Infrared Photography
In infrared photography, the photographic film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum; these filters thus look black (opaque) or deep red. When these filters are used together with infrared-sensitive film or sensors, " in-camera effects" can be obtained; false-color or black-and-white images with a dreamlike or sometimes lurid appearance known as the "Wood Effect," an effect mainly caused by foliage (such as tree leaves and grass) strongly reflecting infrared in the same way visible light is reflected from snow. There is a small contribution from c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree Example IR
In botany, a tree is a perennial plant with an elongated Plant stem, stem, or trunk (botany), trunk, usually supporting Branch, branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only Bark (botany), woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller Arecaceae, palms, Cyatheales, tree ferns, Musa (genus), bananas, and bamboos. Trees are not a Monophyletic group, monophyletic taxonomic group but consist of a wide variety of plant species that Convergent evolution, have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mie Scattering
In electromagnetism, the Mie solution to Maxwell's equations (also known as the Lorenz–Mie solution, the Lorenz–Mie–Debye solution or Mie scattering) describes the scattering of an electromagnetic plane wave by a homogeneous sphere. The solution takes the form of an infinite series of spherical multipole partial waves. It is named after German physicist Gustav Mie. The term ''Mie solution'' is also used for solutions of Maxwell's equations for scattering by stratified spheres or by infinite cylinders, or other geometries where one can write separate equations for the radial and angular dependence of solutions. The term ''Mie theory'' is sometimes used for this collection of solutions and methods; it does not refer to an independent physical theory or law. More broadly, the "Mie scattering" formulas are most useful in situations where the size of the scattering particles is comparable to the wavelength of the light, rather than much smaller or much larger. Mie scattering ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederick Wratten
Frederick Charles Luther Wratten (1840, England – 8 April 1926,Macmillan Biographical Encyclopedia of Photographic Artists & Innovators. By Turner Browne and Elaine Partnow. London: Collier Macmillan Publishers, . (MacBEP) London) was an English inventor. Wratten started his career as a school teacher and organist, and moved to London in 1861 to become a clerk at Joseph Solomon's Photographic & Optical Warehouse. His work at the warehouse stimulated his interest in photography, and while there he learned how to use gelatin in a sensitized emulsion and began experimenting on his own. In 1876, Wratten developed the use of alcohol in drying gelatin emulsion and removing unwanted silver nitrate. This process was described in the '' British Journal of Photography'' of 1877 and 1878. During the course of his experiments, Wratten formed a partnership with Henry Wainwright (1877~) for the manufacturing and sale of photographic supplies. ''Wratten & Wainwright'' were the first firm i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kenneth Mees
Charles Edward Kenneth Mees FRS (26 May 1882 – 15 August 1960) was a British scientist and photographic researcher. Early life and education Mees was born in Wellingborough, England, the son of a Wesleyan minister. He attended the University of London. In 1906 he was awarded his D.Sc. with a dissertation on photographic theory. Career From 1906 until 1912, Mees worked for Wratten and Wainwright, Ltd., assisting Frederick Wratten in developing the first panchromatic photographic plates, as well as light filters and safelights for the darkroom. In 1912, Eastman Kodak Company acquired Wratten and Wainwright because they were interested in the skills Mees provided. George Eastman convinced Mees to move to Rochester, New York, United States, where Mees created the Kodak Research Laboratories, becoming its first director. Mees helped the US military in World War I in its instruction of photography. After the attack on Pearl Harbor, Mees became an American citizen so tha ...

Royal Photographic Society
The Royal Photographic Society of Great Britain, commonly known as the Royal Photographic Society (RPS), is the world's oldest photographic society having been in continuous existence since 1853. It was founded in London, England, in 1853 as the Photographic Society of London with the objective of promoting the art and science of photography, and in the same year, received Monarchy of the United Kingdom, royal patronage from then-Queen Victoria and Albert, Prince Consort, Prince Albert. A change to the society's name to reflect the patronage was, however, not considered expedient at the time. In 1874, it was renamed the Photographic Society of Great Britain, and only from 1894 did it become known as the Royal Photographic Society of Great Britain, a title which it continues to use today. On 25 June 2019, the Duchess of Cambridge, now Catherine, Princess of Wales, became the Society's Patron, taking over from Queen Elizabeth II who had been patron since 1952. A registered Charit ...

The Century Magazine
''The Century Magazine'' was an illustrated monthly magazine first published in the United States in 1881 by The Century Company of New York City, which had been bought in that year by Roswell Smith and renamed by him after the Century Association. It was the successor of ''Scribner's Monthly, Scribner's Monthly Magazine''. It was merged into ''The Forum (American magazine), The Forum'' in 1930. History The initial editor was to have been Scribner's editor and co-owner Josiah Gilbert Holland, Josiah G. Holland, but he died prior to the appearance of the first issue. He was succeeded by Richard Watson Gilder, the managing editor of Scribner's, who would go on to helm ''The Century'' for 28 years. Gilder largely continued the mixture of literature, history, current events, and high-quality illustrations that Holland had used at Scribner's. The magazine was very successful during the 19th century, most notably for a series of articles about the American Civil War which ran for three ...

Silver Halide
A silver halide (or silver salt) is one of the chemical compounds that can form between the Chemical element, element silver (Ag) and one of the halogens. In particular, bromine (Br), chlorine (Cl), iodine (I) and fluorine (F) may each combine with silver to produce silver bromide (AgBr), silver chloride (AgCl), silver iodide (AgI), and four forms of silver fluoride, respectively. As a group, they are often referred to as the silver halides, and are often given the pseudo-chemical notation AgX. Although most silver halides involve silver atoms with oxidation states of +1 (Ag+), silver halides in which the silver atoms have oxidation states of +2 (Ag2+) are known, of which silver(II) fluoride is the only known stable one. Silver halides are light-sensitive chemicals, and are commonly used in photographic film and paper. Applications Light sensitivity Silver halides are used in photographic film and photographic paper, including graphic art film and paper, where silver halide cry ...
