Dodging And Burning
Dodging and burning are terms used in photography for a technique used during the printing process to manipulate the exposure of select areas on a photographic print, deviating from the rest of the image's exposure. In a darkroom print from a film negative, dodging decreases the exposure for areas of the print that the photographer wishes to be lighter, while burning increases the exposure to areas of the print that should be darker. Any material with varying degrees of opacity may be used, as preferred, to cover and/or obscure the desired area for burning or dodging. One may use a transparency with text, designs, patterns, a stencil, or a completely opaque material shaped according to the desired area of burning/dodging. Many modern digital image editing programs have "dodge" and "burn" tools that mimic the effect on digital images. Applications A key application of dodging and burning is to improve contrast (tonal reproduction) in film print-making; today this is better know ...

Darkroom
A darkroom is used to process photographic film, to make prints and to carry out other associated tasks. It is a room that can be made completely dark to allow the processing of the light-sensitive photographic materials, including film and photographic paper. Various equipment is used in the darkroom, including an enlarger, baths containing chemicals, and running water. Darkrooms have been used since the inception of photography in the early 19th century. Darkrooms have many various manifestations, from the elaborate space used by Ansel Adams to a retooled ambulance wagon used by Timothy H. O'Sullivan. From the initial development of the film to the creation of prints, the darkroom process allows complete control over the medium. Due to the popularity of color photography and complexity of processing color film (''see C-41 process'') and printing color photographs and also to the rise, first of instant photography technology and later digital photography, darkrooms are dec ...

Enlarger
An enlarger is a specialized transparency projector used to produce photographic prints from film or glass negatives, or from transparencies. Construction All enlargers consist of a light source, normally an incandescent light bulb shining though a condenser or translucent screen to provide even illumination, a holder for the negative or transparency, and a specialized lens for projection. The light passes through a film holder, which holds the exposed and developed photographic negative or transparency. Prints made with an enlarger are called ''enlargements''. Typically, enlargers are used in a darkroom, an enclosed space from which extraneous light may be excluded; some commercial enlargers have an integral dark box so that they can be used in a light-filled room. History Josef Maria Eder, in his ''History of Photography'' attributes the invention of photographic enlargement to Humphry Davy who realised the idea of using a solar microscope to project images onto sensitis ...

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. Achieving the ...

Ansel Adams
Ansel Easton Adams (February 20, 1902 – April 22, 1984) was an American landscape photographer and environmentalist known for his black-and-white images of the American West. He helped found Group f/64, an association of photographers advocating "pure" photography which favored sharp focus and the use of the full tonal range of a photograph. He and Fred Archer developed an exacting system of image-making called the Zone System, a method of achieving a desired final print through a deeply technical understanding of how tonal range is recorded and developed during exposure, negative development, and printing. The resulting clarity and depth of such images characterized his photography. Adams was a life-long advocate for environmental conservation, and his photographic practice was deeply entwined with this advocacy. At age 12, he was given his first camera during his first visit to Yosemite National Park. He developed his early photographic work as a member of the Sierra C ...

Albert Schweitzer
Ludwig Philipp Albert Schweitzer (; 14 January 1875 – 4 September 1965) was an Alsatian-German/French polymath. He was a theologian, organist, musicologist, writer, humanitarian, philosopher, and physician. A Lutheran minister, Schweitzer challenged both the secular view of Jesus as depicted by the historical-critical method current at this time, as well as the traditional Christian view. His contributions to the interpretation of Pauline Christianity concern the role of Paul's mysticism of "being in Christ" as primary and the doctrine of justification by faith as secondary. He received the 1952 Nobel Peace Prize for his philosophy of "Reverence for Life", becoming the eighth Frenchman to be awarded that prize. His philosophy was expressed in many ways, but most famously in founding and sustaining the Hôpital Albert Schweitzer in Lambaréné, French Equatorial Africa (now Gabon). As a music scholar and organist, he studied the music of German composer Johann Sebasti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photography
Photography is the 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. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purp ...

Photo Essay
A photographic essay or photo-essay for short is a form of visual storytelling, a way to present a narrative through a series of images. A photo essay delivers a story using a series of photographs and brings the viewer along a narrative journey. Examples of photo essays include: * A web page or portion of a web site. * A single montage or collage of photographic images, with text or other additions, intended to be viewed both as a whole and as individual photographs. Such a work may also fall in the category of mixed media. * An art show which is staged at a particular time and location. Some such shows may also fall into other categories. * In fashion publishing especially, a photo-editorial – an editorial-style article dominated by or entirely consisting of a series of thematic photographs. Photographers known for their photo-essays include: * W. Eugene Smith * Ansel Adams **Adams's ''Born Free and Equal'' (1944) documented Japanese Americans held at the Manzanar War ...
