Nowadays, TV shows can now be watched in 3D and this can make the viewing experience more entertaining. But instead of spending for it, you can try make your own. Polarized 3D glasses brings an illusion of three-dimensional images by restricting the light that reaches each eye, an example of stereoscopy which exploits the polarization of light. There are a lot of options where to buy 3D glasses.
Basically, stereoscopic motion pictures use two images that are projected superimposed onto the same screen through different polarizing filters. This is then followed with eyeglasses that contain a pair of different polarizing filters. As each filter passes only that light which is similarly polarized and blocks the light polarized in the opposite direction, each eye sees a different image. by projecting the same scene into both eyes, the illusion is created but depicted from slightly different perspectives.
Thought the concept of 3D has been quite old, it continues to fascinate and entice viewers whether on the cinemas or at the comfort of your home.
Nowadays, movie or television shows are made to look like a 3-D scene that’s happening right in front of you. With objects flying off the screen and careening in your direction, by wearing 3-D glasses you’ll feel like you’re part of that fictitious world. Considering they have such high entertainment value, you’ll be surprised at how simple 3-D glasses actually are. You must know where to buy 3D glasses in order to enjoy it with your family.
Here, we’ll examine the two most popular types of 3-D glasses. But first, let’s understand what binocular vision is. The idea of breaking an image up into components so that the brain sees it as three-dimensional is not a new one, as evidenced by the fact that Batman comics have showed this kind of idea for several years. Still, most people don’t know how these work. So here are a few basic tips to understanding how 3D images work.
Basically, two cameras are used at all times while filming 3D scenes. By shooting two slightly different angles the illusion can be produced, which gives the 2-inch (5-centimeter) distance between the human eyes. Naturally, we are born to see stereoscopically, but our brain merges the two slightly different images from our eyes together, and lets us to see objects in 3D as “default.”
By filming the scene in slightly different angles, producers are able to produce that 3D effect. These capture the images that are then superimposed on each other. But the main trick here is the light filter used for the cameras. One of them has to shoot using a reddish filter, while the other needs to use a cyan, green or blue one. And once the show is on cinemas people are then given special lenses.
Color-coding is essential in helping the brain put the pictures back together. Each of the lenses has a certain color, but one is always red, while the other can have any of the remaining three. The light filters mean that images that have been shot by the first camera, using a red filter, will only enter the right eye, while footage from the second camera, which has been shot in green, only enters the left one. Usually, when watching 3D movies and you took your glasses off during intense scenes, you’ll notice that what appears on the screen may not seem like a good film, in that the image is completely out-of-focus. Without the special lenses, you won’t get to savor the great viewing experience.
