139-558: Helmut Erich Robert Kuno Gernsheim (1 March 1913 – 20 July 1995) was a historian of photography , a collector and a photographer. Born in Munich , Germany, he was the third son of the academic librarian Karl Gernsheim and his wife Hermine Scholz. He studied art history at the Ludwig Maximilian University of Munich . He took up photography in 1934 at the urging of his brother, de:Walter Gernsheim , who thought it
278-486: A subtractive color image. Maxwell's method of taking three separate filtered black-and-white photographs continued to serve special purposes into the 1950s and beyond, and Polachrome , an "instant" slide film that used the Autochrome's additive principle, was available until 2003, but the few color print and slide films still being made in 2015 all use the multilayer emulsion approach pioneered by Kodachrome. In 1957,
417-484: A Music Department. At the time, such musical publishing enterprises, however, were rare. and few of the Delegates or former Publishers were themselves musical or had extensive music backgrounds. OUP bought an Anglo-French Music Company and all its facilities, connections, and resources. This concentration provided OUP two mutually reinforcing benefits: a niche in music publishing unoccupied by potential competitors and
556-497: A Tomlin order, a damages settlement under which the servants and agents of Oxford University are permanently barred from denigrating Malcolm or Making Names , rendering it the first book in literary history to be afforded such legal protection. The case was reported to have cost Oxford over £500,000. In November 1998, OUP announced the closure, on commercial grounds, of its modern poetry list. Andrew Potter, OUP's director of music, trade paperbacks and Bibles, told The Times that
695-533: A branch of music performance and composition that the English themselves had largely neglected. Hinnells proposes that the early Music Department's "mixture of scholarship and cultural nationalism" in an area of music with largely unknown commercial prospects was driven by its sense of cultural philanthropy (given the press's academic background) and a desire to promote "national music outside the German mainstream." It
834-540: A camera obscura device. He did not manage to properly fix his images and abandoned the project after hearing of the Daguerreotype process in 1839 and did not properly publish any of his findings. He reportedly referred to the technique as "photographie" (in French) as early as 1833, also helped by a suggestion of De Mello. Some extant photographic contact prints are believed to have been made in circa 1833 and kept in
973-407: A facsimile of the image. The mirror represents images faithfully, but retains none; our canvas reflects them no less faithfully, but retains them all. This impression of the image is instantaneous. The canvas is then removed and deposited in a dark place. An hour later the impression is dry, and you have a picture the more precious in that no art can imitate its truthfulness." De la Roche thus imagined
1112-607: A fatwa urging the execution of British author Salman Rushdie and of all involved in the publication of his novel The Satanic Verses . Rushdie went into hiding, and an international movement began to boycott book trading with Iran. There was, therefore, outrage when, in April 1989, OUP broke the worldwide embargo and chose to attend the Tehran Book Fair . OUP justified this by saying, "We deliberated about it quite deeply but felt it certainly wasn't in our interests, or Iran's as
1251-464: A filter of a yellowish-orange color was required to keep the photograph from coming out excessively blue. Although necessary, the filter had the effect of reducing the amount of light that was absorbed. Another drawback was that the image could only be enlarged so much before the many dots that made up the image would become apparent. Competing screen plate products soon appeared, and film-based versions were eventually made. All were expensive, and until
1390-467: A fixer, because the highly acclaimed scientist Davy had already tried and failed. Apparently the article was not noted by Niépce or Daguerre, and by Talbot only after he had developed his own processes. French balloonist, professor and inventor Jacques Charles is believed to have captured fleeting negative photograms of silhouettes on light-sensitive paper at the start of the 19th century, prior to Wedgwood. Charles died in 1823 without having documented
1529-496: A fortune through his shares in the business and the acquisition and renovation of the bankrupt paper mill at Wolvercote. Combe showed little interest, however, in producing fine printed work at the press. The best-known text associated with his print shop was the flawed first edition of Alice's Adventures in Wonderland , printed by Oxford at the expense of its author Lewis Carroll (Charles Lutwidge Dodgson) in 1865. It took

#17327756064181668-582: A free gift. Complete instructions were made public on 19 August 1839. Known as the daguerreotype process, it was the most common commercial process until the late 1850s when it was superseded by the collodion process . French-born Hércules Florence developed his own photographic technique in 1832 or 1833 in Brazil, with some help of pharmacist Joaquim Corrêa de Mello (1816–1877). Looking for another method to copy graphic designs he captured their images on paper treated with silver nitrate as contact prints or in
1807-498: A home for his vast collection of over 33,000 photographs, 4,000 books, research notes, his own correspondence, and collected correspondence including letters by Daguerre and Fox Talbot. He sought unsuccessfully to found a national museum of photography in the UK (ultimately a National Museum did not happen until 1983). In the end, after many fruitless discussions with authorities and potential sponsors in several countries, he sold everything to
