Who invented photography?
History of photography
In the mid-1820s, Nicéphore Niépce first managed to fix an image that 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. The details were introduced as a gift to the world in 1839, a date generally accepted as the birth year of practical photography.
The metal-based daguerreotype process soon had some competition from the paper-based calotype negative and salt print processes invented by William Henry Fox Talbot. 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, including roll films for casual use by amateurs. In the mid-20th century, developments made it possible for amateurs to take pictures in natural color as well as in black-and-white.
Helmut Gernsheim
In 1945, at Newhall's prompting, Helmut and Alison Gernsheim started collecting the works of historic photographers, especially British ones, which were disappearing. They amassed a huge collection containing work by such luminaries as 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 Helmut 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 the 180,000-word book "The History of Photography". When the first edition was published by the OUP in 1955 it became an instant classic and the definitive reference work for historians of photography for decades afterwards, being described by Beaumont Newhall as "a milestone in the history of photography" and by other reviewers as "the photographer's bible" and "an encyclopaedic work". Along the way, in 1952 Gernsheim discovered the long-lost world's first permanent photograph from nature, created by Joseph Nicéphore Niépce in 1826 ("View from the Window at Le Gras"). Helmut and Alison continued to publish numerous articles and books on various aspects of photography and a variety of photographers.
Charles Leander Weed
Charles Leander Weed was an American photographer, who was born in New York state in 1824, and died in 1903. He is perhaps best known for being one of the earliest photographers, if not the first photographer, to enter and photograph what is now Yosemite National Park.
Camera
The word "camera" comes from "camera obscura", which means "dark chamber" and is the Latin name of the original device for projecting an image of external reality onto a flat surface. The modern photographic camera evolved from the camera obscura. The functioning of the camera is very similar to the functioning of the human eye. The first permanent photograph was made in 1825 by Joseph Nicéphore Niépce.
Wedding photography
Like the technology of photography itself, the practice of wedding photography has evolved and grown since the invention of the photographic art form in 1826 by Joseph Nicéphore Niépce. In fact, an early photograph, recorded some 14 years after the fact, may be a recreation for the camera of the 1840 wedding of Queen Victoria to Prince Albert. However, in the early days of photography, most couples of more humble means did not hire a photographer to record the actual wedding itself. Until the later half of the 19th century, most people didn’t pose for formal wedding photos during the wedding. Rather, they might pose for a formal photo in their best clothes before or after a wedding. In the late 1860s, more couples started posing in their wedding clothes or sometimes hired a photographer to come to the wedding venue. "(See the gallery at White wedding.)"
Due to the nature of the bulky equipment and lighting issues, wedding photography was largely a studio practice for most of the late 19th century. Over time, technology improved, but many couples still might only pose for a single wedding portrait. Wedding albums started becoming more commonplace towards the 1880s, and the photographer would sometimes include the wedding party in the photographs. Often the wedding gifts would be laid out and recorded in the photographs as well.
Photography in the United States
In spring 1839, the daguerreotype was introduced into the United States by an Englishman named D.W. Seager, who took the first photograph of a view of St. Paul’s Church and a corner of the Astor House in Lower Manhattan in New York City. Painter and inventor Samuel Finley Breese Morse had met Louis Daguerre in Paris in the spring of 1839, becoming the first American to see his photographic process and becoming enamored with it as a result. When he returned to the United States later that year, he enthusiastically promoted the daguerreotype while hailing Seager's prototypical image. Morse had painted "The Gallery of the Louvre" in 1833, and the appeal of the medium of the daguerreotype was an obvious one to him: it was a means of making faithful copies of artworks, in addition to anything else that would be still in front of the slow eye of the camera.
Vilém Flusser
Writing about photography in the 1970s and 80s, in the face of the early worldwide impact of computer technologies, Flusser argued that the photograph was the first in a number of technical image forms to have fundamentally changed the way in which the world is seen. Historically, the importance of photography had been that it introduced nothing less than a new epoch: 'The invention of photography constitutes a break in history that can only be understood in comparison to that other historical break constituted by the invention of linear writing.'
Thomas Sutton (photographer)
Thomas Sutton (1819 – 19 March 1875, in Pwllheli or more likely Kensington) was an English photographer, author, and inventor.
Manuel Arruda da Câmara
(added by HJ Arruda Pacheco July 28, 2017) I am a little confused. How can there exist a picture of my ancestor as photography was invented after Manuel Arruda da Camara's death. First known photo was around 1825.
Camera obscura
The earliest use of the term "camera obscura" is found in the 1604 book "Ad Vitellionem Paralipomena" by German mathematician, astronomer, and astrologer Johannes Kepler. Kepler discovered the working of the camera obscura by recreating its principle with a book replacing a shining body and sending threads from its edges through a many-cornered aperture in a table onto the floor where the threads recreated the shape of the book. He also realized that images are "painted" inverted and reversed on the retina of the eye and figured that this is somehow corrected by the brain. 
In 1607 Kepler studied the sun in his camera obscura and noticed a sunspot, but he thought it was Mercury transiting the sun.
In his 1611 book "Dioptrice" Kepler described how the projected image of the camera obscura can be improved and reverted with a lens. It is believed he later used a telescope with three lenses to revert the image in the camera obscura.
William Taylor (inventor)
William Taylor (11 June 1865 – February 28, 1937) was a British inventor noted for his many inventions for improvement of photographic lenses.
Pigeon photography
Pigeon photography is an aerial photography technique invented in 1907 by the German apothecary Julius Neubronner, who also used pigeons to deliver medications. A homing pigeon was fitted with an aluminium breast harness to which a lightweight time-delayed miniature camera could be attached. Neubronner's German patent application was initially rejected, but was granted in December 1908 after he produced authenticated photographs taken by his pigeons. He publicized the technique at the 1909 Dresden International Photographic Exhibition, and sold some images as postcards at the Frankfurt International Aviation Exhibition and at the 1910 and 1911 Paris Air Shows.
Digital imaging
In 1826 Niepce was the first to develop a photo which used lights to reproduce images, the advancement of photography has drastically increased over the years. Everyone is now a photographer in their own way, whereas during the early 1800s and 1900s the expense of lasting photos was highly valued and appreciated by consumers and producers. According to the magazine article on five ways digital camera changed us states the following:The impact on professional photographers has been dramatic. Once upon a time a photographer wouldn’t dare waste a shot unless they were virtually certain it would work.”The use of digital imaging( photography) has changed the way we interacted with our environment over the years. Part of the world is experienced differently through visual imagining of lasting memories, it has become a new form of communication with friends, family and love ones around the world without face to face interactions. Through photography it is easy to see those that you have never seen before and feel their presence without them being around, for example Instagram is a form of social media where anyone is allowed to shoot, edit, and share photos of whatever they want with friends and family. Facebook, snapshot, vine and twitter are also ways people express themselves with little or no words and are able to capture every moment that is important. Lasting memories that were hard to capture, is now easy because everyone is now able to take pictures and edit it on their phones or laptops. Photography has become a new way to communicate and it is rapidly increasing as time goes by, which has affected the world around us.
