The impact of 3D


Cinema industries had no major upgrades in ages that would attract more viewers to the halls. They needed something new, something that could change the experience of watching films on a big screen. 3D was what cinema industries thought is going to attract bigger audiences to theaters, meaning more profit for companies, which is the main goal of any money-making company.  Even when 3D was around us for one hundred years only on 20th century it really started to grow popularity but was not widely spread just until 2009 when James Cameron Avatar (2009) was created. Avatar is hailed as one of the best three-D films made and helped to push 3D towards the mainstream. There was an option even to see Avatar in 4D, but only in South Korean theaters.



Filming in 3D is different than filming in old and popular 2D way. When filming in 2D the film cuts can be faster because the depth is short. Likewise, when making a film in 3D filmmakers have to make it a little bit different because they cannot make same cuts like on 2D film. The reason for that is that human eyes need time to focus on the depth of the 3D. ‘’Human eyes are parallel to each other and can converge inward. However, they cannot move beyond parallel, i.e. diverge from each other. To avoid this, parallax limits are adopted in camera movements.’’ (Maheshwari, 2013 para. 3). 3D is challenging for filmmakers that have been creating films in an old fashioned 2D way. A 3D film can either be made by using a camera that shoots in 3D or by converting 2D film using a software. A few other difficulties that filmmakers meet are that they need to think twice when a film has to be made in both formats 2D and 3D. If a 3D is made only by using software that converted a film from 2D to 3D it can be either a good experience or a bad one. Some of the shots that were converted by software to 3D might disturb the viewer eyes in seeing the scale and depth of the picture making the film worse when the goal was to make it better. Last difference and challenge that filmmakers come up to when creating a 3D film that they have to use two cameras instead of one, so that means everything has to be done twice for the same shot. For one scene both cameras have to be set up, both cameras have to have same settings and both cameras have to be checked to be sure if everything is in focus. However, all these problems are avoided with cameras that shoot 3D straight away. Producers got involved into the 3D wave and they did put in all the effort they could to convert films from 2D to 3D. Still, the result was disappointing. Many people thought that this new point of view will be successful but, 3D is not worth extra few pounds, as it does not make your jaw drop with its 3D effect at all. All in all, 3D was not really what films needed to grow its popularity, especially not with those films which were only converted from 2D, not like the film Avatar that was created especially for the 3D platform and achieved a huge success.


Over years 3D technology like any other technology did evolve more or less, but the thing is that it did not get surprisingly better. The first 3D glasses were the ones that we all imagine in our mind first, the ones with red and blue lenses. These particular glasses are called anaglyph glasses that produces a 3D image through anaglyph color filters. According to Snapily.com (2012, para. 3) ‘’The differently colored lenses allow our eyes to capture two different angles of an image, or two different images entirely.  The brain then merges one image with the other, resulting in a ‘popping’ effect with a unified image jumping off the screen or the photo. ‘’ The second version of glasses is called Polarized 3D glasses and was found by Edwin Land in 1936. Polarized glasses like anaglyph glasses work in same way. Snapily.com (2012, para. 4) ‘’The screen presents two images through orthogonal polarizing filters which are likewise contained in the 3D glasses themselves.’’ The only difference that is seen visually between anaglyph glasses and polarizing glasses is that instead of having differently colored lenses they are now both same clear color. Polarized glasses have a yellowish brown tint on them which blocks a different amount of light coming in through the lenses. The latest and most modern 3D glasses are active shutter glasses. These particular glasses are really different than earlier two mentioned ones before. The main difference from outside view between anaglyph and polarized ones is that shutter glasses are bulkier. The reason for being bigger is that they have batteries mounted inside them often on off button and a transmitter. Silva (2017, para. 8) states that ‘’transmitter synchs the rapidly moving shutters for each eye with the onscreen display rate. The principal of tricking brains in thinking that image is 3D is the same as other glasses, but the shutter glasses just use transmitter that requires being powered by batteries. Shutter glasses gives a better image quality that is the main advantage of them. On the other hand, it has the disadvantage that the user might notice the shutter while watching a film and that makes the experience of film worse, might even give a headache or motion sickness.



All in all, 3D has been around us for many years, as like any other technology it gets better and better each day. Having an option on how you will experience the film and how you will view it never was a bad thing. Even the small 3D effect creates a different experience in viewing the film from a different angle what is never been a bad thing.