1946-485: A huge collection containing work by Julia Margaret Cameron , Alvin Langdon Coburn , Hill & Adamson , William Henry Fox Talbot and Louis Daguerre . They rediscovered the long-lost hobby of Lewis Carroll when, in 1947, Gernsheim stumbled across an album of Carroll's portraits in a junk shop. Ultimately this collection, along with an estimated 3–4 million words of notes on the subject, led to his writing
2085-505: A large number of positive prints by simple contact printing . The calotype had yet another distinction compared to other early photographic processes, in that the finished product lacked fine clarity due to its translucent paper negative. This was seen as a positive attribute for portraits because it softened the appearance of the human face . Talbot patented this process, which greatly limited its adoption, and spent many years pressing lawsuits against alleged infringers. He attempted to enforce
2224-517: A major printer of Bibles, prayer books, and scholarly works. Oxford's chancellor Archbishop William Laud consolidated the legal status of the university's printing in the 1630s and petitioned Charles I for rights that would enable Oxford to compete with the Stationers' Company and the King's Printer . He obtained a succession of royal grants, and Oxford's "Great Charter" in 1636 gave the university
2363-404: A mirror-like silver-surfaced plate that had been fumed with iodine vapor, which reacted with the silver to form a coating of silver iodide . As with the bitumen process, the result appeared as a positive when it was suitably lit and viewed. Exposure times were still impractically long until Daguerre made the pivotal discovery that an invisibly slight or "latent" image produced on such a plate by
2502-659: A more efficient alternative to his original hot salt water method. In 1837, mineralist-writer Franz von Kobell shot finely detailed salt-paper negatives of different perspectives of the Munich Frauenkirche and other local buildings. Kobell revealed his work in 1839, together with Carl August von Steinheil . The "Steinheil method" produced pictures with a diameter of 4 cm, and negatives were rephotographed to create positive versions. Talbot's early silver chloride "sensitive paper" experiments required camera exposures of an hour or more. In 1841, Talbot invented
2641-528: A more practical profession for someone from a partially Jewish background who intended to leave Nazi Germany. He graduated from the State School of Photography, Munich , after two years' study. Beginning in the late 1930s, he made commercial work, some in colour using the German Uvachrome process, before going to Paris for an exhibition of his work and then to London to work on commissions from
2780-480: A mosaic of tiny color filters overlaid on the emulsion and view the results through an identical mosaic. If the individual filter elements were small enough, the three primary colors of red, blue, and green would blend together in the eye and produce the same additive color synthesis as the filtered projection of three separate photographs. Autochrome plates had an integral mosaic filter layer with roughly five million previously dyed potato grains per square inch added to
2919-489: A much shorter exposure could be "developed" to full visibility by mercury fumes. This brought the required exposure time down to a few minutes under optimum conditions. A strong hot solution of common salt served to stabilize or fix the image by removing the remaining silver iodide. On 7 January 1839, this first complete practical photographic process was announced at a meeting of the French Academy of Sciences, and

The camera lucida projects an optical image of the subject being viewed, on the surface upon which the artist is drawing. The artist sees both scene and drawing surface simultaneously, as in a photographic double exposure. This allows the artist to duplicate key points of
3197-487: A process for making glass plates with an albumen emulsion; the Langenheim brothers of Philadelphia and John Whipple and William Breed Jones of Boston also invented workable negative-on-glass processes in the mid-1840s. In 1851, English sculptor Frederick Scott Archer invented the collodion process . Photographer and children's author Lewis Carroll used this process. Carroll refers to the process as "Talbotype" in
3336-589: A process that made use of a special substance in combination with the qualities of a mirror, rather than the camera obscura. The dark place in which the pictures dried suggests that he thought about the light sensitivity of the material, but he attributed the effect to its viscous nature. In 1777, the chemist Carl Wilhelm Scheele was studying the more intrinsically light-sensitive silver chloride and determined that light darkened it by disintegrating it into microscopic dark particles of metallic silver. Of greater potential usefulness, Scheele found that ammonia dissolved
3475-583: A rediscovery of the Baroque monuments". Around this time, he won a coveted position with the Warburg Institute as the chief photographer for the London area. He joined The Royal Photographic Society in 1940 became a Fellow (FRPS) in 1942. He met his future wife, Alison, in 1938 and, after she and her first husband, Blen Williams, divorced, they set up home together in 1942 and married at the end of
3614-561: A set of three color-filtered black-and-white photographs in color without having to project them, and for using them to make full-color prints on paper. The first widely used method of color photography was the Autochrome plate, a process inventors and brothers Auguste and Louis Lumière began working on in the 1890s and commercially introduced in 1907. It was based on one of Louis Duclos du Haroun's ideas: instead of taking three separate photographs through color filters, take one through
