Graphoscope
A graphoscope was a 19th-century device used in parlors in order to enhance the viewing of photographs A photograph (also known as a photo, image, or picture) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are now created ... and text. The graphoscope is supposed to be based on a 1864 patent of Charles John Rowsell. These novelty items consisted of a single magnifying glass, often in a wooden frame, in an overall construction that could collapse into a compact rectangular form. A photo/card holder was usually also included. A KOMBI camera often had included its design a graphoscope for better film viewing. Many devices combined a Stereoscope and Graphoscope.

Magnifying Glass
A magnifying glass is a convex lens that is used to produce a magnified image of an object. The lens is usually mounted in a frame with a handle. A magnifying glass can be used to focus light, such as to concentrate the sun's radiation to create a hot spot at the focus for fire starting. A sheet magnifier consists of many very narrow concentric ring-shaped lenses, such that the combination acts as a single lens but is much thinner. This arrangement is known as a Fresnel lens. The magnifying glass is an icon of detective fiction, particularly that of Sherlock Holmes. History "The evidence indicates that the use of lenses was widespread throughout the Middle East and the Mediterranean basin over several millennia". The earliest explicit written evidence of a magnifying device is a joke in Aristophanes's ''The Clouds'' from 424 BC, where magnifying lenses to ignite tinder were sold in a pharmacy, and Pliny the Elder's "lens", a glass globe filled with water, used to cauteri ...

Parlor
A parlour (or parlor) is a reception room or public space. In medieval Christian Europe, the "outer parlour" was the room where the monks or nuns conducted business with those outside the monastery and the "inner parlour" was used for necessary conversation between resident members. In the English-speaking world of the 18th and 19th century, having a parlour room was evidence of social status. Etymology In the early 13th century, parlor originally referred to a room where monks could go to talk, derived from the Old French word ''parloir'' or ''parler'' ("to speak"), it entered the English language around the turn of the 16th century. History The first known use of the word to denote a room was in medieval Christian Europe, when it designated the two rooms in a monastery where clergy, constrained by vow or regulation from speaking otherwise in the cloister, were allowed to converse without disturbing their fellows. The "outer parlour" was the room where the monks or nuns c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photographs
A photograph (also known as a photo, image, or picture) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are now created using a smartphone/camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating such images is called photography. Etymology The word ''photograph'' was coined in 1839 by Sir John Herschel and is based on the Greek φῶς (''phos''), meaning "light," and γραφή (''graphê''), meaning "drawing, writing," together meaning "drawing with light." History The first permanent photograph, a contact-exposed copy of an engraving, was made in 1822 using the bitumen-based "heliography" process developed by Nicéphore Niépce. The first photographs of a real-world scene, made using a camera obscura, followed a few years later at Le Gras, Fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zograscope
A zograscope is an optical device for magnifying flat pictures that also has the property of enhancing the sense of the depth shown in the picture. It consists of a large magnifying lens through which the picture is viewed. Devices containing only the lens are sometimes referred to as graphoscopes. Other models have the lens mounted on a stand in front of an angled mirror. This allows someone to sit at a table and to look through the lens at the picture flat on the table. Pictures viewed in this way need to be left-right reversed; this is obvious in the case of writing. A print made for this purpose, typically with extensive graphical projection perspective, is called a ''vue d'optique'' or "perspective view". Zograscopes were popular during the later half of the 18th century as parlour entertainments. Most existing ones from that time are fine furniture, with turned stands, mouldings, brass fittings, and fine finishes. According to Michael Quinion, the origin of the term is l ...