Hippolyte Bayard
Bayard was persuaded to postpone announcing his process to the French Academy of Sciences by François Arago, a friend of Louis Daguerre, who invented the rival daguerreotype process. Arago's conflict of interest cost Bayard the recognition as one of the principal inventors of photography. He eventually gave details of the process to the French Academy of Sciences on 24 February 1840 in return for money to buy better equipment.
Camera
The first permanent photograph of a camera image was made in 1825 by Joseph Nicéphore Niépce using a sliding wooden box camera made by Charles and Vincent Chevalier in Paris. Niépce had been experimenting with ways to fix the images of a camera obscura since 1816. The photograph Niépce succeeded in creating shows the view from his window. It was made using an 8-hour exposure on pewter coated with bitumen. Niépce called his process "heliography". Niépce corresponded with the inventor Louis-Jacques-Mande Daguerre, and the pair entered into a partnership to improve the heliographic process. Niépce had experimented further with other chemicals, to improve contrast in his heliographs. Daguerre contributed an improved camera obscura design, but the partnership ended when Niépce died in 1833. Daguerre succeeded in developing a high-contrast and extremely sharp image by exposing on a plate coated with silver iodide, and exposing this plate again to mercury vapor. By 1837, he was able to fix the images with a common salt solution. He called this process "Daguerreotype", and tried unsuccessfully for a couple years to commercialize it. Eventually, with help of the scientist and politician François Arago, the French government acquired Daguerre's process for public release. In exchange, pensions were provided to Daguerre as well as Niépce's son, Isidore.
Digital photography
The real history of digital photography as we know it began in the 1950s. In 1951, the first digital signals were saved to magnetic tape via the first video tape recorder. Six years later, in 1957, the first digital image was produced through a computer by Russell Kirsch. It was an image of his son. In the late 1960s, Willard S. Boyle and George E. Smith, two physicists with Bell Labs, Inc., invented the charge-coupled device (CCD), a semiconductor circuit later used in the first digital video cameras for television broadcasting. Their invention was recognized by a Nobel Prize in Physics in 2009. The first published color digital photograph was produced in 1972 by Michael Francis Tompsett using CCD sensor technology and was featured on the cover of "Electronics Magazine". It was a picture of his wife, Margaret Thompsett.
The Cromemco Cyclops, a digital camera developed as a commercial product and interfaced to a microcomputer, was featured in the February 1975 issue of "Popular Electronics" magazine. It used metal-oxide semiconductor (MOS) technology for its image sensor.
Micrograph
The microscope has been mainly used for scientific discovery. It has also been linked to the arts since its invention in the 17th century. Early adopters of the microscope, such as Robert Hooke and Antonie van Leeuwenhoek, were excellent illustrators. After the invention of photography in the 1820s the microscope was later combined with the camera to take pictures instead of relying on an artistic rendering.
History of photography
French balloonist/professor/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 documenting 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 the unsupported year 1780 was attached to it. Since Arago indicated the first years of the 19th century and a date prior to Wedgwood's process published in 1802, this would mean that Charles' demonstrations took place in 1800 or 1801 - assuming Arago was this accurate almost 40 years later.
Fred Spira
Fred Spira (1924–2007) was an inventor and innovator in photography as well as a collector of photographic equipment, images, books, and ephemera. He is credited as one of three individuals who opened up the U.S. market to quality Japanese photographic goods.
Edward Weston
Edward Henry Weston (March 24, 1886 – January 1, 1958) was a 20th-century American photographer. He has been called "one of the most innovative and influential American photographers…" and "one of the masters of 20th century photography." Over the course of his 40-year career Weston photographed an increasingly expansive set of subjects, including landscapes, still lives, nudes, portraits, genre scenes and even whimsical parodies. It is said that he developed a "quintessentially American, and specially Californian, approach to modern photography" because of his focus on the people and places of the American West. In 1937 Weston was the first photographer to receive a Guggenheim Fellowship, and over the next two years he produced nearly 1,400 negatives using his 8 × 10 view camera. Some of his most famous photographs were taken of the trees and rocks at Point Lobos, California, near where he lived for many years.
Henri Cartier-Bresson
Henri Cartier-Bresson (; August 22, 1908 – August 3, 2004) was a French humanist photographer considered a master of candid photography, and an early user of 35 mm film. He pioneered the genre of street photography, and viewed photography as capturing a "decisive moment."
Astrophotography
The first-known attempt at astronomical photography was by Louis Jacques Mandé Daguerre, inventor of the daguerreotype process which bears his name, who attempted in 1839 to photograph the Moon. Tracking errors in guiding the telescope during the long exposure meant the photograph came out as an indistinct fuzzy spot. John William Draper, New York University Professor of Chemistry, physician and scientific experimenter managed to make the first successful photograph of the moon a year later on March 23, 1840, taking a 20-minute-long daguerreotype image using a reflecting telescope.
William Willis (inventor)
William Willis Jr. (1841–1923) is a British inventor who developed the platinum printing process, an early form of photography, based on the light sensitivity of platinum salts, originally discovered by John Herschel.
History of photography
In 1851 Frederick Scott Archer invented the collodion process. Photographer and children's author Lewis Carroll used this process. (Carroll refers to the process as "Tablotype" in the story "A Photographer's Day Out")
Camera obscura
Dutch inventor Cornelis Drebbel is thought to have constructed a box-type camera obscura which corrected the inversion of the projected image. In 1622 he sold one to the Dutch poet, composer and diplomat Constantijn Huygens who used it to paint and recommended it to his artist friends. Huygens wrote to his parents (translated from French):
German Orientalist, mathematician, inventor, poet, and librarian Daniel Schwenter wrote in his 1636 book "Deliciae Physico-Mathematicae" about an instrument that a man from Pappenheim had shown him, which enabled movement of a lens to project more from a scene through the camera obscura. It consisted of a ball as big as a fist, through which a hole (AB) was made with a lens attached on one side (B). This ball was placed inside two halves of part of a hollow ball that were then glued together (CD), in which it could be turned around. This device was attached to a wall of the camera obscura (EF). This universal joint mechanism was later called a scioptric ball.