3753-517: A silver nitrate solution. Attempts to preserve the results with their "distinct tints of brown or black, sensibly differing in intensity" failed. It is unclear when Wedgwood's experiments took place. He may have started before 1790; James Watt wrote a letter to Thomas Wedgwood's father Josiah Wedgwood to thank him "for your instructions as to the Silver Pictures, about which, when at home, I will make some experiments". This letter (now lost)
3892-512: A small opening onto an opposite surface. This principle may have been known and used in prehistoric times. The earliest known written record of the camera obscura is to be found in the 4th century BCE, in two different places in parallel: by Aristotle in Greece and by Mozi in China. Alhazen (or Ibn al-Haytham) is said to be the first that actually built a camera obscura. Until the 16th century

Indeed they always are. But we don't expect
4170-631: A stereoscope with lenses and a binocular camera in 1844. He presented two stereoscopic self portraits made by John Adamson in March 1849. A stereoscopic portrait of Adamson in the University of St Andrews Library Photographic Archive, dated "circa 1845', may be one of these sets. A stereoscopic daguerreotype portrait of Michael Faraday in Kingston College's Wheatstone collection and on loan to Bradford National Media Museum, dated "circa 1848", may be older. A practical means of color photography

4448-470: A ubiquitous everyday practice around the world. The coining of the word "photography" is usually attributed to Sir John Herschel in 1839. It is based on the Greek φῶς ( phōs ; genitive phōtos ), meaning "light", and γραφή ( graphê ), meaning "drawing, writing", together meaning "drawing of light". A natural phenomenon, known as camera obscura or pinhole image, can project a (reversed) image through

Nonetheless, Talbot's developed-out silver halide negative process is the basic technology used by chemical film cameras today. Hippolyte Bayard had also developed a method of photography but delayed announcing it, and so
5004-472: A victory over its oppressors". The Appeal Court judges were highly critical of Oxford's conduct of the affair and the litigation. Lord Justice Mustill declared, "The Press is one of the longest-established publishing houses in the United Kingdom, and no doubt in the world. They must have been aware from the outset that the absence of agreement on the matters in question [the book's print-run and format]

In 1990, in the UK Court of Appeal, author Andrew Malcolm won a landmark legal judgment against Oxford University (Press) for its breach of a contract to publish his philosophical text Making Names . Reporting on the verdict in The Observer , Laurence Marks wrote, "It is the first time in living memory that Grub Street has won such

It suffered from the absence of any figure comparable to Fell. The business was rescued by the intervention of a single Delegate, William Blackstone . Disgusted by the chaotic state of the press and antagonized by Vice-Chancellor George Huddesford , Blackstone called for sweeping reforms that would firmly set out
5421-469: A wider readership. Equally, Price moved OUP towards publishing in its own right. The press had ended its relationship with Parker's in 1863 and, in 1870, bought a small London bindery for some Bible work. Macmillan's contract ended in 1880 and was not renewed. By this time, Oxford also had a London warehouse for Bible stock in Paternoster Row , and in 1880, its manager, Henry Frowde (1841–1927),

He originally wanted to capture the images of a camera obscura, but found they were too faint to have an effect upon the silver nitrate solution that was recommended to him as a light-sensitive substance. Wedgwood did manage to copy painted glass plates and captured shadows on white leather, as well as on paper moistened with

The label "Clarendon Press" took on a new meaning when OUP began publishing books through its London office in the early 20th century. To distinguish the two offices, London books were labelled "Oxford University Press" publications, while those from Oxford were labelled "Clarendon Press" books. This labelling ceased in

In 1884, the year he retired as Secretary, the Delegates bought back the last shares in the business. The press was now owned wholly by the university, with its own paper mill, print shop, bindery, and warehouse. Its output had increased to include school books and modern scholarly texts such as James Clerk Maxwell 's A Treatise on Electricity & Magnetism (1873), which proved fundamental to Einstein's thought. Without abandoning its traditions or quality of work, Price began to turn OUP into an alert, modern publisher. In 1879, he also took on

Paper with a coating of silver iodide was exposed in the camera and developed into a translucent negative image. Unlike a daguerreotype, which could only be copied by photographing it with a camera, a calotype negative could be used to make

He continued a positive interest in photography, vigorously supporting the establishment of photographic galleries and museums in the USA and Britain, including The Photographers' Gallery under Sue Davies in 1971 and the National Museum of Photography Film and Television under Colin Ford in 1983. Helmut Gernsheim died on 20 July 1995. Ultimately, Gernsheim needed to find
10286-424: The assembled Chancellor, Masters and Scholars of the University of Oxford the appellant has had a fair crack of the whip. I certainly do not... Mr Charkin took the decision [to renege on the OUP editor's contract], not because he thought the book was no good - he had never seen it and the reports were favourable - but because he thought it would not sell. Let there be no mistake about it, the failure of this transaction
10425-450: The bitumen process, substituting a more sensitive resin and a very different post-exposure treatment that yielded higher-quality and more easily viewed images. Exposure times in the camera, although substantially reduced, were still measured in hours. Niépce died suddenly in 1833, leaving his notes to Daguerre. More interested in silver-based processes than Niépce had been, Daguerre experimented with photographing camera images directly onto
