Cadmium Sulfide
Cadmium sulfide is the inorganic compound with the formula CdS. Cadmium sulfide is a yellow solid.Egon Wiberg, Arnold Frederick Holleman (2001''Inorganic Chemistry'' Elsevier It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite, but is more prevalent as an impurity substituent in the similarly structured zinc ores sphalerite and wurtzite, which are the major economic sources of cadmium. As a compound that is easy to isolate and purify, it is the principal source of cadmium for all commercial applications. Its vivid yellow color led to its adoption as a pigment for the yellow paint "cadmium yellow" in the 18th century. Production Cadmium sulfide can be prepared by the precipitation from soluble cadmium(II) salts with sulfide ion. This reaction has been used for gravimetric analysis and qualitative inorganic analysis.The preparative route and the subsequent treatment of the product, affects the polymorphic form that is produced ( ...

Charles Beseler Company
Charles Beseler Company is a Stroudsburg, Pennsylvania industrial company addressing four primary markets: public and corporate steel shelving and furniture, iron shelving and storage, shrink wrap packaging and silver halide photography ( film photography). The company now has two divisions left, its photo division and shrink wrap packaging. The company is a historic contributor to silver halide photography. The company still sells photographic enlargers; one of the few remaining companies to market the device. History The name Charles Beseler Company comes from Charles Beseler, a businessman in Germany in the 19th century who sold magic lanterns and stereopticons. Beseler died in 1909, but his company remained and then moved to New Jersey in 1919. The company manufactured photographic enlargers and other photographic equipment throughout the 20th century. It also imported the Topcon is a Japanese manufacturer of optical equipment for ophthalmology and surveying. History ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TTL Metering
In photography, through-the-lens metering (TTL metering) refers to a feature of cameras whereby the intensity of light reflected from the scene is measured through the lens; as opposed to using a separate metering window or external hand-held light meter. In some cameras various TTL metering modes can be selected. This information can then be used to set the optimal film or image sensor exposure ( average luminance), it can also be used to control the amount of light emitted by a flash unit connected to the camera. Description Through-the-lens metering is most often associated with single-lens reflex (SLR) cameras. In most film and digital SLRs, the light sensor(s) for exposure metering are incorporated into the pentaprism or pentamirror, the mechanism by which a SLR allows the viewfinder to see directly through the lens. As the mirror is flipped up, no light can reach there during exposure, the necessary amount of exposure needs to be determined before the actual exposure. Consequ ...

Miranda T (camera)
The original Miranda T 35mm SLR camera was launched by the newly established Japanese Orion Camera Co. in 1955. It is the first Japanese 35mm SLR camera to have an eyelevel Pentaprism finder. The camera was a success, and after only two years, the manufacturer changed its name to the Miranda Camera Co. The camera stayed in production for two more years while a series of new models designated model A, B, C, D, and S were introduced, based on the original camera. These comprised improvements like a faster shutter with 1/1000-second top speed, a frame counter, wind-on lever, and an Instant return mirror on model B in 1958. In addition, a rare Miranda TII with 1/1000-second top shutter speed does exist. The Miranda cameras were equipped with a double lensmount consisting of a wide 44mm internal thread and an external bayonet—the Pentax/Praktica screw mount is 42mm. The flange to film plane distance was deliberately made as short as possible to accommodate as many different makes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dresden
Dresden (, ; Upper Saxon: ''Dräsdn''; wen, label=Upper Sorbian, Drježdźany) is the capital city of the German state of Saxony and its second most populous city, after Leipzig. It is the 12th most populous city of Germany, the fourth largest by area (after Berlin, Hamburg and Cologne), and the third most populous city in the area of former East Germany, after Berlin and Leipzig. Dresden's urban area comprises the towns of Freital, Pirna, Radebeul, Meissen, Coswig, Radeberg and Heidenau and has around 790,000 inhabitants. The Dresden metropolitan area has approximately 1.34 million inhabitants. Dresden is the second largest city on the River Elbe after Hamburg. Most of the city's population lives in the Elbe Valley, but a large, albeit very sparsely populated area of the city east of the Elbe lies in the West Lusatian Hill Country and Uplands (the westernmost part of the Sudetes) and thus in Lusatia. Many boroughs west of the Elbe lie in the foreland of the Ore Mounta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ihagee
Ihagee was a camera manufacturer based in Dresden, Germany. Its best-known product was the Exakta single-lens reflex camera. History Johan Steenbergen, a Dutchman, founded a camera company called ''Industrie- und Handelsgesellschaft'' in Dresden in 1912. The name was shortened to Ihagee (based on the German pronunciation of the acronym IHG, ee-hah-geh). In 1918 six woodworkers joined Steenbergen at what was known from then on as, Ihagee Kamerawerk Steenbergen & Co. Ihagee's most successful camera by far was the Exakta, which was produced between 1933 and 1976. The series began in 1933 with the Standard, or VP, Exakta, which used 127 rollfilm. This was followed in 1936 by the popular 35mm Kine Exakta. Ihagee also made a smaller, less complex, version of the Exakta called the Exa. The company was greatly affected by World War II. Steenbergen left Dresden in 1942, never to return, and the Ihagee factory was destroyed during the Allied bombing of Dresden in February 1945. The par ...

