SuperD, Dolby3D, IMAX. In such an abundance of terms it is easy to get confused. RealD 3D - what is it? Once we watched cartoons drawn on paper or molded from plasticine. And we were glad about it. But modern viewers need something more serious. Therefore, the greatest film companies regularly develop new technologies to achieve the most impressive picture on the screen.
3D Movie General Information
Probably every schoolchild knows what 3D is all about. But the answer to the question, what is RealD 3D, is somewhat more difficult to answer. 3D we call three-dimensional or stereoscopic image. The image may also be two-dimensional. Remember the Egyptian drawings in profile? They are two-dimensional, that is, flat. Let’s take a look at our own eyes.
Human vision is stereoscopic. When we watch the news on TV, we observe a two-dimensional image. When we look around us, we see a three-dimensional, three-dimensional image. How it works? Our eyes see a slightly different picture. Try to close your left eye, you will not see with your right eye what you saw a second ago with your left. And, accordingly, vice versa.
One image enters the left eye, the other to the right. Then our brain combines this all into one volumetric image. 3D technology is based on this principle: to make a picture so natural, as if we are seeing it live. Some complement the effect of the presence of wind, drops in the face or odors. It’s enough to recall watching movies in the so-called 7D cinemas.
RealD 3D - what is it?
The creator of the technology is RealD Cinema, which was established in 2003. Sony has exclusive rights to this technology. That is what we mean today by 3D cinema. The essence of the technology is that when we put on 3D glasses in the cinema, we get the effect of our own binocular vision. Lenses and special projectors transmit us a picture separately on the left and right eyes. Therefore, it seems that all the objects in the movie are flying into our faces.
But what is it - RealD 3D? A feature of the technology is the so-called circular polarization, which provides a good visual effect from all viewing angles and allows us to change the position of the body while watching a movie, tilting our head. The image for the left eye is projected clockwise. For the right - on the contrary. Because of this, the technology was called circular. In this case, the image will not disappear on the periphery. Actual, for example, for children when they watch cartoons.
Technical description IMAX 3D
IMAX 3D technology, developed in 1970 by the Canadian company Multiscreen, works on the same principles, but there are significant differences. First, instead of circular polarization, there is a linear polarization method. On the one hand, this limits the review. On the other hand, with this technology, the image is clearer and brighter.
The second difference is the scale of the screen. This is a unique, curved screen, which is wider than the hall itself. That is, the audience is as if inside the image. This compensates for the limited visibility of linear polarization. Another plus of the IMAX format is that it is accompanied by audio equipment of a certain class and quality, so the sound here creates an extraordinary effect. To broadcast films in this format, two projectors are required.
RealD 3D or IMAX 3D: which is better?
Before watching a movie, many people think that this is RealD 3D for a cunning abbreviation. Isn't it better to choose an IMAX cinema? It is quite difficult to answer this question, since both technologies have their advantages. In addition, they are constantly improving and developing. In some cases, the choice will depend on the nature of the movie you are about to watch. It will be interesting to watch more epic and full of effects and 3D-graphics films on a huge IMAX-screen.
Horror movies, on the other hand, may not be the best idea to watch in IMAX. RealD 3D, in turn, is more convenient for viewing with children. In any case, there is no definite conclusion, much depends not only on the chosen format, but on the quality of equipment in a particular cinema. In cases where the glasses are not serviced correctly and do not change on time, the impression of the circular RealD 3D can be even more limited than with a linear but high-quality IMAX.
What do people say?
RealD 3D - what is it? Reviews about the cinema that uses this technology will help answer this question. However, the opinions of people here are fundamentally different. Someone strongly scolds the quality of RealD 3D movie theaters, preferring wide IMAX screens. According to others, the whole problem is in poor-quality glasses. After watching movies in IMAX 3D format, people often complain of severe dizziness and strain on their ears (due to the characteristic powerful sound). Many mothers do not want to bring children here.
Speaking of the detrimental effect on vision, someone is ready to completely abandon watching movies in a similar format. Judging by objective reviews, you just need to compare the sensations in both formats to make a choice for yourself. In the near future, of course, film companies will please us with improvements and new interesting technologies.