10564-596: The bitumen was sufficiently hardened in proportion to its exposure to light that the unhardened part could be removed with a solvent, leaving a positive image with the light areas represented by hardened bitumen and the dark areas by bare pewter. To see the image plainly, the plate had to be lit and viewed in such a way that the bare metal appeared dark and the bitumen relatively light. In partnership, Niépce in Chalon-sur-Saône and Louis Daguerre in Paris refined
10703-555: The book by giving him a valueless assurance would be tantamount to an imputation of fraud... It follows that in my judgment when Mr Hardy used the expressions 'commitment' and 'a fair royalty' he did in fact mean what he said; and I venture to think that it would take a lawyer to arrive at any other conclusion. There was therefore an enforceable contract for the publication of Mr Malcolm's book... The Respondents' final statement may be thought unworthy of them." The case ended in July 1992 with
10842-602: The button, we do the rest". Now anyone could take a photograph and leave the complex parts of the process to others, and photography became available for the mass-market in 1901 with the introduction of the Kodak Brownie . Charles Wheatstone developed his mirror stereoscope around 1832, but did not really publicize his invention until June 1838. He recognized the possibility of a combination with photography soon after Daguerre and Talbot announced their inventions and got Henry Fox Talbot to produce some calotype pairs for
10981-436: The camera obscura was mainly used to study optics and astronomy, especially to safely watch solar eclipses without damaging the eyes. In the later half of the 16th century some technical improvements were developed: a biconvex lens in the opening (first described by Gerolamo Cardano in 1550) and a diaphragm restricting the aperture ( Daniel Barbaro in 1568) gave a brighter and sharper image. In 1558 Giambattista della Porta
11120-437: The camera obscura. In 1614 Angelo Sala noted that sunlight will turn powdered silver nitrate black, and that paper wrapped around silver nitrate for a year will turn black. Wilhelm Homberg described how light darkened some chemicals in 1694. Around 1717, German polymath Johann Heinrich Schulze accidentally discovered that a slurry of chalk and nitric acid into which some silver particles had been dissolved
11259-567: The collection of IMS. Henry Fox Talbot had already succeeded in creating stabilized photographic negatives on paper in 1835, but worked on perfecting his own process after reading early reports of Daguerre's invention. In early 1839, he acquired a key improvement, an effective fixer, from his friend John Herschel , a polymath scientist who had previously shown that hyposulfite of soda (commonly called "hypo" and now known formally as sodium thiosulfate ) would dissolve silver salts. News of this solvent also benefited Daguerre, who soon adopted it as
11398-465: The composer Ray Martin, the artist Johannes Koelz, the photographers Henry Talbot and Hans Axel, the art historians Franz Phillipp and Ernst Kitzinger , the author Ulrich Boschwitz, the furniture designers Fred Lowen and Ernst Roedeck, and Erwin Fabian (sculptor). While interned, he lectured other internees on the aesthetics of photography and wrote his critique on photography, New Photo Vision , which
11537-648: The demand for portraiture that emerged from the middle classes during the Industrial Revolution . This demand, which could not be met in volume and in cost by oil painting, added to the push for the development of photography. Roger Fenton and Philip Henry Delamotte helped popularize the new way of recording events, the first by his Crimean War pictures, the second by his record of the disassembly and reconstruction of The Crystal Palace in London . Other mid-nineteenth-century photographers established
11676-620: The details of the process to the Chamber of Peers in Paris. On August 19 the technical details were made public in a meeting of the Academy of Sciences and the Academy of Fine Arts in the Palace of Institute. (For granting the rights of the inventions to the public, Daguerre and Niépce were awarded generous annuities for life.) When the metal based daguerreotype process was demonstrated formally to
11815-561: The experiments. Although the journal of the nascent Royal Institution probably reached its very small group of members, the article must have been read eventually by many more people. It was reviewed by David Brewster in the Edinburgh Magazine in December 1802, appeared in chemistry textbooks as early as 1803, was translated into French and was published in German in 1811. Readers of the article may have been discouraged to find
11954-652: The first edition was not completed until 1928, 13 years after Murray's death, costing around £375,000. This vast financial burden and its implications landed on Price's successors. The next Secretary, Philip Lyttelton Gell , was appointed by the Vice-Chancellor Benjamin Jowett in 1884 but struggled and was finally dismissed in 1897. The Assistant Secretary, Charles Cannan, was instrumental in Gell's removal. Cannan took over with little fuss and even less affection for his predecessor in 1898: "Gell
12093-456: The first photo taken in Egypt; that of Ras El Tin Palace . In America, by 1851 a broadsheet by daguerreotypist Augustus Washington was advertising prices ranging from 50 cents to $ 10. However, daguerreotypes were fragile and difficult to copy. Photographers encouraged chemists to refine the process of making many copies cheaply, which eventually led them back to Talbot's process. Ultimately,
