Stereo Card
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. A typical stereoscope provides each eye with a lens that makes the image seen through it appear larger and more distant and usually also shifts its apparent horizontal position, so that for a person with normal binocular depth perception the edges of the two images seemingly fuse into one "stereo window". In current practice, the images are prepared so that the scene appears to be beyond this virtual window, through which objects are sometimes allowed to protrude, but this was not always the custom. A divider or other view-limiting feature is usually provided to prevent each eye from being distracted by also seeing the image intended for the other eye. Most people can, with practice and some effort, view stereoscopic image pairs in 3D without the aid of a stereoscope, but the physiological depth cues result ...

Pocket Stereoscope
A pocket is a bag- or envelope-like receptacle either fastened to or inserted in an article of clothing to hold small items. Pockets are also attached to luggage, backpacks, and similar items. In older usage, a pocket was a separate small bag or pouch. Origins Ancient people used leather or cloth pouches to hold valuables. Ötzi (also called the "Iceman"), who lived around 3,300 BCE, had a belt with a pouch sewn to it that contained a cache of useful items: a scraper, drill, flint flake, bone awl, and a dried tinder fungus. In European clothing, fitchets, resembling modern day pockets, appeared in the 13th century. Vertical slits were cut in the super tunic, which did not have any side openings, to allow access to purse or keys slung from the girdle of the tunic. According to historian Rebecca Unsworth, it was in the late 15th century that pockets became more noticeable. During the 16th century, pockets increased in popularity and prevalence. In slightly later European cloth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Brewster
Sir David Brewster KH PRSE FRS FSA Scot FSSA MICE (11 December 178110 February 1868) was a British scientist, inventor, author, and academic administrator. In science he is principally remembered for his experimental work in physical optics, mostly concerned with the study of the polarization of light and including the discovery of Brewster's angle. He studied the birefringence of crystals under compression and discovered photoelasticity, thereby creating the field of optical mineralogy.A. D. Morrison-Low (2004) "Brewster, Sir David (1781–1868)" in ''Oxford Dictionary of National Biography'' For this work, William Whewell dubbed him the "father of modern experimental optics" and "the Johannes Kepler of optics." A pioneer in photography, Brewster invented an improved stereoscope, which he called "lenticular stereoscope" and which became the first portable 3D-viewing device. He also invented the stereoscopic camera, two types of polarimeters, the polyzonal lens, the li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jules Richard (photographer)
Jules Richard (19 December 1848 - 18 June 1930) was a French photographer, businessman and instrument maker. Trained in part by his father, an instrument maker, Richard took over the family's business on his father's death. Richard was the inventor and manufacturer of the Verascope and Glyphoscope stereographic cameras, and also the Taxiphote stereographic viewer. Early career Richard's father Félix Richard was an instrument maker in Paris; his uncle was the electrical instrument maker Paul-Gustave Froment. After training in the his father's workshop, he worked outside the family company in the 1870s, manufacturing telegraphy equipment. Following his father's death in 1876, he returned to the family business in 1877, working in partnership with his younger brother Max starting in 1882. During the 1880s they built a reputation for manufacturing scientific barometers, and other environmental recording devices such as anemometers, pyrometers, aneroid barographs and dynamometers. ...

Antoine Claudet
Ada Byron's daguerreotype by Claudet, . Antoine François Jean Claudet (August 18, 1797 – December 27, 1867) was a French photographer and artist active in London who produced daguerreotypes. Early Years Claudet was born in La Croix-Rousse, France, the son of Claude Claudet, a cloth merchant and Etiennette Julie Montagnat. Career Early in his career Claudet headed a glass factory at Choisy-le-Roi, Paris, together with Georges Bontemps, and moved to England to promote the factory with a shop in High Holborn, London. Having acquired a share in L. J. M. Daguerre's invention, he became one of England's first commercial photographers using the daguerreotype process for portraiture, improving the sensitizing process by using chlorine (instead of bromine) in addition to iodine, thus gaining greater rapidity of action. He invented the red darkroom safelight, and it was he who suggested the idea of using a series of photographs to create the illusion of movement. The idea of us ...

Oliver Wendell Holmes, Sr
Oliver Wendell Holmes Sr. (; August 29, 1809 – October 7, 1894) was an American physician, poet, and polymath based in Boston. Grouped among the fireside poets, he was acclaimed by his peers as one of the best writers of the day. His most famous prose works are the "Breakfast-Table" series, which began with '' The Autocrat of the Breakfast-Table'' (1858). He was also an important medical reformer. In addition to his work as an author and poet, Holmes also served as a physician, professor, lecturer, inventor, and, although he never practiced it, he received formal training in law. Born in Cambridge, Massachusetts, Holmes was educated at Phillips Academy and Harvard College. After graduating from Harvard in 1829, he briefly studied law before turning to the medical profession. He began writing poetry at an early age; one of his most famous works, " Old Ironsides", was published in 1830 and was influential in the eventual preservation of the USS ''Constitution''.

Stereopticon
A stereopticon is a slide projector or relatively powerful "magic lantern", which has two lenses, usually one above the other, and has mainly been used to project photographic images. These devices date back to the mid 19th century, and were a popular form of entertainment and education before the advent of moving pictures. Magic lanterns originally used rather weak light sources, like candles or oil lamps, that produced projections that were just large and strong enough to entertain small groups of people. During the 19th century stronger light sources, like limelight, became available. For the "dissolving views" lantern shows that were popularized by Henry Langdon Childe since the late 1830s, lanternists needed to be able to project two aligned pictures in the same spot on a screen, gradually dimming a first picture while revealing a second one. This could be done with two lanterns, but soon biunial lanterns (with two objectives placed one above the other) became common. Wi ...

Daguerreotype
Daguerreotype (; french: daguerréotype) was the first publicly available photographic process; it was widely used during the 1840s and 1850s. "Daguerreotype" also refers to an image created through this process. Invented by Louis Daguerre and introduced worldwide in 1839, the daguerreotype was almost completely superseded by 1860 with new, less expensive processes, such as ambrotype ( collodion process), that yield more readily viewable images. There has been a revival of the daguerreotype since the late 20th century by a small number of photographers interested in making artistic use of early photographic processes. To make the image, a daguerreotypist polished a sheet of silver-plated copper to a mirror finish; treated it with fumes that made its surface light-sensitive; exposed it in a camera for as long as was judged to be necessary, which could be as little as a few seconds for brightly sunlit subjects or much longer with less intense lighting; made the resulting lat ...

Jules Duboscq
Louis Jules Duboscq (March 5, 1817 – September 24, 1886) was a French instrument maker, inventor, and pioneering photographer. He was known in his time, and is remembered today, for the high quality of his optical instruments. Life and work Duboscq was born at Seine-et-Oise in 1817. He was apprenticed in 1834 to Jean-Baptiste-François Soleil (1798–1878), a prominent instrument maker, and he married one of Soleil's daughters, Rosalie Jeanne Josephine, in 1839. Among the instruments Duboscq built were a stereoscope (marketing David Brewster's lenticular stereoscope), a colorimeter, a polarimeter, a heliostat and a saccharimeter.
