Hexar RF
The Konica Hexar RF is a 35 mm rangefinder camera which was sold by Konica. It was introduced to the market on 13 October 1999. and subsequently discontinued (apparently without official notice) some time before the end of 2003. The camera used the "Bayonet Konica KM-mount", a copy of the Leica M-mount, thus sharing interchangeable lenses with those designed for Leica cameras and others compatible with them. The Hexar RF has a combined rangefinder/viewfinder modeled on that of Leica cameras, a similar body shape and size - and so is similar to Leica M-mount cameras in many aspects of operation. Lens mount The Konica Hexar RF accepts lenses designed for the "Bayonet Konica KM-mount" a copy of the Leica M-mount. Because of this, the Hexar RF can mount and focus lenses designed for the Leica and other compatible M-mount cameras or, when used with an adapter, the earlier Leica thread mount lenses (note that due to physical constraints there is no adapter to allow bayonet mount len ...

135 Film
135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film used for still photography. It is a film with a film gauge of loaded into a standardized type of magazine – also referred to as a cassette or cartridge – for use in 135 film cameras. The engineering standard for this film is controlled by ISO 1007 titled '135-size film and magazine'. The term 135 was introduced by Kodak in 1934 as a designation for 35 mm film specifically for still photography, perforated with Kodak Standard perforations. It quickly grew in popularity, surpassing 120 film by the late 1960s to become the most popular photographic film size. Despite competition from formats such as 828, 126, 110, and APS, it remains the most popular film size today. The size of the 135 film frame with its aspect ratio of 1:1.50 has been adopted by many high-end digital single-lens reflex and digital mirrorless cameras, commonly referred to as " full frame".

Composition (visual Arts)
The term composition means "putting together". It can be thought of as the organization of the elements of art according to the principles of art. Composition can apply to any work of art, from music through writing and into photography, that is arranged using conscious thought. In the visual arts, composition is often used interchangeably with various terms such as ''design, form, visual ordering,'' or ''formal structure,'' depending on the context. In graphic design for press and desktop publishing, composition is commonly referred to as page layout. The composition of a picture is different from its subject (what is depicted), whether a moment from a story, a person or a place. Many subjects, for example Saint George and the Dragon, are often portrayed in art, but using a great range of compositions even though the two figures are typically the only ones shown. Elements of design The central visual element, known as ''element of design'', ''formal element'', or ''elemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DX Encoding
DX (Digital indeX) encoding is an ANSI and I3A standard, originally introduced by Kodak in March 1983, for marking 135 and APS photographic film and film cartridges. It consists of several parts, a latent image DX film edge barcode on the film below the sprocket holes, a code on the cartridge used by automatic cameras, and a barcode on the cartridge read by photo-finishing machines. History In order to simplify the handling of 35 mm film in 135 format Kodak introduced the DX encoding method on 3 January 1983. In contrast to former solutions like Fuji's film speed encoding method in 1977, which was already using electrical contacts for film speed detection on 135 format cartridges, Kodak's later DX code system immediately met success in the marketplace. The first DX encoded film was the color negative film Kodacolor VR-1000 in March 1983. The first cameras to use the technology was the Konica TC-X SLR (1985), [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photographic Film
Photographic film is a strip or sheet of transparent film base coated on one side with a gelatin photographic emulsion, emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast, and image resolution, resolution of the film. The emulsion will gradually darken if left exposed to light, but the process is too slow and incomplete to be of any practical use. Instead, a very short exposure (photography), exposure to the image formed by a camera lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent image in the emulsion, which can be chemically photographic processing, developed into a visible photograph. In addition to visible light, all films are sensitive to ultraviolet light, X-rays, gamma rays, and particle radiation, high-energy particles. Unmodified silver halide crys ...

Konica Hexar
The Konica Hexar is a 35 mm fixed-lens, fixed focal length autofocus camera which was produced through the 1990s. It was introduced to the market in 1993. While styled like a rangefinder camera, and intended for a similar style of photography, in specification it is more like a larger "point and shoot" camera. The Konica Hexar enjoys something of a "cult status" among film camera aficionados because of the quality of its lens, rangefinder-style ergonomics and interesting and useful operating modes (notably its "silent mode"). Lens The camera is fitted with a 35mm fixed- focal length lens with autofocus and with a large maximum aperture of f2. The lens accepts lens filters of 46mm diameter (however, camera settings must be manually adjusted to compensate for any reduction in light transmission caused by the filter). A metal pull-out lens hood surrounds the lens. The lens on the Hexar is considered to be of high quality for this type of camera and is often compared with oth ...

Contax G2
The Contax G camera line consists of two cameras, the G1 and G2, interchangeable-lens cameras sold by Kyocera under the Contax brand in competition with the Leica M7, Cosina Voigtländer Bessa-R, and Konica Hexar RF. The G1 was introduced in 1994 with the G2 joining it in 1996. In 2005, Kyocera retreated from the camera business and announced it would cease all activity related to the manufacture of Contax cameras at the end of the year, effectively spelling the end of the G system. Design The two G-series cameras have titanium-clad bodies and use the Contax G-mount, an electronic autofocus mount. When tested in 1995, the Contax G1 cost with the 45 mm Planar lens; the 28 mm Biogon and 90 mm Sonnar lenses were each , and the list price for the 16 mm Hologon was . The 45 mm Planar was listed separately at . The Contax G2 listed for with the 45 mm Planar lens in 1999. Critics were quick to accuse the G1 of not being a "true" (mechanical) rangefinder, ...

Titanium
Titanium is a chemical element with the symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll and Hunter processes. The most common compound, titanium dioxide, is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and catalysts; and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Battery (electricity)
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell. Primary (single-use or "disposable") batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery used ...

Leica M3
The Leica M3 is a 35 mm rangefinder camera by Ernst Leitz GmbH (now Leica Camera AG), introduced in 1954. It was a new starting point for Leitz, which until then had only produced screw-mount Leica cameras that were incremental improvements to its original Leica (Ur-Leica). The M3 introduced several features to the Leica, among them the combination of viewfinder and rangefinder in one bright window, like on the Contax II, a bayonet lens mount, and rapid film advance lever. It was the most successful model of the M series, with over 220,000 units sold by the time production of the M3 model ended in 1966. It was succeeded by a number of later film M series cameras, including the Leica M-A film camera in 2014. The earliest Leica M3 pre-model that was built, sold at auction in 2009 for €72,000. In June 2019 a pre series model from 1952/1953 was sold for €360.000 at the 34th Leitz auction in Wetzlar. Mount This new bayonet mount, which has not been changed in the following hal ...

Camera
A camera is an Optics, optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a Image sensor, digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A Shutter (photography), shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera dom ...