12232-543: The first university presses to publish an open access journal ( Nucleic Acids Research ), and probably the first to introduce so-called hybrid open access journals , offering "optional open access" to authors, which provides all readers with online access to their paper free of charge. The "Oxford Open" model applies to the majority of their journals. OUP is a member of the Open Access Scholarly Publishers Association . OUP
12371-599: The formula alkaline . The new formula was sold by the Platinotype Company in London as Sulphur-Pyrogallol Developer. Nineteenth-century experimentation with photographic processes frequently became proprietary. The German-born, New Orleans photographer Theodore Lilienthal successfully sought legal redress in an 1881 infringement case involving his "Lambert Process" in the Eastern District of Louisiana. The daguerreotype proved popular in response to
12510-425: The foundation of Sweden's Fotografiska Museet formally established in 1971. Museum Folkwang , Essen, Germany, a division of the Museum of Modern Art, is one of Germany's most important collections of photographs, begun after its first exhibition of photographs from Gernsheim's collection surveying over 100 years of photography, and following which Otto Steinert purchased works by portrait photographer Hugo Erfurth and
12649-496: The gatekeepers themselves, the custodians, to be barbarians." Oxford's professor Valentine Cunningham wrote in the Times Higher Education Supplement : "Increasingly, (OUP) has behaved largely like a commercial outfit, with pound signs in its eyes and a readiness to dumb down for the sake of popularity and sales....Sacking poets not because they lose money but because they do not make enough of it: it
12788-520: The general reader, but also for schools and universities, under its Three Crowns Books imprint. Its territory includes Botswana , Lesotho , Swaziland , and Namibia , as well as South Africa, the biggest market of the five. OUP Southern Africa is now one of the three biggest educational publishers in South Africa. It focuses on publishing textbooks, dictionaries, atlases, supplementary material for schools, and university textbooks. Its author base
12927-556: The image being further affected by the light. The notion that light can affect various substances—for instance, the sun tanning of skin or fading of textile—must have been around since very early times. Ideas of fixing the images seen in mirrors or other ways of creating images automatically may also have been in people's minds long before anything like photography was developed. However, there seem to be no historical records of any ideas even remotely resembling photography before 1700, despite early knowledge of light-sensitive materials and
13066-445: The image formed in a camera was created by Niépce in 1826 or 1827. It was made on a polished sheet of pewter and the light-sensitive substance was a thin coating of bitumen , a naturally occurring petroleum tar, which was dissolved in lavender oil , applied to the surface of the pewter and allowed to dry before use. After a very long exposure in the camera (traditionally said to be eight hours, but now believed to be several days),
13205-485: The images formed in a small camera, but the photographs were negatives , darkest where the camera image was lightest and vice versa, and they were not permanent in the sense of being reasonably light-fast; like earlier experimenters, Niépce could find no way to prevent the coating from darkening all over when it was exposed to light for viewing. Disenchanted with silver salts , he turned his attention to light-sensitive organic substances. The oldest surviving photograph of
13344-537: The last 400 years, OUP has focused primarily on the publication of pedagogical texts. It continues this tradition today by publishing academic journals, dictionaries, English language resources, bibliographies, books on Indology , music, classics, literature, and history, as well as Bibles and atlases. OUP has offices around the world, primarily in locations that were once part of the British Empire . The University of Oxford began printing around 1480 and became
13483-442: The list "just about breaks even. The university expects us to operate on commercial grounds, especially in this day and age." In the same article, the poet D. J. Enright , who had been with OUP since 1979, said, "There was no warning. It was presented as a fait accompli. Even the poetry editor didn't know....The money involved is peanuts. It's a good list, built up over many years." In February 1999, Arts Minister Alan Howarth made
13622-470: The medium as a more precise means than engraving or lithography of making a record of landscapes and architecture: for example, Robert Macpherson 's broad range of photographs of Rome, the interior of the Vatican, and the surrounding countryside became a sophisticated tourist's visual record of his own travels. In 1839, François Arago reported the invention of photography to stunned listeners by displaying
13761-461: The new "public benefit" requirement of the revised Charities Act, the issue was re-examined with particular reference to OUP. In the same year, Malcolm obtained and posted the documents of OUP’s applications to the Inland Revenue for tax exemption in the 1940s and 1950s (unsuccessful) and the 1970s (successful). In 2008, CUP's and OUP's privilege was attacked by rival publishers. In 2009, The Guardian invited Andrew Malcolm to write an article on
13900-510: The news quickly spread. At first, all details of the process were withheld and specimens were shown only at Daguerre's studio, under his close supervision, to Academy members and other distinguished guests. Arrangements were made for the French government to buy the rights in exchange for pensions for Niépce's son and Daguerre and to present the invention to the world (with the exception of Great Britain, where an agent for Daguerre patented it) as
