3D movies, and live broadcasts and television studio with the equipment used in 3D theaters and homes are without doubt in the public opinion here in 2011. But despite the current S3D (3D stereo) the technology is new, the history of 3D motion pictures goes back more than a century.

Around the turn of the 20th century, the British film pioneer William Friese-Greene filed a patent for a process of dual-projector 3D film. Frederick Eugene Ives subsequently proposed a stereo camera platform with 1.75in length lenses.

In 1915, Edwin S Porter and William Waddell E 3D test reel shown to an audience at the Astor Theatre in New York. But this proved a dead end. The first commercial 3D film seems to have been demonstrated in September 1922 to an audience in Los Angeles, and during the two years following a series of short, using a variety of different 3D technologies shown in cinemas.

Stereoscopic 3D and still images

There are several basic approaches to stereoscopy, including:

Freeviewing - seeing a couple of images without a viewfinder, which means viewers to cross or diverge the eyes to get the images to match the illusion of depth.

Stereographic cards and the stereoscope - the stereoscope and reduces eye strain by using a magnifying lens, the image appears larger and more real.

Viewers of transparency - in the 1930s, manufacturers launched viewers designed to work with stereo pairs transparency. A decade later, an improved version of the technology was launched, the success and longevity View-Master.

3D film technology

Polarization - In early 1930, Edwin H. Earth was producing its first products under the Polaroid brand polarized, and saw the possibilities of stereoscopic applications. Two synchronized copies of the film were projected using a special motor selsyn in a silver screen - polarized 3D movies do not work in a regular white screen.

Between 1936 and the beginning of World War II, filmmakers in Europe and USA use the technologies of the earth.

Anaglyph - family glasses with lenses of red and green or red and blue cardboard mounted surrounds are typical of the technology used in the first Anaglyph 3D movies in the 1950s. Later in the decade, films bias embraced the technology as an alternative of better quality, and rebirth in 3D for 80 to 90 years also opted for polarizing glasses as the user interface.

Stereo 3D (S3D) - two normal HD cameras are in approximately the same distance as human eyes - sometimes more, sometimes less, depending on the shot. Digital post-production allows the director of publishing and other evolve the program. S3D projectors and televisions ended S3D decrypt the data and display the images on the screen. Today, the most common display technology uses polarized glasses to view stereoscopic images, but you can use anaglyph glasses or active. Without glasses technology is being developed.

3D films into the mainstream

3D films into the mainstream in the 1950's with the color characteristics in the first place, although the earliest examples of black and white back in late 1940. While 3D movies were important in American cinema over the decade, the process proved too expensive and the results too uncertain to support 3D in the mainstream.

Later, during the 1980's and 90's, IMAX and Disney themed sites, and 3D brought to light for film and specialized presentations based on technology with active glasses synchronized with the 3D software.

It was not until after the turn of the millennium for 3D movies to return to the mainstream, using current technology Stereo 3D can be equally applied in broadcast applications and home theater. Ten years into the new millennium, we are able to see many mainstream films in 3D in our local theaters, and buy 3D TVs in every street.

3D seems here to stay once.