Alfred Maul
Although people had long been experimenting with rockets, hardly anyone had used them in a practical application. It was Alfred Maul, an industrialist and engineer born in Pößneck, in the Duchy of Saxe-Meiningen, that thought of, and implemented, the idea of taking photographs of the land with a rocket-attached camera. He was inspired by Ludwig Rahrmann, who in 1891 patented a means of attaching a camera to a large calibre artillery projectile or rocket. Previously, aerial photographs had been taken from balloons and kites, and in 1896 or 1897 by Alfred Nobel's rocket, from a small rocket at 100 metres altitude. In 1903 Julius Neubronner's pigeons were used to take aerial photos but found to be too unreliable.
John Myers (photographer)
In 1976 Myers self-published a book and co-curated an exhibition of photographs by Harold Eugene Edgerton (1903–1990). Edgerton was the inventor of single and multi-flash stroboscopic photography and this was the first solo exhibition in Europe of his work.
History of photography
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 Nationale Agricole, Manufacturière et Commerciale. In 1847, Nicephore Niépce's cousin, the chemist Niépce St. Victor, published his invention of 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.
Semyon Davidovich Kirlian
Semyon Davidovich Kirlian (; ; ; 20 February 1898 – 4 April 1978) was a Soviet inventor and researcher of Armenian descent, who along with his wife Valentina Khrisanovna Kirlian (; died 1972), a teacher and journalist, discovered and developed Kirlian photography.
John Johnson (inventor)
Wolcott then made a camera that day with improvements on Daguerre's method. The camera was a wooden box 15 inches long, 8.5 inches high, and 8 inches wide. There was a 7-inch concave mirror in the back of the camera. The camera was constructed so that it had a large opening in front where the light rays of the person of the portrait passed through an aperture. The photo-sensitive 2 inch exposure plate was in a detachable frame in the center of this aperture opening, just inside the box. The operator of the camera would set up the focusing of the portrait picture on an unsensitized plate first. Then once the camera was focused with all of the mechanical items involved, then the camera operator would replace the focusing plate with the sensitized plate to take the picture.
Photography historians Dr. Robert Taft and Patrick Robertson stated that Wolcott took a picture of Johnson as the first portrait in the world on October 7, 1839. On March 4, 1840, they opened the first studio in the world as a commercial enterprise for taking pictures of people. The customer would sit for their likeness to be captured on a permanent medium for future viewing. The commercial photography studio was located in New York City at Broadway and Chamber Street. Johnson with Wolcott created the world's first photography portrait studio as a business. They opened their commercial daguerreotype photography portrait studio in March 1840.
Photogravure
The earliest forms of photogravure were developed by two original pioneers of photography itself, first Nicéphore Niépce in France in the 1820s, and later Henry Fox Talbot in England. Niépce was seeking a means to create photographic images on plates that could then be etched and used to make prints on paper with a traditional printing press. Niépce's early images were among the first photographs, pre-dating daguerreotypes and the later wet collodion photographic process. Talbot, inventor of the calotype paper negative process, wanted to make paper prints that would not fade. He worked on his photomechanical process in the 1850s and patented it in 1852 ('photographic engraving') and 1858 ('photoglyphic engraving').
Chronophotography
Photography is an art and science which was invented and developed beginning in the 1830s. Initially, it was used as a documentation device – for portraiture, historical moments, battles in war, and so on. With how rapidly the technological and artistic world began to develop, new uses and ideas for the camera also began to develop. With the invention of the camera, art no longer necessarily had to capture life. The camera became the dominant source of accurate depiction of life. As the technology became more sophisticated, so did the activities for which people needed cameras.
Color photography
Colour photography was attempted beginning in the 1840s. Early experiments were directed at finding a "chameleon substance" which would assume the colour of the light falling on it. Some encouraging early results, typically obtained by projecting a solar spectrum directly onto the sensitive surface, seemed to promise eventual success, but the comparatively dim image formed in a camera required exposures lasting for hours or even days. The quality and range of the colour was sometimes severely limited mainly to primary colours, as in the chemically complicated "Hillotype" process invented by American daguerreotypist Levi Hill around 1850. Other experimenters, such as Edmond Becquerel, achieved better results but could find no way to prevent the colours from quickly fading when the images were exposed to light for viewing. Over the following several decades, renewed experiments along these lines periodically raised hopes and then dashed them, yielding nothing of practical value.
Voigtländer
From 1839, the year, when the invention of photography was being published, came objective optics and from 1840 complete cameras for photography. The Voigtländer objectives were revolutionary because they were the first mathematically calculated precision objectives in the history of photography, developed by the German-Hungarian mathematics professor Josef Maximilian Petzval, with technical advice provided by Peter Voigtländer. Voigtländer went on to produce the first Petzval portrait photographic lens (the fastest lens at that time: f/3.6) in 1840, and the world's first all-metal daguerreotype camera ("Ganzmetallkamera") in 1840, also bringing out photographic plate cameras shortly afterwards. An original of the 1840 all-metal daguerreotype camera with "No. 84 Voigtländer & Sohn in Vienna" is exhibited in the "Deutsches Museum" in Munich.
Louis Le Prince
At the start of 1890, the Edison workers had begun experimenting with using a strip of celluloid film to capture moving images. The first public results of these experiments were shown in May 1891. But Le Prince's widow and son, Adolphe, were keen to advance Louis' cause as the inventor of cinematography. In 1898 Adolphe appeared as a witness for the defence in a court case brought by Edison against the American Mutoscope Company. This suit claimed that Edison was the first and sole inventor of cinematography, and thus entitled to royalties for the use of the process. Adolphe Le Prince was not allowed to present his father's two cameras as evidence (and so establish Le Prince's prior claim as inventor) and eventually the court ruled in favour of Edison. However, a year later that ruling was overturned.
Johann Pucher
Johann Augustin Pucher ( or "Ivan Pucher"; 26 August 1814 – 7 August 1864) was a Slovene priest, scientist, photographer, artist, and poet who invented an unusual process for making photographs on glass.
Paul Claude-Michel Carpentier
Carpentier was a friend of Louis-Jacques-Mandé Daguerre (1787–1851) and in 1855 he wrote "Notice sur Daguerre", which is a first hand account of the invention of photography and the diorama.