14039-480: The photogram and shadow images he managed to capture around 1800 (see below). Elizabeth Fulhame 's book An essay on combustion described her experiments of the effects of light on silver salts. She is better known for her discovery of what is now called catalysis , but Larry J. Schaaf in his history of photography considered her work on silver chemistry to represent a major step in the development of photography. English photographer and inventor Thomas Wedgwood
14178-490: The process, but purportedly demonstrated it in his lectures at the Louvre. It was not publicized until François Arago mentioned it at his introduction of the details of the daguerreotype to the world in 1839. He later wrote that the first idea of fixing the images of the camera obscura or the solar microscope with chemical substances belonged to Charles. Later historians probably only built on Arago's information, and, much later,
14317-572: The proposal get as far as the Finance Committee." Since the 1940s, both OUP and the Cambridge University Press (CUP), had made applications to the Inland Revenue for exemption from corporate tax. The first application, by CUP in 1940, was rejected "on the ground that, since the Press was printing and publishing for the outside world and not simply for the internal use of the University, the Press's trade went beyond
14456-473: The public, the competitor approach of paper-based calotype negative and salt print processes invented by William Henry Fox Talbot was already demonstrated in London (but with less publicity). Subsequent innovations made photography easier and more versatile. New materials reduced the required camera exposure time from minutes to seconds, and eventually to a small fraction of a second; new photographic media were more economical, sensitive or convenient. Since
14595-574: The publication that led that process to its conclusion: the massive project that became the Oxford English Dictionary (OED). Offered to Oxford by James Murray and the Philological Society , the "New English Dictionary" was a grand academic and patriotic undertaking. Lengthy negotiations led to a formal contract. Murray was to edit a work estimated to take ten years and to cost approximately £9,000. Both figures were wildly optimistic. The Dictionary began appearing in print in 1884, but
14734-508: The purpose and objects of the University and (in terms of the Act) was not exercised in the course of the actual carrying out of a primary purpose of the University." Similar applications by OUP in 1944 and 1950 were also rejected by the Inland Revenue, whose officers repeatedly pointed out that the university presses were in open competition with commercial, tax-liable publishers. In November 1975, CUP's chief executive Geoffrey Cass again applied to
14873-624: The right to print "all manner of books". Laud also obtained the "privilege" from the Crown of printing the King James or Authorized Version of Scripture at Oxford. This privilege created substantial returns over the next 250 years. Following the English Civil War , Vice-chancellor John Fell , Dean of Christ Church , Bishop of Oxford , and Secretary to the Delegates was determined to install printing presses in 1668, making it
15012-614: The rural fastnesses to sell the press's stock as well as books published by firms whose agencies were held by the press, very often including fiction and light reading. In India, the Branch depots in Bombay, Madras, and Calcutta were imposing establishments with sizable stock inventories, for the Presidencies themselves were large markets, and the educational representatives there dealt mostly with upcountry trade. In 1923, OUP established
15151-436: The scene on the drawing surface, thus aiding in the accurate rendering of perspective. Note: In the process discussed here, the "Fixing" step is mentioned. This is a step in the negative development process as well as in the chemical printing process. (Of course not required in digital printing). At this stage, all remaining light-sensitive materials are removed so that the product (film or print) can be exposed to light without
15290-602: The silver chloride, but not the dark particles. This discovery could have been used to stabilize or "fix" a camera image captured with silver chloride, but was not picked up by the earliest photography experimenters. Scheele also noted that red light did not have much effect on silver chloride, a phenomenon that would later be applied in photographic darkrooms as a method of seeing black-and-white prints without harming their development. Although Thomas Wedgwood felt inspired by Scheele's writings in general, he must have missed or forgotten these experiments; he found no method to fix
15429-596: The stereoscope. He received the first results in October 1840, but was not fully satisfied as the angle between the shots was very big. Between 1841 and 1842 Henry Collen made calotypes of statues, buildings and portraits, including a portrait of Charles Babbage shot in August 1841. Wheatstone also obtained daguerreotype stereograms from Mr. Beard in 1841 and from Hippolyte Fizeau and Antoine Claudet in 1842. None of these have yet been located. David Brewster developed
15568-407: The story "A Photographer's Day Out". Herbert Bowyer Berkeley discovered that with his own addition of sulfite , to absorb the sulfur dioxide given off by the chemical dithionite in the developer , dithionite was not required in the developing process. In 1881, he published his discovery. Berkeley's formula contained pyrogallol, sulfite, and citric acid. Ammonia was added just before use to make
15707-606: The subject. In July 2012, the UK's Serious Fraud Office found OUP's branches in Kenya and Tanzania guilty of bribery to obtain school bookselling contracts sponsored by the World Bank. Oxford was fined £1.9 million "in recognition of sums it received which were generated through unlawful conduct" and barred from applying for World Bank-financed projects for three years. In December 2023, concerns were raised that OUP had published an academic paper based on genetic data taken from
