C. Cameron Macauley
Charles Cameron Macauley (October 20, 1923 – May 17, 2007) was a photographer, filmmaker and educator noted for his prize winning still photographs, his ethnographic films and his expertise on historic films and photographs. His career spanned over 75 years. Biography Early life Charles Cameron Macauley was born on October 20, 1923, in Grand Rapids, Michigan. He was the younger brother of the noted editor and novelist Robie Macauley. Both boys took an interest in photography, and at the age of ten Macauley purchased his first Norton camera, a prototype of the highly successful Univex Model A, which sold for 39 cents and was among the first inexpensive cameras marketed for the general public. Macauley also experimented with a folding Kodak Bantam camera, a Foth Derby, a Rolleicord, Rolleicord I, an Argus, a National Graflex and a Miniature Speed Graphic with a soft focus Verito lens. By the late 1930s Macauley began doing commercial photography using a 4x5 Speed Graphic. He was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petty Officer
A petty officer (PO) is a non-commissioned officer in many navies and is given the NATO rank denotation OR-5 or OR-6. In many nations, they are typically equal to a sergeant in comparison to other military branches. Often they may be superior to a seaman, and subordinate to more senior non-commissioned officers, such as a chief petty officers. Petty officers are usually sailors that have served at least several years in their respective navies. Petty officers represent the junior and mid-grade non-commissioned officer ranks of many naval services, and are generally responsible for the day-to-day supervision of ranks junior to them. They may also serve as technical specialists within their rating (military occupation). Origin The modern petty officer dates back to the Age of Sail in the Royal Navy. Petty officers rank between naval officers (both commissioned and warrant) and most enlisted sailors. These were men with some claim to officer rank, sufficient to distinguish t ...

Soft Focus
In photography, soft focus is a lens flaw, in which the lens forms images that are blurred due to spherical aberration. A soft focus lens deliberately introduces spherical aberration in order to give the appearance of blurring the image while retaining sharp edges; it is not the same as an out-of-focus image, and the effect cannot be achieved simply by defocusing a sharp lens. Soft focus is also the name of the style of photograph produced by such a lens. Photography Because soft focus results from what are considered technical flaws, typically spherical and chromatic aberration, many older lenses had soft focus built in as a side effect of their construction. Some lens makers, such as Pinkham-Smith and Busch Nicola Perscheid (see Nicola Perscheid), intentionally designed lenses to take advantage of these flaws and, as color became available, chromatic aberration was less desirable, but well-managed spherical aberration was desirable. Newer lenses are optimized to minimize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photogrammetry
Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring and interpreting photographic images and patterns of electromagnetic radiant imagery and other phenomena. The term photogrammetry was coined by the Prussian architect Albrecht Meydenbauer, which appeared in his 1867 article "Die Photometrographie." There are many variants of photogrammetry. One example is the extraction of three-dimensional measurements from two-dimensional data (i.e. images); for example, the distance between two points that lie on a plane parallel to the photographic image plane can be determined by measuring their distance on the image, if the scale (map), scale of the image is known. Another is the extraction of accurate color ranges and values representing such quantities as albedo, specular reflection, Metallicity#Photometric colors, metallicity, or ambient occlusion from photographs of mater ...

Greenland
Greenland ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland is the world's largest island. It is one of three constituent countries that form the Kingdom of Denmark, along with Denmark and the Faroe Islands; the citizens of these countries are all citizens of Denmark and the European Union. Greenland's capital is Nuuk. Though a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers) for more than a millennium, beginning in 986.The Fate of Greenland's Vikings , by Dale Mackenzie Brown, ''Archaeological Institute of America'', ...

Photolithography
In integrated circuit manufacturing, photolithography or optical lithography is a general term used for techniques that use light to produce minutely patterned thin films of suitable materials over a substrate, such as a silicon wafer, to protect selected areas of it during subsequent etching, deposition, or implantation operations. Typically, ultraviolet light is used to transfer a geometric design from an optical mask to a light-sensitive chemical (photoresist) coated on the substrate. The photoresist either breaks down or hardens where it is exposed to light. The patterned film is then created by removing the softer parts of the coating with appropriate solvents. Conventional photoresists typically consists of three components: resin, sensitizer, and solvent. Photolithography processes can be classified according to the type of light used, such as ultraviolet, deep ultraviolet, extreme ultraviolet, or X-ray. The wavelength of light used determines the minimum feature si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alfred Stieglitz
Alfred Stieglitz (January 1, 1864 – July 13, 1946) was an American photographer and modern art promoter who was instrumental over his 50-year career in making photography an accepted art form. In addition to his photography, Stieglitz was known for the New York art galleries that he ran in the early part of the 20th century, where he introduced many avant-garde European artists to the U.S. He was married to painter Georgia O'Keeffe. Early life and education Stieglitz was born in Hoboken, New Jersey, the first son of German Jewish immigrants Edward Stieglitz (1833–1909) and Hedwig Ann Werner (1845–1922). His father was a lieutenant in the Union Army and worked as a wool merchant. He had five siblings, Flora (1865–1890), twins Julius (1867–1937) and Leopold (1867–1956), Agnes (1869–1952) and Selma (1871–1957). Alfred Stieglitz, seeing the close relationship of the twins, wished he had a soul mate of his own during his childhood. Stieglitz attended Charlier I ...
