Timeline Of Photography Technology
The following list comprises significant milestones in the development of photography technology. Timeline Prior to the 19th century * 1614 – In ''Septem planetarum terrestrium spagirica recensio,'' Angelo Sala reported that "Si lapidem lunearem pulveratum ad solem exponas instar atramenti niggerimus" (When you expose powdered silver nitrate to sunlight, it turns black as ink), and also its effect on paper; silver nitrate wrapped in paper for a year turned black. * c. 1717 – Johann Heinrich Schulze makes fleeting sun prints of words by using stencils, sunlight, and a bottled mixture of chalk and silver nitrate in nitric acid, simply as an interesting way to demonstrate that the substance inside the bottle darkens where it is exposed to light. * c. 1794 – Elizabeth Fulhame invented the concept of catalysis and discovered photoreduction. She describes catalysis as a process at length in her 1794 book ''An Essay On Combustion with a View to a New Art of Dying and P ...

Theory Of Colours
''Theory of Colours'' (german: Zur Farbenlehre, links=no) is a book by Johann Wolfgang von Goethe about the poet's views on the nature of colours and how these are perceived by humans. It was published in German in 1810 and in English in 1840. The book contains detailed descriptions of phenomena such as coloured shadows, refraction, and chromatic aberration. The work originated in Goethe's occupation with painting and mainly exerted an influence on the arts (Philipp Otto Runge, J. M. W. Turner, the Pre-Raphaelites, Hilma af Klint, Wassily Kandinsky). The book is a successor to two short essays entitled "Contributions to Optics". Although Goethe's work was rejected by some physicists, a number of philosophers and physicists have concerned themselves with it, including Thomas Johann Seebeck, Arthur Schopenhauer (see: '' On Vision and Colors''), Hermann von Helmholtz, Ludwig Wittgenstein, Werner Heisenberg, Kurt Gödel, and Mitchell Feigenbaum. Goethe's book pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hércules Florence
Antoine Hercule Romuald Florence (February 29, 1804 – March 27, 1879) was a Monegasque-Brazilian painter and inventor, known as the isolate inventor of photography in Brazil, three years before Daguerre (but six years after Nicéphore Niépce), using the matrix negative/positive, still in use. According to Kossoy, who examined Florence's notes, he referred to his process, in French, as ''photographie'' in 1834, at least four years before John Herschel coined the English word ''photography''. Early life Hercules Florence was born on February 29, 1804 in Nice, France, the son of Arnaud Florence (1749–1807), a tax collector, and Augustine de Vignolis, a minor noblewoman. As a child he manifested interest for drawing and the sciences, as well as for the voyages of the great explorers to the New World and already as a 14-year-old boy he worked as a calligrapher and draftsman in Monaco, where his parents had been living since 1807. After a period of wandering and working on board ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
View From The Window At Le Gras
''View from the Window at Le Gras'' is a heliographic image and the oldest surviving camera photograph. It was created by French inventor Nicéphore Niépce in 1827 in Saint-Loup-de-Varennes, France, and shows parts of the buildings and surrounding countryside of his estate, '' Le Gras'', as seen from a high window. Creation Niépce captured the scene with a camera obscura projected onto a pewter plate thinly coated with bitumen of Judea, a naturally occurring asphalt. The bitumen hardened in the brightly lit areas, but in the dimly lit areas it remained soluble and could be washed away with a mixture of oil of lavender and white petroleum. A very long exposure in the camera was required. Sunlight strikes the buildings on opposite sides, suggesting an exposure that lasted about eight hours, which has become the traditional estimate. A researcher who studied Niépce's notes and recreated his processes found that the exposure must have continued for several days. Early histo ...

Proceedings Of The Royal Society
''Proceedings of the Royal Society'' is the main research journal of the Royal Society. The journal began in 1831 and was split into two series in 1905: * Series A: for papers in physical sciences and mathematics. * Series B: for papers in life sciences. Many landmark scientific discoveries are published in the Proceedings, making it one of the most historically significant science journals. The journal contains several articles written by the most celebrated names in science, such as Paul Dirac, Werner Heisenberg, Ernest Rutherford, Erwin Schrödinger, William Lawrence Bragg, Lord Kelvin, J.J. Thomson, James Clerk Maxwell, Dorothy Hodgkin and Stephen Hawking. In 2004, the Royal Society began ''The Journal of the Royal Society Interface'' for papers at the interface of physical sciences and life sciences. History The journal began in 1831 as a compilation of abstracts of papers in the ''Philosophical Transactions of the Royal Society'', the older Royal Society publication ...

