Difference Between 3D And IMAX 3D: Features and Technologies

At all times, people desperately tried to convey what they saw to others as authentically as possible. A big step in this direction was taken by mankind together with the invention of cinema. Development in this direction does not stop even now. We are constantly learning information about the emergence of new technologies in the field of cinema.

So, now more and more often from trailers for films you can hear the phrase “watch in 3D and IMAX 3D”Everything seems to be clear with the 3D format. But many still remain at a loss: what is the difference between 3D and IMAX 3D? And why is the ticket price for an IMAX movie so much more expensive?

The now-popular 3D format was patented as a way to present films back in the late 19th century. The whole trick of this technology lies in the fact that completely different images are projected onto the left and right eyes of a person. But because of the too high frame rate, we do not notice this. It is thanks to this trick that we perceive the image as three-dimensional. For shooting a simple 3D film, 35 mm wide film is used. At the same time, it should move exclusively vertically.

At the moment, 3D is a whole class of different technologies that allow you to transfer a volumetric image. Here are just a few of these technologies:

Reald 3d movies this method is as follows: at a rate of 72 frames per second, three polarized frames are projected onto each eye. In this case, the screen is silvered here. 

XPAN-D alternately the right and left parts of the glasses are darkened. All this happens at a speed equal to 48 frames per second.

DOLBY-3D Here the light is split into parts of the spectrum. Thus, each eye only picks up waves with a specific wavelength range. This option is cheaper, but the color rendition suffers.

Differences of IMAX 3D

Despite the fact that our country got acquainted with films in the IMAX 3D format quite recently, it would be wrong to call this technology new. Back in 1971, the first IMAX cinema was opened in Canada. A little later, in 1986, the first films in IMAX 3D were shown in the same place. Thus, IMAX 3D is not such a novelty.

But why then for a long time this format did not receive wide distribution, including in our country? The answer is simple. Special equipment is required to create and reproduce IMAX 3D content. So, IMAX 3D differs from 3D in the use of different types of films. And if, as we already know, in the usual 3D format you need 35 mm film, then in IMAX you need 70 mm. Now, thanks to the special technology Digital Media Remastering, it is possible to transfer data from one film to another.

In addition, IMAX 3D implies the presence of a special cinema and a special screen. IMAX (ImageMaximum) can be translated as “maximum image”. Thus, it is necessary to use huge screens here. It is precise because the viewer does not see the boundaries of the screen that the very feeling of being immersed in the action on the film is created.

The standard IMAX screen is 22 m by 16 m. Also, unlike a regular screen, this one has a curved shape. Due to the fact that the screen is large, the viewing room turns into a real panorama. The image quality in such a panorama is much better, and the detailing here will be excellent. And the number of rows in such a cinema hall cannot exceed 15, otherwise, the desired effect cannot be achieved.

Another pleasant surprise for viewers who come to watch the movie in the IMAX 3D format can be the excellent sound quality. Here it also takes on a three-dimensional shape. This is due to the fact that the sound passes through a special six-channel system. That is why it can be heard equally well anywhere in the cinema.

conclusion

Now let’s summarize. Here’s what we found out:

  • Firstly, the sound in an IMAX cinema is noticeably better, it has a three-dimensional shape. And at every point in the hall, everything will be heard equally well.
  • The number of rows in a conventional cinema is much higher.
  • The IMAX 3D screen has a curved shape and huge size, due to which the effect of immersion in the motion picture is obtained.
  • IMAX 3D tickets are much more expensive. But it’s definitely worth it.
