They make Imax movies all over the world.

A conventional film uses 35mm film for projection whereas an IMAX film uses 70mm film for projection. This gives a greater clarity and resolution for the picture, enabling the size of the projection to be larger. The larger film size requires larger cameras, projectors, screens and viewing rooms which ups the cost of IMAX quite a chunk over conventional film.

A 3D film requires two cameras, twice as much film, two projectors and viewing glasses in order to create the illusion of three dimensions. Two cameras take slightly different images of the same shot, just as each of your eyes sees a slightly different image to produce depth perception. On playback, the images are simultaneously projected together from slightly different angles on the same screen. The left lens from your viewing glasses is polarized differently from the right so that each eye receives only one image from the screen, fooling your brain into seeing 3D.

Wanna have some fun? Look at a 3D film that is out-of-synch -- where one projector is three or four frames ahead of the other. After about ten minutes, you'll get pretty sick to your stomach.

Another answer

Once you photograph your IMAX production, you need to process the film (IMAX recommends a lab in Hollywood, probably because not many labs can work with this film because it's so wide) and turn it into a releasable movie. IMAX recommends using their own postproduction shop, which is in Santa Monica, CA.

IMAX's website is kinda fun if you're a geek. They tell you about renting their cameras (when it lands on your loading dock it's in sixteen crates), they've got a book to tell you how to make good IMAX movies.

IMAX is a motion picture film format and projection standard created by Canada's IMAX Corporation. The Company's activities include the design, leasing, marketing, maintenance and operation of IMAX film and digital theatre systems as well as the development, production, post production and distribution of IMAX motion pictures.[1]

IMAX has the capacity to record and display images of far greater size and resolution than conventional film systems. A standard IMAX screen is 22 m × 16.1 m (72 ft × 53 ft), but can vary. IMAX theatres are described as either classic design (purpose-built structures designed to house an IMAX theatre) or multiplex design (existing multiplex auditoriums that have been retrofitted with IMAX technology). IMAX screens in classic design locations range in size from 51' x 37' to 117' x 96' and IMAX screens in multiplex design locations range in size from 47' x 24' to 74' x 46'.[2] The world's largest cinema screen and IMAX screen is in the LG IMAX theatre in Sydney, New South Wales. It is approximately 8 stories high, with dimensions of 35.73 m × 29.42 m (117.2 ft × 96.5 ft) and covers an area of more than 1,015 m2 (10,930 sq ft).[3]

IMAX is the most widely used system for special-venue film presentations. As of December 2009[update], there were more than 400 IMAX theatres in over 40 countries.[4] Imax Corporation has released four projector types that use its 15-perforation, 70mm film format: GT (Grand Theatre), GT 3D (dual rotor), SR (Small Rotor), and MPX, which was designed to be retrofitted in existing multiplex theatres.[5] In July 2008, the company introduced a digital projection system, which it has not given a distinct name or brand, designed for multiplex theaters with screens no wider than 21.3 m (70 ft).

All IMAX projectors except the standard GT system can project 3D images.

Most IMAX theatres have flat, rectangular screens, but IMAX Dome theaters, formerly branded as OMNIMAX, use a GT projector with a fisheye lens to project an image on a tilted hemispheric dome screen.

Technical aspects

The intent of IMAX is to dramatically increase the resolution of the image by using a much larger film frame. To achieve this, 65 mm film stock is run horizontally through the cameras. While traditional 65 mm film has an image area that is 48.5 mm × 22.1 mm (1.91 in × 0.87 in) (for Todd-AO), in IMAX the image is 69.6 mm × 48.5 mm (2.74 in × 1.91 in) tall. In order to expose at standard film speed of 24 frames per second, three times as much film needs to move through the camera each second.

Yes, so far all types of 3D movies in theaters require glasses.


In theaters and IMAX in Disney digital 3D and IMAX 3D



It's basically the same thing. I mean they are both 3D. The only real difference is that Imax 3D is made with Imax cameras.


It doesn't really matter but Imax has better audio quality? __________________________________________________________________ It will depend whether or not the IMAX movie is an actual IMAX movie, projected from horizontal 70mm film, or just a 35mm or digital projection blown up to the IMAX screen size. Most of the IMAX 3D blockbuster movies you see (Harry Potter, Tron etc.) are not shot with IMAX cameras. Some movies, such as The Dark Knight, mix scenes shot with IMAX cameras with 35mm cameras. The larger film stock (4 times the size of a standard film frame) allows much greater detail, and will look better as a 3D movie as well. The sound is digital disc playback, and usually has the same quality as other 35mm movies. When IMAX was first introduced, it had much better sound quality than other movies houses, but now most theaters have the same quality sound.


imax movies are usually about learning about something like a documentary and regular /movies are not imax movies.

digital 3d is just plain 3D. IMAX 3D has a bigger screen. OK. the above is totally wrong, IMAX 3D now plays on regular size screens. please don't answer questions you don't know the answers to.


No. Only movies filmed as 3d will produce the 3d effect on a 3d television.


No, there are many other formats that you can watch movies, where it is in 3D.Another AnswerIMAX 3D is 70mm film with a different aspect ratio than is used on standard screens that show 35mm film.The IMAX 3D Experience is much larger, much more engaging, physically, than 3D on other screens, mostly because of its dramatically larger size relative to your eyes.The IMAX 3D glasses frame the screen in such a way that you have only black peripheral vision, engaging your brain more completely through your eyes than mental and emotional engagement available when viewing a standard screen.


IMAX has a high standard theatre quality as well as film quality. Therefore, there is no difference between IMAX 3D and the IMAX 3D Experience.Another AnswerIMAX 3D Experience plays films that are filmed with two cameras, projected with two projectors and viewed with pairs of special 3D glasses.IMAX 3D is enhanced single-camera/ single-projector films enhanced for clarity, brightness, and of course in an IMAX auditorium, spectacular sound.From IMBD, Polar Express technical details:"Film negative format (mm/video inches) -- Digital"Cinematographic process -- IMAX Digital 3-D"Printed film format:35 mm (anamorphic) (Kodak)70 mm (horizontal) (Kodak Vision 2383) (dual-strip 3-D)Aspect ratio:2.00 : 1 (IMAX version)2.35 : 1"
