Stereoscopy is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word stereoscopy derives from Greek στερεός (stereos) 'firm, solid', and σκοπέω (skopeō) 'to look, to see'. Any stereoscopic image is called a stereogram. Originally, stereogram referred to a pair of stereo images which could be viewed using a stereoscope.
3D films are motion pictures made to give an illusion of three-dimensional solidity, usually with the help of special glasses worn by viewers. They have existed in some form since 1915, but had been largely relegated to a niche in the motion picture industry because of the costly hardware and processes required to produce and display a 3D film, and the lack of a standardized format for all segments of the entertainment business. Nonetheless, 3D films were prominently featured in the 1950s in American cinema, and later experienced a worldwide resurgence in the 1980s and 1990s driven by IMAX high-end theaters and Disney-themed venues. 3D films became increasingly successful throughout the 2000s, peaking with the success of 3D presentations of Avatar in December 2009, after which 3D films again decreased in popularity. Certain directors have also taken more experimental approaches to 3D filmmaking, most notably celebrated auteur Jean-Luc Godard in his film Goodbye to Language.
A stereoscope is a device for viewing a stereoscopic pair of separate images, depicting left-eye and right-eye views of the same scene, as a single three-dimensional image.
The American Civil War was the most widely covered conflict of the 19th century. The images would provide posterity with a comprehensive visual record of the war and its leading figures, and make a powerful impression on the populace. Something not generally known by the public is the fact that roughly 70% of the war's documentary photography was captured by the twin lenses of a stereo camera. The American Civil War was the first war in history whose intimate reality would be brought home to the public, not only in newspaper depictions, album cards and cartes-de-visite, but in a popular new 3D format called a "stereograph," "stereocard" or "stereoview." Millions of these cards were produced and purchased by a public eager to experience the nature of warfare in a whole new way.
Carleton E. Watkins (1829–1916) was an American photographer of the 19th century. Born in New York, he moved to California and quickly became interested in photography. He focused mainly on landscape photography, and Yosemite Valley was a favorite subject of his. His photographs of the valley significantly influenced the United States Congress' decision to preserve it as a National Park.
A 3D display is a display device capable of conveying depth to the viewer. Many 3D displays are stereoscopic displays, which produce a basic 3D effect by means of stereopsis, but can cause eye strain and visual fatigue. Newer 3D displays such as holographic and light field displays produce a more realistic 3D effect by combining stereopsis and accurate focal length for the displayed content. Newer 3D displays in this manner cause less visual fatigue than classical stereoscopic displays.
Stereopsis is the component of depth perception retrieved through binocular vision. Stereopsis is not the only contributor to depth perception, but it is a major one. Binocular vision happens because each eye receives a different image because they are in slightly different positions on one's head. These positional differences are referred to as "horizontal disparities" or, more generally, "binocular disparities". Disparities are processed in the visual cortex of the brain to yield depth perception. While binocular disparities are naturally present when viewing a real three-dimensional scene with two eyes, they can also be simulated by artificially presenting two different images separately to each eye using a method called stereoscopy. The perception of depth in such cases is also referred to as "stereoscopic depth".
Henry Hamilton Bennett was an American photographer famous for his pictures of the Dells of the Wisconsin River and surrounding region taken between 1865 and 1908. The popularity of his photographs helped turn the city of Wisconsin Dells, Wisconsin into a tourist destination.
Precursors of film are concepts and devices that have much in common with the later art and techniques of cinema.
Underwood & Underwood was a producer and distributor of stereoscopic and other photographic images, and later was a pioneer in the field of news bureau photography.
Talon was the first slide fastener, a/k/a zipper, manufacturing company. It was founded in 1893 as the Universal Fastener Company, manufacturing hookless fasteners for shoes. In 1913 it moved to Meadville, Pennsylvania, becoming the first manufacturer of zippers. The company flourished through the 1960s when it is estimated that seven out of every 10 zippers were made by Talon.
A slide viewer is a device for looking at film transparencies or similar photographic images.
Benjamin West Kilburn was an American photographer and stereoscopic view publisher famous for his landscape images of the nascent American and Canadian state, provincial, and national parks and his visual record of the great migrations at the end of the nineteenth century. Kilburn was a legislator in the New Hampshire General Court. A patent was granted for his gun-style camera.
Les Diableries is the title of a series of stereoscopic photographs published in Paris during the 1860s. The photographs, commonly known as stereoviews, portray sculpted clay vignettes which depict scenes of daily life in Hell. Much of the subject matter was satirical and mirrored the corruption and excess of Paris during the Second Empire. Napoleon III's authoritarian rule was repeatedly the subject of criticism, as was the decadent lifestyle of the bourgeoisie.
Stereo photography techniques are methods to produce stereoscopic images, videos and films. This is done with a variety of equipment including special built stereo cameras, single cameras with or without special attachments, and paired cameras. This involves traditional film cameras as well as, tape and modern digital cameras. A number of specialized techniques are employed to produce different kinds of stereo images.
John Carbutt (1832–1905) was a photographic pioneer, stereo card publisher, and photographic entrepreneur. He came to be the first to use celluloid for photographic film and to market dry-plate glass negatives.
The H.C. White Company Mill Complex, is a historic industrial complex at 140 Water Street in North Bennington, Vermont. The White Company was founded in 1879, producing stereographic viewers and stereograph cards, as well as the Kiddie-Kar, a three-wheeled wooden scooter for children. These premises were occupied by the company from then until its closure in 1935. The complex, with buildings dating from 1887 to 1919, was listed on the National Register of Historic Places in 2017.
