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 resul ...

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] |

Antoine François Jean Claudet (August 18, 1797 – December 27, 1867) was a French Photography, 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 Louis Daguerre, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, and inventor. 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''. Following training at the prestigious medical schools of Paris, Holmes was grante ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. W ...

Daguerreotype
Daguerreotype was the first publicly available photography, photographic process, 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 1856 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 Plating#Silver plating, silver-plated copper to a mirror finish; treated it with fumes that made its surface light-sensitive; exposure (photography), exposed it in a camera obscura, 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 ...

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 Villaines-sous-Bois (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 A heliostat () is a device that reflects sunlight toward a target, turning to compensate for the Sun's apparent motion. The reflector is usually a plane mirror. The target may be a physical object, distant from the heliostat, or a direct ... and a saccharimeter.

Great Exhibition
The Great Exhibition of the Works of Industry of All Nations, also known as the Great Exhibition or the Crystal Palace Exhibition (in reference to the temporary structure in which it was held), was an international exhibition that took place in Hyde Park, London, from 1 May to 15 October 1851. It was the first in a series of world's fairs, exhibitions of culture and industry that became popular in the 19th century. The event was organised by Henry Cole and Prince Albert, husband of Victoria, Queen of the United Kingdom. Famous people of the time attended the Great Exhibition, including Charles Darwin, Karl Marx, Michael Faraday (who assisted with the planning and judging of exhibits), Samuel Colt, members of the Orléanist royal family and the writers Charlotte Brontë, Charles Dickens, Lewis Carroll, George Eliot, Alfred Tennyson, and William Makepeace Thackeray. The future Arts and Crafts proponent William Morris, then a teenager, later said he refused to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lens (optics)
A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (''elements''), usually arranged along a common axis. Lenses are made from materials such as glass or plastic and are ground, polished, or molded to the required shape. A lens can focus light to form an image, unlike a prism, which refracts light without focusing. Devices that similarly focus or disperse waves and radiation other than visible light are also called "lenses", such as microwave lenses, electron lenses, acoustic lenses, or explosive lenses. Lenses are used in various imaging devices such as telescopes, binoculars, and cameras. They are also used as visual aids in glasses to correct defects of vision such as myopia and hypermetropia. History The word ''lens'' comes from , the Latin name of the lentil (a seed of a lentil pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