Photorealism
The invention of photography in the nineteenth century had three effects on art: portrait and scenic artists were deemed inferior to the photograph and many turned to photography as careers; within nineteenth- and twentieth-century art movements it is well documented that artists used the photograph as source material and as an aid—however, they went to great lengths to deny the fact fearing that their work would be misunderstood as imitations; and through the photograph's invention artists were open to a great deal of new experimentation. Thus, the culmination of the invention of the photograph was a break in art's history towards the challenge facing the artist—since the earliest known cave drawings—trying to replicate the scenes they viewed.
Camera
Before the development of the photographic camera, it had been known for hundreds of years that some substances, such as silver salts, darkened when exposed to sunlight. In a series of experiments, published in 1727, the German scientist Johann Heinrich Schulze demonstrated that the darkening of the salts was due to light alone, and not influenced by heat or exposure to air. The Swedish chemist Carl Wilhelm Scheele showed in 1777 that silver chloride was especially susceptible to darkening from light exposure, and that once darkened, it becomes insoluble in an ammonia solution. The first person to use this chemistry to create images was Thomas Wedgwood. To create images, Wedgwood placed items, such as leaves and insect wings, on ceramic pots coated with silver nitrate, and exposed the set-up to light. These images weren't permanent, however, as Wedgwood didn't employ a fixing mechanism. He ultimately failed at his goal of using the process to create fixed images created by a camera obscura.
Photography
Photography is the result of combining several technical discoveries, relating to seeing an image and capturing the image. The discovery of the camera obscura ("dark chamber" in Latin) that provides an image of a scene dates back to ancient China. Greek mathematicians Aristotle and Euclid independently described a pinhole camera in the 5th and 4th centuries BCE. In the 6th century CE, Byzantine mathematician Anthemius of Tralles used a type of camera obscura in his experiments. The Arab physicist Ibn al-Haytham (Alhazen) (965–1040) also invented a camera obscura and pinhole camera.
Hippolyte Bayard
Hippolyte Bayard (20 January 1801 – 14 May 1887) was a French photographer and pioneer in the history of photography. He invented his own process that produced direct positive paper prints in the camera and presented the world's first public exhibition of photographs on 24 June 1839. He claimed to have invented photography earlier than Louis-Jacques Mandé Daguerre in France and William Henry Fox Talbot in England, the men traditionally credited with its invention.
Pictorialism
Photography as a technical process involving the development of film and prints in a darkroom originated in the early 19th century, with the forerunners of traditional photographic prints coming into prominence around 1838 to 1840. Not long after the new medium was established, photographers, painters and others began to argue about the relationship between the scientific and artistic aspects of the medium. As early as 1853, English painter William John Newton proposed that the camera could produce artistic results if the photographer would keep an image slightly out of focus. Others vehemently believed that a photograph was equivalent to the visual record of a chemistry experiment. Photography historian Naomi Rosenblum points out that "the dual character of the medium—its capacity to produce both art and document—[was] demonstrated soon after its discovery ... Nevertheless, a good part of the nineteenth century was spent debating which of these directions was the medium's true function."
T. M. Schleier
Theodore M. Schleier (April 20, 1832 – December 13, 1908) was a Prussian-born American photographer, inventor, and diplomat, active primarily in the southeastern United States in the latter half of the 19th century. While operating from a studio in Nashville, Tennessee, he helped document life in the city during the Civil War. He later moved to Knoxville, Tennessee, where he captured some of the city's earliest photographs. His inventions include an early artificial lighting system for photography studios.
History of photography
The coining of the word "photography" is usually attributed to Sir John Herschel in 1839. It is based on the Greek "φῶς (phōs)", (genitive: "phōtós") meaning "light", and "γραφή (graphê)", meaning "drawing, writing", together meaning "drawing with light".
Edwin H. Land
Edwin Herbert Land, ForMemRS, FRPS, Hon.MRI (May 7, 1909 – March 1, 1991) was an American scientist and inventor, best known as the co-founder of the Polaroid Corporation. He invented inexpensive filters for polarizing light, a practical system of in-camera instant photography, and the retinex theory of color vision, among other things. His Polaroid instant camera went on sale in late 1948 and made it possible for a picture to be taken and developed in 60 seconds or less.
History of forensic photography
French photographer, Alphonse Bertillon was the first to realize that photographs were futile for identification if they were not standardized by using the same lighting, scale and angles. He wanted to replace traditional photographic documentation of criminals with a system that would guarantee reliable identification. He suggested anthropological studies of profiles and full-face shots to identify criminals. He published La Photographie Judiciaire (1890), which contained rules for a scientifically exact form of identification photography. He stated that the subjects should be well lit, photographed full face and also in profile, with the ear visible. Bertillon maintained that the precepts of commercial portraits should be forgotten in this type of photography. By the turn of the century, both his measurement system and photographic rules had been accepted and introduced in almost all states. Thus, Bertillon is credited with the invention of the mug shot.
Photography
Several people may have coined the same new term from these roots independently. Hercules Florence, a French painter and inventor living in Campinas, Brazil, used the French form of the word, "photographie", in private notes which a Brazilian historian believes were written in 1834. This claim is widely reported but apparently has never been independently confirmed as beyond reasonable doubt.
Nicéphore Niépce
Joseph Nicéphore Niépce (; 7 March 1765 – 5 July 1833) was a French inventor, usually credited as the inventor of photography and a pioneer in that field. Niépce developed heliography, a technique he used to create the world's oldest surviving product of a photographic process: a print made from a photoengraved printing plate in 1825. In 1826 or 1827, he used a primitive camera to produce the oldest surviving photograph of a real-world scene. Among Niépce's other inventions was the Pyréolophore, the world's first internal combustion engine, which he conceived, created, and developed with his older brother Claude.
History of photography
A natural phenomenon, known as camera obscura or pinhole image, can project a (reversed) image through 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 Chinese writings called Mozi, dated to the 4th century BCE. Until the 16th century 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 advised using the camera obscura as a drawing aid in his popular and influential books. Della Porta's advice 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 the earliest photographic cameras when photography was developed in the early 19th century.
The notion that light can affect various substances - for instance the suntanning of skin or fading of textile - must have been around since very early times. Ideas of fixing the image seen in mirrors or other ways of creating images automatically may also have been in people's mind long before anything like photography was developed. However, there seem to be no historical records of any ideas even remotely resembling photography before 1725, despite early knowledge of light-sensitive materials and the camera obscura.
It has been suggested that some lost type of photographic technology must have been applied before 1357: the Shroud of Turin contains an image that resembles a sepia photographic negative and is much clearer when it is converted to a positive image. The actual method that resulted in this image has not yet been conclusively identified. It first appeared in historical records in 1357 and radiocarbon dating tests indicate it was probably made between 1260 and 1390. No other examples of detailed negative images from before the 19th century are known.
