Moonrise, Hernandez, New Mexico
''Moonrise, Hernandez, New Mexico'' is a black-and-white photograph taken by Ansel Adams, late in the afternoon on November 1, 1941, from a shoulder of highway US 84 / US 285 in the unincorporated community of Hernandez, New Mexico, United States. The photograph shows the Moon rising in a dominating black sky with low clouds above a collection of modest dwellings, a church and a cross-filled graveyard, with snow-covered mountains in the background. Adams captured a single image, with the sunset lighting the white crosses and buildings. Because Adams did not date the image, attempts have been made to determine a date from astronomical information in the photograph. It is one of Adams' most popular works. Creation In October 1941, United States Secretary of the Interior Harold Ickes hired Adams for six months to create photographs of lands under the jurisdiction of the Department of the Interior, for use as mural-sized prints for decoration of the department's ne ...

Color Graphics Adapter
The Color Graphics Adapter (CGA), originally also called the ''Color/Graphics Adapter'' or ''IBM Color/Graphics Monitor Adapter'', introduced in 1981, was IBM's first color graphics card for the IBM PC and established a De facto standard, de facto computer display standard. Hardware design The original IBM CGA graphics card was built around the Motorola 6845 display controller, came with 16 kilobytes of video memory built in, and featured several graphics and text modes. The highest display resolution of any mode was 640 × 200, and the highest color depth supported was 4-bit (16 colors). The CGA card could be connected either to a direct-drive CRT monitor using a 4-bit digital (Transistor-transistor logic, TTL) RGB(I), RGBI interface, such as the IBM 5153 color display, or to an NTSC-compatible television or composite video computer monitor, monitor via an RCA connector.

Dennis Di Cicco
Dennis di Cicco (born 1950) is an American amateur astronomer and a discoverer of minor planets, who lives in New England. He has discovered 60 numbered asteroids from his backyard observatory in Sudbury, Massachusetts (IAU code: IAU code#817, 817). He was a member of the editorial staff of ''Sky and Telescope'' magazine from 1974 until his resignation as senior editor in June 2014. His special interests include astronomical photography and the history of astronomical photography, telescope making, and astronomical observing. During 1978 and 1979 he was the first person to successfully photograph the analemma, making 48 separate exposures on a single piece of film during a 12-month period. The project is described in the June 1979 issue of ''Sky & Telescope''. The asteroid 3841 Dicicco was named after him. Di Cicco conducted observations and calculations to determine the exact time and date of Ansel Adams’ famous 1941 photograph, ''Moonrise, Hernandez, New Mexico''. He grew up ...

Beaumont Newhall (June 22, 1908 – February 26, 1993) was an American curator, art historian, writer, photographer, and the second director of the George Eastman Museum. His book, ''The History of Photography'', remains one of the most significant accounts in the field and has become a classic photographic history textbook.

Although Newhall wanted to study film and photography in college, the subjects were not taught as separate disciplines when he ...

Dark Slide (photography)
In photography, a dark slide is a wooden or metal plate that covers the sensitized emulsion side of a photographic plate. In use, a pair of plates joined back to back were used with both plates covered with a dark slide. When used, the dark slide is removed for the period of the exposure and then replaced. Modern dark slides are used in conjunction with a film holder, that either holds in place pieces of cut sheet film or, if modified, some piece of light sensitive material such as glass. In place, the dark slide is in a film holder or magazine. Film holders usually refer to cut sheet film and magazines refer to roll film. Vintage film holders were made of wood and held in place either photo-sensitized plates or photo sensitive film. In either case, the construction must be such to reduce light leaks, or any unwanted light from striking the film until the holder is held in place by a camera and considered "light tight". Some holders held only one piece of light sensitive materia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zone System
The Zone System is a photographic technique for determining optimal film exposure and development, formulated by Ansel Adams and Fred Archer. Adams described the Zone System as " ..not an invention of mine; it is a codification of the principles of sensitometry, worked out by Fred Archer and myself at the Art Center School in Los Angeles, around 1939–40." The technique is based on the late 19th-century sensitometry studies of Hurter and Driffield. The Zone System provides photographers with a systematic method of precisely defining the relationship between the way they visualize the photographic subject and the final results. Although it originated with black-and-white sheet film, the Zone System is also applicable to roll film, both black-and-white and color, negative and reversal, and to digital photography. Principles Visualization An expressive image involves the arrangement and rendering of various scene elements according to the photographer's desire. Achievin ...

Candela
The candela (symbol: cd) is the unit of luminous intensity in the International System of Units (SI). It measures luminous power per unit solid angle emitted by a light source in a particular direction. Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light in the source's spectrum, the contribution of each wavelength is weighted by the luminous efficiency function, the model of the sensitivity of the human eye to different wavelengths, standardized by the CIE and ISO. A common wax candle emits light with a luminous intensity of roughly one candela. If emission in some directions is blocked by an opaque barrier, the emission would still be approximately one candela in the directions that are not obscured. The word ''candela'' is Latin for ''candle''. The old name "candle" is still sometimes used, as in '' foot-candle'' and the modern definition of '' candlepower''. Definition The 26th General C ...
