Occupation Of Japan
Japan was occupied and administered by the victorious Allies of World War II from the 1945 surrender of the Empire of Japan at the end of the war until the Treaty of San Francisco took effect in 1952. The occupation, led by the United States with support from the British Commonwealth and under the supervision of the Far Eastern Commission, involved a total of nearly 1 million Allied soldiers. The occupation was overseen by American General Douglas MacArthur, who was appointed Supreme Commander for the Allied Powers by US President Harry Truman; MacArthur was succeeded as supreme commander by General Matthew Ridgway in 1951. Unlike in the occupation of Germany, the Soviet Union had little to no influence over the occupation of Japan, declining to participate because it did not want to place Soviet troops under MacArthur's direct command. This foreign presence marks the only time in Japan's history that it has been occupied by a foreign power. However, unlike in Germany t ...

Mycro Film
''Micro'' (Greek letter μ ( U+03BC) or the legacy symbol µ (U+00B5)) is a unit prefix in the metric system denoting a factor of 10−6 (one millionth). Confirmed in 1960, the prefix comes from the Greek ('), meaning "small". The symbol for the prefix is the Greek letter μ ( mu). It is the only SI prefix which uses a character not from the Latin alphabet. "mc" is commonly used as a prefix when the character "μ" is not available; for example, "mcg" commonly denotes a microgram. This may be ambiguous in rare circumstances in that ''mcg'' could also be read as a ''micrigram'', i.e. 10−14 g; however the prefix '' micri'' is not standard, nor widely known, and is considered obsolete. The letter u, instead of μ, was allowed by an ISO document, but that document has been withdrawn in 2001, however DIN 66030:2002 still allows this substitution. Examples * Typical bacteria are 1 to 10 micrometres (1–10 µm) in diameter. * Eukaryotic cells are typically 10 to 100 micrometre ...

Fixed-focus Lens
A photographic lens for which the focus is not adjustable is called a fixed-focus lens or sometimes focus-free. The focus is set at the time of lens design, and remains fixed. It is usually set to the hyperfocal distance, so that the depth of field ranges all the way down from half that distance to infinity, which is acceptable for most cameras used for capturing images of humans or objects larger than a meter. Rather than having a method of determining the correct focusing distance and setting the lens to that focal point, a fixed-focus lens relies on sufficient depth of field to produce acceptably sharp images. Most cameras with focus-free lenses also have a relatively small aperture, which increases the depth of field. Fixed-focus cameras with extended depth of field (EDOF) sometimes are known as full-focus cameras. Concept In order to reach a minimal focal distance, the aperture and the focal length of the lens are reduced (a slow wide-angle lens), to make the hyperfocal ...

Popular Photography
''Popular Photography'', formerly known as ''Popular Photography & Imaging'', also called ''Pop Photo'', is a monthly American consumer website and former magazine that at one time had the largest circulation of any imaging magazine, with an editorial staff twice the size of its nearest competitor. Although the magazine ceased publication in early 2017, PopPhoto had a soft relaunch as a web-only publication the following year, and an official relaunch in December 2021. History The first issue of ''Popular Photography'' was published in 1937. It was based in New York City and owned by a number of companies during its lifetime, including Ziff Davis. It was sold by Hachette Filipacchi Media U.S. to Bonnier Corporation in 2009. The magazine's last publisher was Steven B. Grune and its last editor-in-chief was Miriam Leuchter. One of its most well-known editors was American photographer and writer Norman Rothschild, whom Edward Steichen Edward Jean Steichen (March 27, 1879 – Mar ...

Viewfinder
In photography, a viewfinder is what the photographer looks through to compose, and, in many cases, to focus the picture. Most viewfinders are separate, and suffer parallax, while the single-lens reflex camera lets the viewfinder use the main optical system. Viewfinders are used in many cameras of different types: still and movie, film, analog and digital. A zoom camera usually zooms its finder in sync with its lens, one exception being rangefinder cameras. History Before the development of microelectronics and electronic display devices, only optical viewfinders existed. Direct optical viewfinders Direct viewfinders are essentially miniature Galilean telescopes; the viewer's eye was placed at the back, and the scene viewed through the viewfinder optics. A declining minority of point and shoot cameras use them. Parallax error results from the viewfinder being offset from the lens axis, to point above and usually to one side of the lens. The error varies with distance, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulb (photography)
The Bulb setting (abbreviated B) on camera shutters is a momentary-action mode that holds shutters open for as long as a photographer depresses the shutter-release button. The Bulb setting is distinct from shutter's Time (T) setting, which is an alternate-action mode where the shutter opens when the shutter-release button is pressed and released once, and closes when the button is actuated again. History Decades before the first flashbulbs, some box cameras and many view cameras and folding cameras came with a detachable pneumatic shutter release with a rubber bulb on the end; "Bulb" refers to the rubber shutter release bulb. Though mechanically timed exposures could also be triggered by squeezing the shutter release bulb, "Bulb" exposures then had the same momentary action as camera shutters have today, as per this description from Sears Roebuck's 1909 ''Cameras Photographic Supplies'': Around 1894 in Germany, the momentary-action setting on camera shutters made by C. A. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roll Film
Roll film or rollfilm is any type of spool-wound photographic film protected from white light exposure by a paper backing. The term originated in contrast to sheet film. Confusingly, roll film was originally often referred to as "cartridge" film because of its resemblance to a shotgun cartridge. The opaque backing paper allows roll film to be loaded in daylight. It is typically printed with frame number markings which can be viewed through a small red window at the rear of the camera. A spool of roll film is usually loaded on one side of the camera and pulled across to an identical take up spool on the other side of the shutter as exposures are made. When the roll is fully exposed, the take up spool is removed for processing and the empty spool on which the film was originally wound is moved to the other side, becoming the take up spool for the next roll of film. History In 1881 a farmer in Cambria, Wisconsin, Peter Houston, invented the first roll film camera. His younger br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photography In Japan
The history of photography in Japan begins in the 19th century and has continued to be a prominent art form into the present era. 19th-century Importation of photography In 1848 (Edo era), a camera for daguerréotype was imported by a Dutch ship to Japan (Nagasaki, 長崎). It is said that this was the first camera in Japan. During Edo era, the import and the export had been prohibited (''sakoku'', 鎖国) by the Edo Government (''Edobakufu'', 江戸幕府), except that only Dutch ships had been permitted to export and import various goods at Nagasaki Port. Therefore, the first camera was introduced at Nagasaki. This camera was imported by Ueno Toshinojō (1790–1851, 上野俊之丞) and in 1849 passed to Shimazu Nariakira (1809–1858, 島津斉彬), who later would become a feudal lord (''daimyō,'' 大名) of Satsuma Domain (薩摩藩, now ''Kagoshima-ken''). In Satsuma Domain, detailed study with respect to photography had been done, but it took almost ten years from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