Mary Somerville
Mary Somerville (; , formerly Greig; 26 December 1780 – 29 November 1872) was a Scottish scientist, writer, and polymath. She studied mathematics and astronomy, and in 1835 she and Caroline Herschel were elected as the first female Honorary Members of the Royal Astronomical Society. When John Stuart Mill organized a massive petition to Parliament to give women the right to vote, he made sure that the first signature on the petition would be Somerville's. In 1834 she became the first person to be described in print as a 'scientist'. When she died in 1872, '' The Morning Post'' declared in her obituary that "Whatever difficulty we might experience in the middle of the nineteenth century in choosing a king of science, there could be no question whatever as to the queen of science". Somerville College, a college of the University of Oxford, is named after her, reflecting the virtues of liberalism and academic success which the college wished to embody. She is featured on the ...

Lithographic Limestone
Lithographic limestone is hard limestone that is sufficiently fine-grained, homogeneous and defect free to be used for lithography. Geologists use the term "lithographic texture" to refer to a grain size under 1/250 mm. The term "sublithographic" is sometimes used for homogeneous fine-grained limestone with a somewhat coarser texture. Origin The generally accepted theory for the origin of lithographic and sublithographic limestones is that they were formed in shallow, stagnant, hypersaline, and anoxic lagoons. The combination of mild hypersalinity and low oxygen content is believed to have inhibited the formation of microbial mats and prevented the invasion of bottom dwelling organisms. Microbial mats and bottom dwelling organisms would have left fossils, and bottom dwelling organisms would have churned the accumulating sediment, producing a less homogeneous rock. Stagnancy was required to avoid churning or sculpting of the sediment by currents or wave action.Walter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heliography
Heliography (in French, ''héliographie)'' from ''helios'' (Greek: ''ἥλιος'')'','' meaning "sun"'','' and ''graphein (γράφειν),'' "writing") is the photographic process invented, and named thus, by Joseph Nicéphore Niépce around 1822, which he used to make the earliest known surviving photograph from nature, ''View from the Window at Le Gras'' (1826 or 1827), and the first realisation of photoresist as means to reproduce artworks through inventions of photolithography and photogravure. Invention Nicéphore Niépce began experiments with the aim of achieving a photo-etched printmaking technique in 1811. He knew that the acid-resistant Bitumen of Judea used in etching hardened with exposure to light. In experiments he coated it on plates of glass, zinc, copper and silver-surfaced copper, pewter and limestone (lithography), and found the surface exposed to the most light resisted dissolution in oil of lavender and petroleum, so that the uncoated shadow areas m ...

Contact Print
A contact print is a photographic image produced from film; sometimes from a film negative, and sometimes from a film positive or paper negative. In a darkroom an exposed and developed piece of film or photographic paper is placed emulsion side down, in contact with a piece of photographic paper, light is briefly shone through the negative or paper and then the paper is developed to reveal the final print. The defining characteristic of a contact print is that the resulting print is the same size as the original, rather than having been projected through an enlarger. Basic tools Contact printing is a simple and inexpensive process. Its simplicity avails itself to those who may want to try darkroom processing without buying an enlarger. One or more negatives are placed on a sheet of photographic paper which is briefly exposed to a light source. The light may come from a low wattage frosted bulb hanging above an easel which holds them together, or contained in an expos ...

Pope Pius VII
Pope Pius VII ( it, Pio VII; born Barnaba Niccolò Maria Luigi Chiaramonti; 14 August 1742 – 20 August 1823), was head of the Catholic Church and ruler of the Papal States from 14 March 1800 to his death in August 1823. Chiaramonti was also a monk of the Order of Saint Benedict in addition to being a well-known theologian and bishop. Chiaramonti was made Bishop of Tivoli in 1782, and resigned that position upon his appointment as Bishop of Imola in 1785. That same year, he was made a cardinal. In 1789, the French Revolution took place, and as a result a series of anti-clerical governments came into power in the country. In 1796, during the French Revolutionary Wars, French troops under Napoleon Bonaparte invaded Rome and captured Pope Pius VI, taking him as a prisoner to France, where he died in 1799. The following year, after a ''sede vacante'' period lasting approximately six months, Chiaramonti was elected to the papacy, taking the name Pius VII. Pius at first attempted to ...

Bitumen Of Judea
Bitumen of Judea, or Syrian asphalt, is a naturally occurring asphalt that has been put to many uses since ancient times. Wood coloration usage Bitumen of Judea may be used as a colorant for wood for an aged, natural and rustic appearance. It is soluble in turpentine and some other terpenes, and can be combined with oils, waxes, varnishes and glazes. Light-sensitive properties It is a light-sensitive material in what is accepted to be the first complete photographic process, i.e., one capable of producing durable light-fast results. The technique was developed by French scientist and inventor Nicéphore Niépce in the 1820s. In 1826 or 1827, he applied a thin coating of the tar-like material to a pewter plate and took a picture of parts of the buildings and surrounding countryside of his estate, producing what is usually described as the first photograph. It is considered to be the oldest known surviving photograph made in a camera. The plate was exposed in the camera for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 three 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 ...