Photography
The first permanent photoetching was an image produced in 1822 by the French inventor Nicéphore Niépce, but it was destroyed in a later attempt to make prints from it. Niépce was successful again in 1825. In 1826 or 1827, he made the "View from the Window at Le Gras", the earliest surviving photograph from nature (i.e., of the image of a real-world scene, as formed in a camera obscura by a lens).
Photography
Around the year 1800, British inventor Thomas Wedgwood made the first known attempt to capture the image in a camera obscura by means of a light-sensitive substance. He used paper or white leather treated with silver nitrate. Although he succeeded in capturing the shadows of objects placed on the surface in direct sunlight, and even made shadow copies of paintings on glass, it was reported in 1802 that "the images formed by means of a camera obscura have been found too faint to produce, in any moderate time, an effect upon the nitrate of silver." The shadow images eventually darkened all over.
History of the camera
The forerunner to the photographic camera was the "camera obscura". Camera obscura (Latin for "dark room") is the natural optical phenomenon that occurs when an image of a scene at the other side of a screen (or for instance a wall) is projected through a small hole in that screen and forms an inverted image (left to right and upside down) on a surface opposite to the opening. The oldest known record of this principle is a description by Han Chinese philosopher Mozi (ca. 470 to ca. 391 BC). Mozi correctly asserted that the camera obscura image is inverted because light travels in straight lines from its source. In the 11th century Arab physicist Ibn al-Haytham (Alhazen)'s wrote very influential books about optics, including experiments with light through a small opening in a darkened room.
Photograph
After Niépce's death in 1833, Daguerre concentrated on silver halide-based alternatives. He exposed a silver-plated copper sheet to iodine vapor, creating a layer of light-sensitive silver iodide; exposed it in the camera for a few minutes; developed the resulting invisible latent image to visibility with mercury fumes; then bathed the plate in a hot salt solution to remove the remaining silver iodide, making the results light-fast. He named this first practical process for making photographs with a camera the daguerreotype, after himself. Its existence was announced to the world on 7 January 1839 but working details were not made public until 19 August. Other inventors soon made improvements which reduced the required exposure time from a few minutes to a few seconds, making portrait photography truly practical and widely popular.
Valentin Wolfenstein
Valentin Wolfenstein (19 April 1845 – 3 February 1909) was a Swedish-American photographer who worked both in Stockholm and Los Angeles, California. He was one of the first photographers to use flash-lamps for photography.
Panoramic photography
The device of the panorama existed in painting, particularly in murals as early as 20 A.D. in those found in Pompeii, as a means of generating an immersive 'panoptic' experience of a vista, long before the advent of photography. In the century prior to the advent of photography, and from 1787, with the work of Robert Barker, it reached a pinnacle of development in which whole buildings were constructed to house 360° panoramas, and even incorporated lighting effects and moving elements. Indeed, the careers of one of the inventors of photography, Daguerre, began in the production of popular panoramas and dioramas.
Warren De la Rue
Warren De la Rue (15 January 181519 April 1889) was a British astronomer, chemist, and inventor, most famous for his pioneering work in astronomical photography.
François Arago
In 1830, Arago, who always professed liberal opinions of the republican type, was elected a member of the chamber of deputies for the Pyrénées-Orientales "département", and he employed his talents of eloquence and scientific knowledge in all questions connected with public education, the rewards of inventors, and the encouragement of the mechanical and practical sciences. Many of the most creditable national enterprises, dating from this period, are due to his advocacy – such as the reward to Louis-Jacques Daguerre for the invention of photography, the grant for the publication of the works of Fermat and Laplace, the acquisition of the museum of Cluny, the development of railways and electric telegraphs, the improvement of the reneile. In 1839, Arago reported the invention of photography to stunned listeners by displaying the first photo taken of Egypt, Ras El Tin Palace.
Louis Daguerre
Louis-Jacques-Mandé Daguerre (; ; 18 November 1787 – 10 July 1851), better known as Louis Daguerre, was a French artist and photographer, recognized for his invention of the daguerreotype process of photography. He became known as one of the fathers of photography. Though he is most famous for his contributions to photography, he was also an accomplished painter and a developer of the diorama theatre.
Saint-Loup-de-Varennes
Nicéphore Niépce, the inventor of photography, lived in Saint-Loup-de-Varennes, where he died in 1833.
Most or all of his photographs, including one taken in 1827 and now the oldest known surviving camera photograph, were made at Le Gras, his ancestral family estate in this village.
Panoramic photography
The development of panoramic cameras was a logical extension of the nineteenth-century fad for the panorama. One of the first recorded patents for a panoramic camera was submitted by Joseph Puchberger in Austria in 1843 for a hand-cranked, 150° field of view, 8-inch focal length camera that exposed a relatively large Daguerreotype, up to long. A more successful and technically superior panoramic camera was assembled the next year by Friedrich von Martens in Germany in 1844. His camera, the Megaskop, used curved plates and added the crucial feature of set gears, offering a relatively steady panning speed. As a result, the camera properly exposed the photographic plate, avoiding unsteady speeds that can create an unevenness in exposure, called "banding". Martens was employed by Lerebours, a photographer/publisher. It is also possible that Martens camera was perfected before Puchberger patented his camera. Because of the high cost of materials and the technical difficulty of properly exposing the plates, Daguerreotype panoramas, especially those pieced together from several plates (see below) are rare.
After the advent of wet-plate collodion process, photographers would take anywhere from two to a dozen of the ensuing albumen prints and piece them together to form a panoramic image ("see: Segmented"). This photographic process was technically easier and far less expensive than Daguerreotypes. Some of the most famous early panoramas were assembled this way by George N. Barnard, a photographer for the Union Army in the American Civil War in the 1860s. His work provided vast overviews of fortifications and terrain, much valued by engineers, generals, and artists alike. ("see Photography and photographers of the American Civil War")
John Ernest Williamson
John Ernest Williamson (8 December 1881 – 15 July 1966) invented the "photosphere" from which he filmed and photographed undersea. He is credited as being the first person to take an underwater photograph from a submarine.