15846-440: The substance "Scotophors" when he published his findings in 1719. He thought the discovery could be applied to detect whether metals or minerals contained any silver and hoped that further experimentation by others would lead to some other useful results. Schulze's process resembled later photogram techniques and is sometimes regarded as the very first form of photography. The early science fiction novel Giphantie (1760) by
15985-425: The surface. Then through the use of a rolling press, five tons of pressure were used to flatten the grains, enabling every one of them to capture and absorb color and their microscopic size allowing the illusion that the colors are merged. The final step was adding a coat of the light-capturing substance silver bromide , after which a color image could be imprinted and developed. In order to see it, reversal processing
16124-742: The university's first central print shop. In 1674, OUP began to print a broadsheet calendar, known as the Oxford Almanack , that was produced annually without interruption from 1674 to 2019. Fell drew up the first formal programme for the university's printing, which envisaged hundreds of works, including the Bible in Greek , editions of the Coptic Gospels and works of the Church Fathers , texts in Arabic and Syriac , comprehensive editions of classical philosophy , poetry, and mathematics,
16263-531: The unsupported year 1780 was attached to it. As Arago indicated the first years of the 19th century and a date prior to the 1802 publication of Wedgwood's process, this would mean that Charles' demonstrations took place in 1800 or 1801, assuming that Arago was this accurate almost 40 years later. Nicéphore Niépce was a French aristocrat, scientist, and chemist. His family fortune allowed him to engage in inventions and scientific research. In 1816, using paper coated with silver chloride , he succeeded in photographing
16402-457: The war. Gernsheim was granted British citizenship in 1946 and continued to live in London for most of his life. Though having studied art history, Gernsheim's inclination toward a specialisation in photography history came from having been a photographer himself. In 1945, at Beaumont Newhall's prompting, Helmut and Alison Gernsheim started collecting the works of historic photographers, especially British ones, which were disappearing. They amassed
16541-528: The wings of insects". He also found that solar microscope images of small objects were easily captured on prepared paper. Davy, apparently unaware or forgetful of Scheele's discovery, concluded that substances should be found to eliminate (or deactivate) the unexposed particles in silver nitrate or silver chloride "to render the process as useful as it is elegant". Wedgwood may have prematurely abandoned his experiments because of his frail and failing health. He died at age 34 in 1805. Davy seems not to have continued
16680-407: The world. Its first book was printed in Oxford in 1478, with the Press officially granted the legal right to print books by decree in 1586. It is the second-oldest university press after Cambridge University Press , which was founded in 1534. It is a department of the University of Oxford. It is governed by a group of 15 academics, the Delegates of the Press, appointed by the vice-chancellor of
16819-465: Was 176x176 pixels with only one bit per pixel, i.e., stark black and white with no intermediate gray tones, but by combining multiple scans of the photograph done with different black-white threshold settings, grayscale information could also be acquired. OUP Oxford University Press ( OUP ) is the publishing house of the University of Oxford . It is the largest university press in
16958-574: Was about money, not prestige. Nor does the course of the litigation give any reason to suppose that the Press had any interest but to resist the claim, no matter on what grounds, so long as they succeeded." Lord Justice Leggatt added: "It is difficult to know what the Deputy Judge (Lightman) meant by a 'firm commitment' other than an intention to create legal relations. Nothing short of that would have had any value whatever for Mr Malcolm... To suggest that Mr Hardy intended to induce Mr Malcolm to revise
17097-427: Was always here, but I cannot make out what he did." By the early 20th century, OUP expanded its overseas trade, partly due to the efforts of Humphrey Milford , the publisher of the University of Oxford from 1913 to 1945. The 1920s saw skyrocketing prices of both materials and labour. Paper was hard to come by and had to be imported from South America through trading companies. Economies and markets slowly recovered as
17236-466: Was captured with a camera, but at least eight hours or even several days of exposure in the camera were required and the earliest results were very crude. Niépce's associate Louis Daguerre went on to develop the daguerreotype process, the first publicly announced and commercially viable photographic process. The daguerreotype required only minutes of exposure in the camera, and produced clear, finely detailed results. On August 2, 1839 Daguerre demonstrated
17375-468: Was darkened by sunlight. After experiments with threads that had created lines on the bottled substance after he placed it in direct sunlight for a while, he applied stencils of words to the bottle. The stencils produced copies of the text in dark red, almost violet characters on the surface of the otherwise whitish contents. The impressions persisted until they were erased by shaking the bottle or until overall exposure to light obliterated them. Schulze named
17514-416: Was given the formal title of Publisher to the university. Frowde came from the book trade, not the university, and remained an enigma to many. One obituary in Oxford's staff magazine The Clarendonian admitted, "Very few of us here in Oxford had any personal knowledge of him." Despite that, Frowde became vital to OUP's growth, adding new lines of books to the business, presiding over the massive publication of
