Understanding The Techniques Behind Your Favorite 3D Film
The 3D film market has grown immensely in the past few years, and what was once a rare specialty is now commonly seen in many theaters. Film makers have been toying with 3D movies since the 1950's when producers first started finding ways to add depth to their motion pictures; modern artists have many more tools, however, than were available 60 years ago. By using special filming and presentation techniques and equipment, film makers are able to trick your eye into believing that a plain movie screen is actually projecting three dimensional images when you watch a 3D film.
The basic concept behind creating a 3D film is recording the images the same way your eyes see them, using information gathered from both the left and right eye to create one image; this is called stereoscopic vision. The cameras used to record 3D movies are made with two lenses which are placed next to one another much like your eyes. When a movie is developed totally using computers, such as Avatar, the 3D effect is achieved by adapting the animation process to incorporate stereoscopic vision. The two videos captured by each lens are projected simultaneously onto the movie screen and, using specially designed glasses, are put together by your brain to create a three dimensional image.
Blue and red 3D glasses were used for many years whenever a person wanted to watch a 3D film. These glasses work because the two images fused to create a stereoscopic film were sent through a red light filter and a blue light filter, which can combine when you wear the 3D glasses. The limitations caused by this system moved film makers to seek out better technology.
Vibrating light waves moving on one plane, called polarized light, is how we watch 3D movies today. Though you just see one image, there are actually two projectors sending out one vertically and one horizontally polarized image during the 3D film. The 3D glasses you wear filter out certain types of light so that only horizontal waves can enter your left eye and only vertical ones can be viewed by your right eye. The resulting optical illusion makes your brain process two images as just one but also creates the realistic depth that audiences love so much about modern 3D movies.

Many people choose DIY methods because they are worried about kitchen remodel cost overruns. They believe that if they take complete control of the job they will not have to spend a dime more than their budget.