History of photography
The charge-coupled device (CCD) is the image-capturing optoelectronic component in first-generation digital cameras. It was invented in 1969 by Willard Boyle and George E. Smith at AT&T Bell Labs as a memory device. The lab was working on the Picturephone and on the development of semiconductor bubble memory. Merging these two initiatives, Boyle and Smith conceived of the design of what they termed "Charge 'Bubble' Devices". The essence of the design was the ability to transfer charge along the surface of a semiconductor. It was Dr. Michael Tompsett from Bell Labs however, who discovered that the CCD could be used as an imaging sensor. The CCD has increasingly been replaced by the active pixel sensor (APS), commonly used in cell phone cameras. These mobile phone cameras are used by billions of people worldwide, dramatically increasing photographic activity and material and also fueling citizen journalism.The web has been a popular medium for storing and sharing photos ever since the first photograph was published on the web by Tim Berners-Lee in 1992 (an image of the CERN house band Les Horribles Cernettes). Since then sites and apps such as Facebook, Flickr, Instagram, Picasa (discontinued in 2016), Imgur and Photobucket have been used by many millions of people to share their pictures.
Carlo Ponti (photographer)
Carlo Ponti was born in Ticino. He was optician to King Victor Emanuel II of Italy and inventor of megalethoscope, a viewing device for photographs and its larger version the alethoscope.
Jacob Riis
Riis had for some time been wondering how to show the squalor of which he wrote more vividly than his words could express. He tried sketching, but was incompetent at this. Camera lenses of the 1880s were slow as was the emulsion of photographic plates; photography thus did not seem to be of any use for reporting about conditions of life in dark interiors. In early 1887, however, Riis was startled to read that "a way had been discovered to take pictures by flashlight. The darkest corner might be photographed that way." The German innovation, by Adolf Miethe and Johannes Gaedicke, flash powder was a mixture of magnesium with potassium chlorate and some antimony sulfide for added stability; the powder was used in a pistol-like device that fired cartridges. This was the introduction of flash photography.
Photography
The birth of photography was then concerned with inventing means to capture and keep the image produced by the camera obscura. Albertus Magnus (1193–1280) discovered silver nitrate, and Georg Fabricius (1516–1571) discovered silver chloride, and the techniques described in Ibn al-Haytham's Book of Optics are capable of producing primitive photographs using medieval materials.
History of photography
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 Ducos du Hauron's ideas: instead of taking three separate photographs through color filters, take one through 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.
View from the Window at Le Gras
After the pioneering photographic processes of Louis Daguerre and Henry Fox Talbot were publicly announced in January 1839, Bauer championed Niépce's right to be acknowledged as the first inventor of a process for making permanent photographs. On March 9, 1839, the specimens were finally exhibited at the Royal Society. After Bauer's death in 1840 they passed through several hands and were occasionally exhibited as historical curiosities. "View from the Window at Le Gras" was last publicly shown in 1905 and then fell into oblivion for nearly fifty years.
Aerial photography
Aerial photography was first practiced by the French photographer and balloonist Gaspard-Félix Tournachon, known as "Nadar", in 1858 over Paris, France. However, the photographs he produced no longer exist and therefore the earliest surviving aerial photograph is titled 'Boston, as the Eagle and the Wild Goose See It.' Taken by James Wallace Black and Samuel Archer King on October 13, 1860, it depicts Boston from a height of 630m.
Kite aerial photography was pioneered by British meteorologist E.D. Archibald in 1882. He used an explosive charge on a timer to take photographs from the air. Frenchman Arthur Batut began using kites for photography in 1888, and wrote a book on his methods in 1890. Samuel Franklin Cody developed his advanced 'Man-lifter War Kite' and succeeded in interesting the British War Office with its capabilities.
John Johnson (inventor)
Wolcott's camera technology was taken to London by Johnson's father, William S. Johnson, in February 1840. A European franchise financial arrangement was worked out by W. S. Johnson with Richard Beard, a coal merchant and entrepreneur. They hired John Frederick Goddard, a chemist and lecturer in optics. Goddard came up a chemistry formula to make the image plate sensitive to light so that an image would develop on it much faster than the daguerreotype cameras of the time. The image plate used iodine chloride to make the plates sensitive to light, which helped to shorten the camera exposure time. The concave mirror reflector improvement and the photo-sensitive plate were the key innovative features Wolcott based his 1840 camera invention on that made portraits a possibility. This made exposure time to as low as a few minutes in bright sunlight, and since a person could be still for that long it make portraits possible using this state-of-the-art photography. Beard then opened the first public portrait studio of Europe in London in March 1841, the Daguerrean gallery at the Polytechnic Institute. Beard developed franchises of portrait studios throughout England.
History of photography
In 1816 Nicéphore Niépce, using paper coated with silver chloride, succeeded in photographing 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.
Photophone
The photophone is a telecommunications device that allows transmission of speech on a beam of light. It was invented jointly by Alexander Graham Bell and his assistant Charles Sumner Tainter on February 19, 1880, at Bell's laboratory at 1325 L Street in Washington, D.C. Both were later to become full associates in the Volta Laboratory Association, created and financed by Bell.
Alexander S. Wolcott
Alexander Simon Wolcott (also Alexander S. Wolcott and A. S. Wolcott; June 14, 1804 – March 26, 1844) was a maker of medical supplies. He was a nineteenth-century pioneer photographer and inventor. He made with John Johnson the world's first commercial photography portrait studio and patented the first US camera that made photographs.
Charles Cros
In 1860 Cros began studies in medicine, but he soon abandoned them for a life of literary and scientific pursuits. In 1869 he published a theory of color photography in which he proposed that a single scene could be photographed through glass filters colored green, violet, and orange. The three negatives obtained through those filters could be developed to produce positive impressions that contained varying amounts of red, yellow, and blue (the "antichromatic" or complementary colors of the filters). The three positive impressions, when superimposed on one another (for instance, by making three carbon prints using sufficiently transparent pigments, then transferring the pigmented gelatin onto a single support sheet) would recompose the original colors of the photographed scene. Cros's proposals, which anticipated the subtractive method of modern photography, were similar to more influential ideas advanced about the same time by Louis Ducos du Hauron. The same day, May 7, 1869, Charles Cros and Louis Ducos du Hauron presented their method of creating color photographs to the French Society of Photography. They had not been in communication beforehand and each knew nothing about the other's research. Cros ended up conceding the invention to Ducos Du Hauron, despite having deposited a sealed paper at the French Academy of Sciences on December 2, 1867. Ducos du Hauron had patented his ideas on November 28, 1868, almost a full year later, but claimed to have written an unpublished paper on the subject in 1862.
Julius Neubronner
From adolescence, Julius Neubronner was a passionate amateur photographer. In 1865 he found a camera for the Talbot system which his father had built on his own shortly after the invention of photography. All experiments with the obsolete camera failed, and together with a friend the boy secretly bought another camera on credit.
History of photography
After reading early reports of Daguerre's invention, Henry Fox Talbot, who had succeeded in creating stabilized photographic negatives on paper in 1835, worked on perfecting his own process. 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 a more efficient alternative to his original hot salt water method.
