prolific inventor and entrepreneur

Cameras At the research labs of prolific inventor and entrepreneur Thomas Edison, William Dickson developed a camera that captured 16 images per second. It was the first workable motion picture camera. Dickson used celluloid film perfected by George Eastman, who popularized amateur photography with his Kodak camera. By 1891, Edison had begun producing movies.

Projectors Edison’s movies were viewed by looking into a box. Edison recognized the commercial advantage in projection and patented a projector called the Kinetograph in the early 1890s, and later, the Kinescope. Edison’s inventions used Eastman’s celluloid film, and were debuted with a short film in 1893. Inspired by Edison’s projector, French brothers Auguste and Louis Lumière brought projectors to motion pictures. By running the film in front of a specially aimed, powerful light bulb, the Lumières projected movie images onto a wall. In 1895, they opened an exhibition hall in Paris—the first movie house.

Media Tomorrow 3-D: Next Big Thing?

Jeffrey Katzenberg. He’s been called the Evangelist of 3D. Indeed, as Jeffrey Katzenberg notes, 4 of the 10 films released in 3D in 2010 ranked among Hollywood’s top moneymakers. Expect 3D TV to blossom next, he says.

A newer technological development is called three-dimensional stereoscopic film, or 3D. As chief of Hollywood movie maker DreamWorks Animation, Jeffrey Katzenberg has been in the vanguard promoting 3D films, not only in movies but also in television, video games, and cell phone screens as well (even billboards!). To Katzenberg, all our media of the future will be seen through the illusion of 3D— except, of course, radio and other sound-alone media.

Just after Christmas 1922, Cornell University inventor Laurens Hammond showed Radio-Man—the first commercial 3D movie. Hammond enhanced the illusion of depth perception by flashing two slightly offset images simultaneously, one for the right eye, one for the left. The technology, called stereoscopy, had roots almost a century earlier with 3D illusions imposed on still photography. Despite Hammond’s breakthrough work with Radio-Man, he ran into an obstacle. Only one theater, the Selwyn in New York, was equipped with special projection and viewing devices needed for 3D. Radio-Man had a short run, although it was later released in 2D. As movie technology, 3D quickly became dormant.
