About 3D Movies And 3D Technology Used In Movies

As far back as the late 1800s, 3D technology has been used to try to entertain the masses. Things have moved on a lot over recent years however. Where just a few years ago we had to be happy with flimsy red and blue full-hd-3d, making a nauseating image, things have now changed. New developments and refinements mean we can now really look forward to dazzling movies. Here’s a quick guide about 3D movies and 3D technology used in movies.

How a 3D movie gets to the screen is essentially quite easy; requiring nothing more than presenting the audience with two different views of the same scene. When shooting, this requires two cameras, set slightly apart from each other but shooting the same action.

As with older techniques, the audience is still required to wear glasses to present the full 3D experience, through the use of polarizing filters. This essentially affects the light wave being emitted from the screen, and controls how it is delivered to the viewer in respect of the direct of travel.

Polarization is quite a difficult concept to understand, but because it works on the light wave itself, rather than the lengths which affect the color, those colored glasses of the past are no longer needed.

There are two forms of polarization which can be used: linear or circular. 3D-MoviesLinear polarizing techniques are good, and cheaper to implement, but do not provide as full an experience. As the name would suggest, there needs to be a constant line of sight from screen to the audience member to deliver the best image. One slight move off this line, and the quality will be affected.

Circular polarization delivers a far better product, as it works with the viewers movements. There is still a need to maintain a certain posture throughout, but variances like tensing of the jaw, off center head position and so forth are far better accommodated.

The technology today is far better than it once was, but things will not rest here for long. Already companies are working on tech where the polarizing filters sit in front of the screen, removing the need for glasses at all. For many movies, this is far better of course, though for those watching UP, the stylized glasses of the main character was a bonus.

The beauty about movies and 3D technology used in movies is that the audience becomes absorbed into the presentation far more. From Avatar to Piranha 3D, the technology is really moving on now, so we an expect a lot of films to be remade over the next few years.