Talbot's early silver chloride "sensitive paper" experiments required camera exposures of an hour or more. In 1841, Talbot invented the calotype process, which, like Daguerre's process, used the principle of chemical development of a faint or invisible "latent" image to reduce the exposure time to a few minutes. 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 rephotographing it with a camera, a calotype negative could be used to make 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 a very broad interpretation of his patent, earning himself the ill will of photographers who were using the related glass-based processes later introduced by other inventors, but he was eventually defeated. 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 was not recognized as its inventor.
Optical communication
The photophone (originally given an alternate name, radiophone) is a communication device which allowed for the transmission of speech on a beam of light. It was invented jointly by Alexander Graham Bell and his assistant Charles Sumner Tainter on February 19, 1880, at Bell's 1325 'L' Street laboratory in Washington, D.C. Both were later to become full associates in the Volta Laboratory Association, created and financed by Bell.
René Dagron
René Prudent Patrice Dagron (17 March 1817 – 13 June 1900) was a French photographer and inventor. He was born in Aillières-Beauvoir, Sarthe, France.
On 21 June 1859, Dagron was granted the first microfilm patent in history. Dagron is also considered the inventor of the miniature photographic jewels () known as Stanhopes because a modified Stanhope lens is used to view the microscopic picture attached to the lens.
Scrapbooking
The advent of modern photography began with the first permanent photograph created by Joseph Nicéphore Niépce in 1826. This allowed the average person to begin to incorporate photographs into their scrapbooks. However, books or albums made specifically for showcasing photographs alone were not popularized in the United States until closer to 1860. Before that point, photographs were not thought of as items to be reproduced and shared. Demand for photo albums was spurred on in large part by the growing popularity of the carte de visite, a small photograph distributed in the same manner one might a visiting card. 
Old scrapbooks tended to have photos mounted with photomounting corners and perhaps notations of who was in a photo or where and when it was taken. They often included bits of memorabilia like newspaper clippings, letters, etc. An early known American scrapbooker and inventor of scrapbooking supplies was Mark Twain. Twain carried scrapbooks on his travels as he collected souvenirs, clippings and pictures.
Anna Atkins
Anna Atkins (née Children; 16 March 1799 – 9 June 1871) was an English botanist and photographer. She is often considered the first person to publish a book illustrated with photographic images. Some sources claim that she was the first woman to create a photograph.
Pictorialism
For the first forty years after a practical process of capturing and reproducing images was invented, photography remained the domain of a highly dedicated group of individuals who had expert knowledge of and skills in science, mechanics and art. To make a photograph, a person had to learn a great deal about chemistry, optics, light, the mechanics of cameras and how these factors combine to properly render a scene. It was not something that one learned easily or engaged in lightly, and, as such, it was limited to a relatively small group of academics, scientists and professional photographers.
All of that changed in a few years' time span. In 1888 George Eastman introduced the first handheld amateur camera, the Kodak camera. It was marketed with the slogan "You press the button, we do the rest." The camera was pre-loaded with a roll of film that produced about 100 2.5" round pictures exposures, and it could easily be carried and handheld during its operation. After all of the shots on the film were exposed, the whole camera was returned to the Kodak company in Rochester, New York, where the film was developed, prints were made, and new photographic film was placed inside. Then the camera and prints were returned to the customer, who was ready to take more pictures.
Angelo Sala
It was not until Sala's discovery was combined with the optical works of many other chemists, however, that photography was finally invented in the 1830s. His work was a major step towards a better understanding of chemical reactions and the realization that some substances are composed of chemical combinations of other substances. In 1625, Sala pursued his research interests in conjunction with his service as the personal physician to Johann Albrecht, Duke of Mecklenburg-in Gustow, and then after 1636 as physician to Johann Albrecht's successor, Duke Gustav Adolph in Butzow.
Georges Maroniez
Maroniez also became interested in photography and invented one of the first hand-held cameras, a device which he soon simplified, named the "Sphynx" and patented in 1891. The camera used a type of film invented by industrialist Victor Planchon (1863-1935), a relative of his. He travelled widely throughout the Mediterranean, North Africa and the Middle East, using his device to take over 1,600 images that are in the collection of the museum in Cambrai. Later he devised and patented a method of suppressing the vibrations and jerky movements produced by the cinematographs of the Lumière Brothers, which had its unveiling in 1899 at the Société Photographique in Cambrai.
Photography
The word "photography" was created from the Greek roots φωτός ("phōtos"), genitive of φῶς ("phōs"), "light" and γραφή ("graphé") "representation by means of lines" or "drawing", together meaning "drawing with light".
Robert Jefferson Bingham
Robert Jefferson Bingham (bapt. 7 March 1824 – 21 February 1870) was an English pioneer photographer, mainly active in France, making portraits and reproductions of paintings. He is one of the first photographers to use and write about the collodion process, which he claimed to have invented.
Photographophone
A photographophone is a device that was first developed by Ernst Ruhmer of Berlin, Germany in 1900. The Photographophone could record and reproduce speech and music through a celluloid film. The process started by speaking into a microphone. The electrical signal from the microphone through a transformer supplied electric current from a battery pack that caused a corresponding variation in the light of an arc (later used an incandescent lamp). The light from the arc lamp passes through the cylindrical lens slot which created sharp white lines on the moving sensitive film. This film, after being taken out of the box and developed, shows a series of perpendicular striations parallel to one another, which are really a photographic record of the sound waves originally entering the telephone transmitter. 
To reproduce the sound an projector directs light through the film traveling with the velocity equal to that with which the record is made. Behind the film a sensitive selenium cell is mounted receiving the variations in light producing a variation in its resistance and a corresponding effect in the telephone receivers connected.
William Nicholson Jennings
William Nicholson Jennings (1860–1946) was a photographer active in Philadelphia from the 1890s. Jennings was the first photographer to photograph lightning. He also conducted experiments with color photography and artificial lightning, helping in the development of photographic flash.
John Benjamin Dancer
John Benjamin Dancer (8 October 1812 – 24 November 1887) was a British scientific instrument maker and inventor of microphotography. He also pioneered stereography. By 1835, he controlled his father's instrument making business in Liverpool. He was responsible for various inventions, but did not patent many of his ideas. In 1856, he invented the stereoscopic camera (GB patent 2064/1856). He died at the age of 75 and was buried at Brooklands Cemetery, Sale, Greater Manchester.
