New tendency in cinema industry is so-called 4D/5D films. They are quite trendy now, but let’s avoid any misunderstanding and say a few words about what 4D/5D movies are. Funny, but to explain this thing, we should start with explanation of 3D film term.

  So, 3D film is a movie, where viewer can see sort of three-dimensional object instead of plain image how a scene looks in a usual film. It allows authors of the film to make an action not only in the plane of a screen, but to show some elements nearer (or further) to (or from) a viewer or even make them move to or from them. That’s how 3D technology works and this effect is based on co-called human’s binocular vision. It means that a human sees with two eyes, therefore brain can register an action in three dimensions. So, film’s authors give the viewer two different pictures for each eye (how it can be done is another topic though, there are lots of methods actually), therefore the viewers’ brain can interpret the movie scene as a 3D object.

  To summarize, when you sit in the cinema and see a movie with 3D scenes, this film is a 3D one. When you sit in the cinema watching 3D film and your chair moves in some moments of it, this is 4D movie. Also, the cinema can reproduce the effects of wind, rain etc, when it happens in the film, it’s also 4D-effect. However, some cinema companies call moving platform effect 4D, but wind, smoke, water etc effects as 5D. Actually, it is just a marketing trick, but at least it allows us not to call 5D as 4D and 4D as not-exactly-4D-but-still.

  There is question, what 3D/4D/5D movies are? Is it a new form of art or  is it just a new thing to have more fun (and consequently to earn more money for cinema companies)? To answer this question, let’s think about how the first films came. Initially, when Lumiere brothers created their films, it meant two facts: it was really interesting for viewers and it was a new technology. I don’t think that "L'Arrivée d'un Train en Gare de la Ciotat” (or earlier Lumieres’ movies) is kind of art, it was just a way to test the technology, but it was still state-of-the-art that time. It was incredible and unusual in those days. After that, when this technology started growing up and people started using it to release their own art ideas, which could not be released another way, the cinema art came.

  So, 3D/4D/5D technology is just an instrument for smart guys to explain their ideas to viewers. It just widens up the possibilities of creator. It means that it will help both: art and business. It means that on the one hand we will get more fun seeing next comedy or thriller (there is no accounting for taste) and on the other hand we will see new art films, where 3D principle helps us to understand the creator.
