Between 1890 and 1920, several tests were performed with 3D film systems, but due to the complexity of the mechanism, it was not successful. In 1922, the first photographically applied 3D film arrived in Los Angeles. Robert F. The cameraman Elder and Harry K From the hand of producer Fairall. A double projection method was used, dividing the image into two colors, red and green; each color had its effect on two eyes. The film The Power of Love was unsuccessful, and if added to this equation was the fall of Wall Street in 1929, it was a three-dimensionality cut – although the Nazis also used 3D films as propaganda by Joseph Goebbels.

We had to wait until 1934. The well-known Goldwyn Mayer Metro successfully presented several shorts of this kind, and in Europe Louis Lumière presented the famous arrival of the Train in a 3D room. It was then that this format was introduced into society.

Since then it had hardly any importance and gradually lost strength, although they created the IMAX system and some new experiments and formats. But in 2009, Avatar was premiered by director James Cameron. Putting aside the film's assessment, the film managed to tighten this system and that relationship between the general public. In addition to the cinemas, he managed to get the home TV and 3D mold out of hand. Many manufacturers, like crazy ones, started putting this system in their products. Gradually it spread in our day to day, but in a very wrong way. They imagined it as a floating currency and as an excuse to push people into cinemas. Running and in a hurry they passed a lot of 3D films, considerably raising the price of the tickets. "Here's the business! they thought. But they didn't realize one very important thing: that you can fool people in the short term, but in the long run they would realize the veneer.

And so it has happened. In 2015, this fraudulent system gradually collapses, just as fat sugar in coffee does. He's dying. From the mouths of several companies there are only cries of pain saying that they are not going to give more support to this system. I am sure that, if it continues like this, in a few years' time it will disappear completely, or as it happened before, it will remain in a second plano.Porque they are just an artificial fire, spectacular but totally empty inside, a disaster after all - with the exception of two or three films like Gravity and Hugo.

In addition to this disaster, there's a curiosity that many people don't know. That not everyone can see in 3D. Why? By transmitting this way, two images are created at a time, sending the image to the lens. It separates them so that each eye sees one. At that time, a process called binocular fusion occurs in the brain, bringing together images and creating a three-dimensional sensation. It is precisely the people with difficulties in performing this binocular fusion that do not have the ability to see this system. Because images don't reach the brain properly.

To conclude and conclude with a more positive counterpoint, will this system someday be useful? Of course, yes! It's the film element when it comes to writing the script. That is, as the kind of plane, color, the work of the actors or music are essential, when 3D is given the same importance and not as mere spectacle. So let's imagine that in this way, we take that three-dimensionality away from an ingrained movie. If difficulties arise at that time in understanding the film or in following the story, then that is when this system will be valid and will definitely remain among us. Then we will say: 3D? Yes, thank you!