17653-421: Was made practical by Hermann Wilhelm Vogel 's 1873 discovery of a way to make emulsions sensitive to the rest of the spectrum, gradually introduced into commercial use beginning in the mid-1880s. Two French inventors, Louis Ducos du Hauron and Charles Cros , working unknown to each other during the 1860s, famously unveiled their nearly identical ideas on the same day in 1869. Included were methods for viewing
17792-507: Was not recognized as its inventor. In 1839, John Herschel made the first glass negative, but his process was difficult to reproduce. Slovene Janez Puhar invented a process for making photographs on glass in 1841; it was recognized on June 17, 1852, in Paris by the Académie National Agricole, Manufacturière et Commerciale. In 1847, Nicephore Niépce's cousin, the chemist Niépce St. Victor , published his invention of
17931-709: Was not until 1939 that the Music Department showed its first profitable year. The Depression of 1929 dried profits from the Americas to a trickle, and India became 'the one bright spot' in an otherwise dismal picture. Bombay was the nodal point for distribution to the Africas and onward sale to Australasia, and people who trained at the three major depots later moved to pioneer branches in Africa and Southeast Asia. In 1927–1934 Oxford University Press, Inc., New York,
18070-446: Was not, in the trade, regarded as preventing a formal agreement from coming into existence. Candour would, I believe, have required that this should have been made clear to the judge and ourselves, rather than a determined refusal to let the true position come to light... This is not quite all. I do not know whether an outsider studying the history of this transaction and of this litigation would feel that, in his self-financed struggle with
18209-615: Was published in 1942 and led to his becoming a friend of the fellow critic and historian Beaumont Newhall . Gernsheim earned his release from internment by volunteering to work for the National Buildings Record , returning to London in 1942 to photograph important monuments with a view to revealing their artistic merits. These photographs became the basis of two more books. They were praised by critics including Kenneth Clark and Nikolaus Pevsner and in 1943 were described by The Architectural Review as "nothing short of
18348-596: Was reorganised by Geoffrey Cumberlege to return it to profitability from the lows of the Depression years. (In 1945–1956, Cumberlege would succeed Milford as publisher to the University of Oxford). The period following World War II saw consolidation in the face of the breakup of the Empire and the post-war reorganization of the Commonwealth. In the 1960s, OUP Southern Africa started publishing local authors for
18487-583: Was reported in a front-page article in The Oxford Times , along with OUP's response. In March 2001, after a 28-year battle with the Indian tax authorities, OUP lost its tax exemption in India. The Supreme Court ruled that OUP was not tax exempt in the subcontinent "because it does not carry out any university activities there but acts simply as a commercial publisher". To pay off back taxes, owed since
18626-479: Was sought from the very beginning. Results were demonstrated by Edmond Becquerel as early as the year of 1848, but exposures lasting for hours or days were required and the captured colors were so light-sensitive they would only bear very brief inspection in dim light. The first color photograph was a set of three black-and-white photographs taken through red, green, and blue color filters and shown superimposed by using three projectors with similar filters. It
18765-501: Was still a joint-stock printing business in an academic backwater, offering learned works to a relatively small readership of scholars and clerics At this time, Thomas Combe joined the press and became the university's Printer until he died in 1872. Combe was a better businessman than most Delegates but still no innovator: he failed to grasp the huge commercial potential of India paper , which grew into one of Oxford's most profitable trade secrets in later years. Even so, Combe earned
18904-470: Was taken by Thomas Sutton in 1861 for use in a lecture by the Scottish physicist James Clerk Maxwell , who had proposed the method in 1855. The photographic emulsions then in use were insensitive to most of the spectrum , so the result was very imperfect and the demonstration was soon forgotten. Maxwell's method is now most widely known through the early 20th century work of Sergei Prokudin-Gorskii . It
19043-548: Was the first step in the path that Walter Benjamin described in The Work of Art in the Age of Mechanical Reproduction . A physiognotrace is an instrument, designed to support semi-automated portrait. It was invented in the 18th century and was abandoned when light-sensitive materials were discovered. It was popular for several decades. The sitter sat in a wooden frame and turned to the side to pose. A pantograph connected to
19182-457: Was the first to write a description of using the camera obscura as a drawing aid in his popular and influential books. Della Porta's proposal was widely adopted by artists and since the 17th century portable versions of the camera obscura were commonly used—first as a tent, later as boxes. The box type camera obscura was the basis for photographic cameras, as used in the earliest attempts to capture natural images in light sensitive materials. This
19321-422: Was used to develop each plate into a transparent positive that could be viewed directly or projected with an ordinary projector. One of the drawbacks of the technology was an exposure time of at least a second in bright daylight, with the time required quickly increasing in poor light. An indoor portrait required several minutes with the subject stationary. This was because the grains absorbed color fairly slowly, and
