immersive capture technique.
 Unique dual lens.
 Low cost and maintenance.
 application based manufacturing.

12. 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 screen
distortion free
Mirrors angled at 45° are
inserted behind the left-eye
and right-eye objectives to
direct images to the
appropriate film plane.

15. IMAX Projectors
 Laser aligned projections.
 Dual projection system.
 automatic image calibration.
 Image enhancement.
 IMAX split sync technology.

16.  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.

17. 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.

18. 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.

19. IMAX
Sound

20. 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.

21.  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.

27. 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.

28. Conclusion
IMAX is an not just an entertainment experience, it is
unmatched visual breath-taking and audio immersive
experience into the movie.
