The 3D film market has grown quite a bit in the past few years, and what was once a rare specialty is now commonly seen in many theaters. Although the idea of 3D films has been around since the 1950's, it was not until very recently that technology has truly caught up with the imagination of film makers and producers who try to create a visually immersing world for their audiences. By using special filming and presentation techniques and equipment, film makers are able to trick your eye into thinking that a plain movie screen is actually projecting three dimensional images when you watch a 3D film.
Humans see using stereoscopic vision, combining images taken in from both our eyes to create one total picture, and this is exactly what a 3D film aims to do. Two side by side lenses are used in cameras when filming a 3D movie so that they can capture images similar to the way your eyes do. Movies created with computer technology, like Avatar, can also be produced in the same way to create a stereoscopic film. When you watch a 3D movie, you are actually looking at both of the images captured by each camera lens at once; wearing special 3D glasses is what allows you to process both images at the same time.
Many people are familiar with the first 3D glasses that you had to wear to see a 3D film; one side was red, one side was blue. These glasses work because the two images combined to create a stereoscopic film were projected 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 urged 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 only see one image, there are actually two projectors sending out one vertically and one horizontally polarized image during the 3D film.
Your 3D glasses prevent one type of light wave from entering each eye so that your left eye sees only horizontal waves and your right only sees the vertical ones. 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.
