Warsaw Photo-Optical Works
Warsaw Photo-Optical Works (Polish: Warszawskie Zakłady Fotooptyczne or WZFO) was a Polish firm that built optical and photographic equipment. The company was initially founded in 1951 as the Warsaw Cine-Technical Works at the direction of Prime Minister Bolesław Bierut. Oversight of the company was given to the Central Cinematography Committee of Poland, which passed the company to the Heavy Industry Ministry in 1952. The company's name was then changed to the Warsaw Photo-Optical Works, and they began to focus exclusively on producing cameras and related equipment. The WZFO was the first company to mass-produce photographic equipment in Poland, beginning with the Start camera in 1953-1954. Between 1954-1957, WZFO introduced the Fenix, a relatively higher-end viewfinder camera, and the Druh, a simple Bakelite-cased camera popular with young people. When the Druh series ceased production around 1958, the Ami series was introduced as its replacement. In 1962, the firm released t ...

Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that can ...

Technology Companies Disestablished In 1968
Technology is the application of knowledge to reach practical goals in a specifiable and reproducible way. The word ''technology'' may also mean the product of such an endeavor. The use of technology is widely prevalent in medicine, science, industry, communication, transportation, and daily life. Technologies include physical objects like utensils or machines and intangible tools such as software. Many technological advancements have led to societal changes. The earliest known technology is the stone tool, used in the prehistoric era, followed by fire use, which contributed to the growth of the human brain and the development of language in the Ice Age. The invention of the wheel in the Bronze Age enabled wider travel and the creation of more complex machines. Recent technological developments, including the printing press, the telephone, and the Internet have lowered communication barriers and ushered in the knowledge economy. While technology contributes to economic deve ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Photography
Photography is the visual art, art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and Mass communication, mass communication. Typically, a Lens (optics), lens is used to focus (optics), focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed Exposure (photography), exposure. With an electronic image sensor, this produces an Charge-coupled device, electrical charge at each pixel, which is Image processing, electronically processed and stored in a Image file formats, digital image file for subsequent display or processing. The result with photographic emulsion is ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ami (camera)
The Ami is a viewfinder camera made of plastic, produced during the communist era of Poland era by the Polish firm Warsaw Photo-Optical Works or WZFO. It was the successor to their Bakelite-cased Druh camera, which was popular with youth due to its simplicity. The Ami was also quite popular, although its availability was sometimes restricted due to production limits in the economy imposed by the government. The word ''ami'' does not have any particular meaning in Polish, but French was a widely known language in Poland at the time and it is thus possible that the name refers to the French word ''ami'' ("friend"). Models Three models of the Ami were released: the original Ami, the Ami 2, and the Ami 66. All three had bodies made from styropol, a high-impact polystyrene Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed.