Constance Fox Talbot
Constance Talbot (née Mundy, 30 January 1811 – 9 September 1880) was from 1832 the wife of William Henry Fox Talbot, one of the key players in the development of photography in the 1830s and 1840s. She herself briefly experimented with the process as early as 1839 and has been credited as the first woman ever to take a photograph – a hazy image of a short verse by the Irish poet Thomas Moore.
Pyréolophore
The Pyréolophore (, pea-ray-oh-loh-for) was one of the world's first internal combustion engines. It was invented in the early 19th century in Chalon-sur-Saône, France, by the Niépce brothers: Nicéphore (who went on to invent photography) and Claude. In 1807 the brothers ran a prototype internal combustion engine, and on 20 July 1807 a patent was granted by Napoleon Bonaparte after it had successfully powered a boat upstream on the river Saône.
History of photography
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 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 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 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 present the invention to the world (with the exception of Great Britain, where an agent for Daguerre patented it) as 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. It was superseded by the collodion process.
Robert Cornelius
Robert Cornelius (; March 1, 1809 – August 10, 1893) was an American pioneer of photography and a lamp manufacturer.
Photography
The German newspaper "Vossische Zeitung" of 25 February 1839 contained an article entitled "Photographie", discussing several priority claims – especially Henry Fox Talbot's – regarding Daguerre's claim of invention. The article is the earliest known occurrence of the word in public print. It was signed "J.M.", believed to have been Berlin astronomer Johann von Maedler.
Joseph Petzval
Petzval's greatest achievements lie in his work with geometric optics. In 1839, Louis Daguerre presented the Daguerreotype, the first commercially successful photographic process. Fox Talbot's calotype was discovered earlier but did not enjoy commercial success. Petzval learned of the invention from his friend, Viennese professor Andreas von Ettingshausen. The daguerreotype was problematic in that it required exposure times as long as 30 minutes to create a portrait. With Ettingshausen's urging, Petzval set up a workshop and laboratory at Kahlenberg in Vienna and, after six months of complex computations, produced designs for improved objective lenses for both portraiture and landscape photography. Because the artillery was one of the few occupations that used advanced mathematical computations at the time, Archduke Ludwig lent eight artillery cannoners and three corporals to the computational efforts. The calculations these men carried out in tandem with each other have been regarded as an early (albeit human) example of a parallel computer.
Richard Buckley Litchfield
Litchfield was a fellow Working Men's College colleague of John Ruskin. He married a daughter of Charles Darwin, Henrietta Emma ('Etty') Darwin, in 1871, but there were no children from the marriage. He wrote a substantial biography of the inventor of photography, Thomas Wedgwood, which was published in the year of his death.
Dean M. Peterson
Dean McCormack Peterson (1931–2004) was an American inventor, responsible for two of consumer photography's largest revolutions: the Kodak Instamatic camera, introduced in 1963, and the panoply of "point-and-shoot" cameras introduced in the late 1970s. Both of these inventions had a huge impact on consumer photography, and nearly every snapshot taken since the mid-1960s, and virtually every photo of any kind since the 1980s, have benefited from Peterson's pioneering work.
Photography
Niépce died in 1833 and Daguerre then redirected the experiments toward the light-sensitive silver halides, which Niépce had abandoned many years earlier because of his inability to make the images he captured with them light-fast and permanent. Daguerre's efforts culminated in what would later be named the daguerreotype process. The essential elements—a silver-plated surface sensitized by iodine vapor, developed by mercury vapor, and "fixed" with hot saturated salt water—were in place in 1837. The required exposure time was measured in minutes instead of hours. Daguerre took the earliest confirmed photograph of a person in 1838 while capturing a view of a Paris street: unlike the other pedestrian and horse-drawn traffic on the busy boulevard, which appears deserted, one man having his boots polished stood sufficiently still throughout the several-minutes-long exposure to be visible. The existence of Daguerre's process was publicly announced, without details, on 7 January 1839. The news created an international sensation. France soon agreed to pay Daguerre a pension in exchange for the right to present his invention to the world as the gift of France, which occurred when complete working instructions were unveiled on 19 August 1839. In that same year, American photographer Robert Cornelius is credited with taking the earliest surviving photographic self-portrait.
History of photography
Georg Fabricius (1516–71) discovered silver chloride, later used to make photographic paper.
Louis Dodero
Louis Dodero was a French photographer from Marseilles. He is credited with inventing the Carte de visite in 1851. However, another photographer, André-Adolphe-Eugène Disdéri patented this type of photograph on November 27, 1854.
Johann Pucher
As a schoolchild, Pucher was interested in art, languages, and the natural sciences, especially chemistry and physics. He wanted to study art, but obeyed his mother's wish and became a Catholic priest. However, he continued to experiment in photography, art, and music. When the French Academy of Sciences announced the invention of the daguerreotype on 19 August 1839, Pucher quickly mastered the process, but it was too expensive, so he developed his own way of making photographs. On 19 April 1842, he invented a photographic process on glass that he called the hyalotype, or "svetlopis" in Slovene. His photos are also called puharotypes, in his honor. The first report about his invention was published in the newspaper "Carniolia" in 1841.
Anatol Josepho
Anatol Marco Josepho (March 31, 1894 – December 16, 1980), born Anatol Josephewitz, was a Jewish Siberian immigrant to the United States from Omsk, Russia, who invented and patented the first automated photo booth in 1925, which was named the "Photomaton". In 1927, he was paid one million dollars for the invention.
Louis Daguerre
In 1829, Daguerre partnered with Nicéphore Niépce, an inventor who had produced the world's first heliograph in 1822 and the oldest surviving camera photograph in 1826 or 1827. Niépce died suddenly in 1833, but Daguerre continued experimenting, and evolved the process which would subsequently be known as the daguerreotype. After efforts to interest private investors proved fruitless, Daguerre went public with his invention in 1839. At a joint meeting of the French Academy of Sciences and the Académie des Beaux Arts on 7 January of that year, the invention was announced and described in general terms, but all specific details were withheld. Under assurances of strict confidentiality, Daguerre explained and demonstrated the process only to the Academy's perpetual secretary François Arago, who proved to be an invaluable advocate. Members of the Academy and other select individuals were allowed to examine specimens at Daguerre's studio. The images were enthusiastically praised as nearly miraculous, and news of the daguerreotype quickly spread. Arrangements were made for Daguerre's rights to be acquired by the French Government in exchange for lifetime pensions for himself and Niépce's son Isidore; then, on 19 August 1839, the French Government presented the invention as a gift from France "free to the world", and complete working instructions were published. In 1839, he was elected to the National Academy of Design as an Honorary Academician.