Exakta
The Exakta (sometimes Exacta) was a camera produced by the ''Ihagee Kamerawerk'' in Dresden, Germany, founded as the Industrie und Handels-Gesellschaft mbH, in 1912. The inspiration and design of both the VP Exakta and the Kine Exakta are the work of the Ihagee engineer Karl Nüchterlein (see Richard Hummel's Spiegelreflexkameras aus Dresden), who did not survive the Second World War. An Exakta VX was used by James Stewart's character, a professional photographer, to spy on his possibly murderous neighbor in Alfred Hitchcock's ''Rear Window''. Characteristics Highlights of Exakta cameras include: * First single-lens reflex camera (SLR) for 127 roll film (VP Exakta) came in 1933 * First wind-on lever in 1934 * First built-in flash socket, activated by the shutter, in 1935 * First SLR for 35mm film came in 1936, the Kine Exakta Early Kine Exaktas had a fixed waist-level viewfinder, but later models, starting with the Exakta Varex, had an interchangeable waist- or eye-level fin ...

Canon Canonflex
The Canonflex is a Canon 35 mm film single-lens reflex (SLR) camera introduced in May 1959. Its standard lens is the ''Canon Camera Co. Super-Canomatic R 50mm lens 1.8''. The camera was in production for one year before it was replaced by the Canonflex R2000, adding a 1/2000 sec. shutter speed. History By the 1950s, the Japanese camera industry had turned their interest towards the 35 mm SLR camera, which to that point had been exclusively manufactured in Europe, and in particular in Dresden, Germany. The first Japanese 35 mm SLR camera was Asahiflex. It was soon followed by several manufacturers. The Miranda T was launched in 1955. In 1958 Minolta and Topcon followed, while Nikon presented their Nikon F in 1959, by that time a supplier of rangefinder cameras based on the Contax concept. Canon had established itself as a 35 mm rangefinder camera manufacturer, featuring a wide variety of camera models and lenses using the Leica 39mm standard lens mount. The fir ...

Nikon F
The Nikon F camera, introduced in April 1959, was Nikon's first SLR camera. It was one of the most advanced cameras of its day. Although many of the concepts had already been introduced elsewhere, it was revolutionary in that it was the first to combine them all in one camera. It was produced until October 1973 and was replaced by the Nikon F2. Aspects of its design remain in all of Nikon's subsequent SLR cameras, through the current Nikon F6 film and Nikon D6 digital models (which still share its Nikon F-mount for lenses). The "F" in Nikon F was selected from the term "re-f-lex", since the pronunciation of the first letter "R" is not available in many Asian languages. That tradition was carried all the way through their top line of Nikon cameras until the introduction of the Nikon D1 (digital) cameras decades later. Specially modified Nikon F cameras were used in space in the early 1970s aboard the Skylab space station. History The Nikon F was the first 35 mm SLR system ...

Reflex Finder
A reflex finder is a viewfinder system with a mirror placed behind a lens. The light passing through the lens is reflected by the mirror to a focusing screen, usually ground glass. The image formed on this ground glass can be observed directly, giving a ''waist-level reflex finder,'' or through a redressing optical device (set of mirrors or prism) for eye-level viewing, giving an ''eye-level reflex finder''. With a reflex finder, you can focus the image on the ground glass and frame your picture at the same time. It is common to find a device on the center of the ground glass to help precise focusing, for example a split-image or a microprism device. Today's reflex cameras usually incorporate autofocusing. Reflex finders are found in: * Single-lens reflex (SLR) cameras, with one lens for both viewing and taking the picture * Twin-lens reflex A twin-lens reflex camera (TLR) is a type of camera with two objective lenses of the same focal length. One of the lenses is the photo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
