Stereoscopy Imaging in 3D or how to enter into the image Pau Comes del Mazo

Basics Stereoscopic or binocular vision was invented by nature hundreds of millions of years ago. The human eyes provide the brain with two independent, slightly different images of an object called stereo vision. This process leads to the sensation of depth enabling us to determine how close or far an object is.

History The stereoscopic era of motion pictures began in the late 1890s when British film pioneer William Friese-Greene filed a patent for a 3-D movie process. In his patent, two films were projected side by side on screen. The viewer looked through a stereoscope to converge the two images. Because of the obtrusive mechanics behind this method, theatrical use was not practical. Timeline: - Early systems of stereoscopic filmmaking (pre-1952) -The "golden era" (1952–1955) -Revival (1960–1984) in single strip format -Rebirth of 3-D (1985–2003)- -3-D re-enters mainstream cinema (2003–present)

New trends in Electronics market New 3D revival Youtube 3D Channel “After Toy Story, there were 10 really bad CG movies because everybody thought the success of that film was CG and not great characters that were beautifully designed and heartwarming. Now, you've got people quickly converting movies from 2D to 3D, which is not what we did. They're expecting the same result, when in fact they will probably work against the adoption of 3D because they'll be putting out an inferior product. ” — James Cameron
