Thomas Sutton (photographer)
Thomas Sutton (c. 1819 – 19 March 1875, in Kensington) was an English photographer, author, and inventor. Life Thomas Sutton went to school in Newington Butts and studied architecture for four years before studying at Caius College, Cambridge graduating in 1846 as the 29th wrangler. He opened a photographic studio in Jersey the following year under the patronage of Prince Albert. In 1855 he set up a photographic company in Jersey with business partner Louis Désiré Blanquart-Evrard that produced prints from calotype negatives. The following year, Sutton and Blanquart-Evrard founded the journal ''Photographic Notes'', which Sutton edited for eleven years. A prolific author, Sutton wrote a number of books on the subject of photography, including the ''Dictionary of Photography'' in 1858. In 1859, Sutton developed the earliest panoramic camera with a wide-angle lens. The lens consisted of a glass sphere filled with water, which projected an image onto a curved plate. The ...

Tartan Ribbon
Tartan or plaid ( ) is a patterned cloth consisting of crossing horizontal and vertical bands in multiple colours, forming repeating symmetrical patterns known as ''setts''. Originating in woven wool, tartan is most strongly associated with Scotland, where it has been used for centuries in traditional clothing such as the kilt. Historically, specific tartans were linked to Scottish clans, families, or regions, with patterns and colours derived from local dyes. The earliest surviving samples of tartan-style cloth are around 3,000 years old and were discovered in Xinjiang, China. Tartan became a symbol of Scottish identity, especially from the 16th century onward, despite bans following the Jacobite rising of 1745 under the Dress Act 1746. The 19th-century Highland Revival popularized tartan globally, associating it with Highland dress and the Scottish diaspora. Today, tartan is used worldwide in clothing, accessories, and design, transcending its traditional roots. M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Filter (optics)
An optical filter is a device that selectively transmits light of different wavelengths, usually implemented as a glass plane or plastic device in the optical path, which are either dyed in the bulk or have interference coatings. The optical properties of filters are completely described by their frequency response, which specifies how the magnitude and phase of each frequency component of an incoming signal is modified by the filter. Filters mostly belong to one of two categories. The simplest, physically, is the absorptive filter; then there are interference or dichroic filters. Many optical filters are used for optical imaging and are manufactured to be transparent; some used for light sources can be translucent. Optical filters selectively transmit light in a particular range of wavelengths, that is, colours, while absorbing the remainder. They can usually pass long wavelengths only (longpass), short wavelengths only (shortpass), or a band of wavelengths, bloc ...

1810s Births
Year 181 ( CLXXXI) was a common year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Burrus (or, less frequently, year 934 ''Ab urbe condita''). The denomination 181 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Imperator Lucius Aurelius Commodus and Lucius Antistius Burrus become Roman Consuls. * The Antonine Wall is overrun by the Picts in Britannia (approximate date).

19th-century English Photographers
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and confirm ce ...

Colour Vision
Color vision, a feature of visual perception, is an ability to perceive differences between light composed of different frequencies independently of light intensity. Color perception is a part of the larger visual system and is mediated by a complex process between neurons that begins with differential stimulation of different types of Photoreceptor cell, photoreceptors by light entering the eye. Those photoreceptors then emit outputs that are propagated through many layers of neurons ultimately leading to higher Cognition, cognitive functions in the brain. Color vision is found in many animals and is mediated by similar underlying mechanisms with common types of biological molecules and a complex history of the evolution of color vision within different animal taxon, taxa. In primates, color vision may have evolved under selective pressure for a variety of visual tasks including the foraging for nutritious young leaves, ripe fruit, and flowers, as well as detecting predator camo ...

Sergey Prokudin-Gorsky
Sergey Mikhaylovich Prokudin-Gorsky ( rus, Сергей Михайлович Прокудин-Горский, p=sʲɪrˈɡʲej mʲɪˈxajləvʲɪtɕ prɐˈkudʲɪn ˈɡorskʲɪj, a=ru-Prokudin-Gorskii.ogg; – September 27, 1944) was a Russian chemist and photographer. He is best known for his pioneering work in colour photography and his effort to document early 20th-century Russia. Using a railway-car darkroom provided by Emperor of all the Russias, Emperor Nicholas II, Prokudin-Gorsky travelled the Russian Empire from around 1909 to 1915 using his three-image colour photography to record its many aspects. While some of his negatives were lost, the majority ended up in the US Library of Congress after his death. Starting in 2000, the negatives were digitised and the colour triples for each subject digitally combined to produce hundreds of high-quality colour images of Russia and its neighbours from over a century ago.

Panchromatic
A panchromatic emulsion is a type of photographic emulsion that is sensitive to all wavelengths of visible light, and produces a monochrome photograph—typically black and white. Most modern commercially available film is panchromatic, and the technology is usually contrasted with earlier methods that cannot register all wavelengths, especially orthochromatic film. In digital imaging, a panchromatic sensor is an image sensor or array of sensors that combine the visible spectrum with non-visible wavelengths, such as ultraviolet or infrared. Images produced are also black and white, and the system is used for its ability to produce higher resolution images than standard digital sensors. Description A panchromatic emulsion renders a realistic reproduction of a scene as it appears to the human eye, although with no colors. Almost all modern photographic film is panchromatic. Some older types of film were orthochromatic and were not sensitive to certain wavelengths of light. As ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gamut
In color reproduction and colorimetry, a gamut, or color gamut , is a convex set containing the colors that can be accurately represented, i.e. reproduced by an output device (e.g. printer or display) or measured by an input device (e.g. camera or visual system). Devices with a larger gamut can represent more colors. Similarly, gamut may also refer to the colors within a defined color space, which is not linked to a specific device. A trichromatic gamut is often visualized as a color triangle. A less common usage defines gamut as the subset of colors contained within an image, scene or video. Introduction The term ''gamut'' was adopted from the field of music, where the medieval Latin expression "gamma ut" meant the lowest tone of the G scale and, in time, came to imply the entire range of musical notes of which musical melodies are composed. William Shakespeare, Shakespeare's use of the term in ''The Taming of the Shrew'' is sometimes attributed to the author / musician Thom ...

Additive Colour
Additive color or additive mixing is a property of a color model that predicts the appearance of colors made by coincident component lights, i.e. the perceived color can be predicted by summing the numeric representations of the component colors. Modern formulations of Grassmann's laws describe the additivity in the color perception of light mixtures in terms of algebraic equations. Additive color predicts perception and not any sort of change in the photons of light themselves. These predictions are only applicable in the limited scope of color matching experiments where viewers match small patches of uniform color isolated against a gray or black background. Additive color models are applied in the design and testing of electronic displays that are used to render realistic images containing diverse sets of color using phosphors that emit light of a limited set of primary colors. Examination with a sufficiently powerful magnifying lens will reveal that each pixel in CRT, LCD ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thought-experiment
A thought experiment is an imaginary scenario that is meant to elucidate or test an argument or theory. It is often an experiment that would be hard, impossible, or unethical to actually perform. It can also be an abstract hypothetical that is meant to test our intuitions about morality or other fundamental philosophical questions. History The ancient Greek , "was the most ancient pattern of mathematical proof", and existed before Euclidean mathematics, where the emphasis was on the conceptual, rather than on the experimental part of a thought experiment. Johann Witt-Hansen established that Hans Christian Ørsted was the first to use the equivalent German term . Ørsted was also the first to use the equivalent term in 1820. By 1883, Ernst Mach used in a different sense, to denote exclusively the conduct of a experiment that would be subsequently performed as a by his students. Physical and mental experimentation could then be contrasted: Mach asked his students to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
