Louis-Jacques-Mandé Daguerre ( // ; French: [dagɛʁ] ; 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.
Louis Daguerre was born in Cormeilles-en-Parisis, Val-d'Oise, France. He was apprenticed in architecture, theatre design, and panoramic painting to Pierre Prévost, the first French panorama painter. Exceedingly adept at his skill of theatrical illusion, he became a celebrated designer for the theatre, and later came to invent the diorama, which opened in Paris in July 1822.
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.
Daguerre died, from a heart attack, 12 km (7 mi) from Paris. A monument marks his grave there.on 10 July 1851 in Bry-sur-Marne,
Daguerre's name is one of the 72 names inscribed on the Eiffel tower.
In the mid-1820s, prior to his association with Daguerre, Niépce used a coating of bitumen of Judea to make the first permanent camera photographs. The bitumen was hardened where it was exposed to light and the unhardened portion was then removed with a solvent. A camera exposure lasting for hours or days was required. Niépce and Daguerre later refined this process, but unacceptably long exposures were still needed.
After the death of Niépce in 1833, Daguerre concentrated his attention on the light-sensitive properties of silver salts, which had previously been demonstrated by Johann Heinrich Schultz and others. For the process which was eventually named the daguerreotype, he exposed a thin silver-plated copper sheet to the vapour given off by iodine crystals, producing a coating of light-sensitive silver iodide on the surface. The plate was then exposed in the camera. Initially, this process, too, required a very long exposure to produce a distinct image, but Daguerre made the crucial discovery that an invisibly faint "latent" image created by a much shorter exposure could be chemically "developed" into a visible image. Upon seeing the image, the contents of which are unknown, Daguerre said, "I have seized the light – I have arrested its flight!"
The latent image on a daguerreotype plate was developed by subjecting it to the vapour given off by mercury heated to 75 °C. The resulting visible image was then "fixed" (made insensitive to further exposure to light) by removing the unaffected silver iodide with concentrated and heated salt water. Later, a solution of the more effective "hypo" (hyposulphite of soda, now known as sodium thiosulfate) was used instead.
The resultant plate produced an exact reproduction of the scene. The image was laterally reversed—as images in mirrors are—unless a mirror or inverting prism was used during exposure to flip the image. To be seen optimally, the image had to be lit at a certain angle and viewed so that the smooth parts of its mirror-like surface, which represented the darkest parts of the image, reflected something dark or dimly lit. The surface was subject to tarnishing by prolonged exposure to the air and was so soft that it could be marred by the slightest friction, so a daguerreotype was almost always sealed under glass before being framed (as was commonly done in France) or mounted in a small folding case (as was normal in the UK and US).
Daguerreotypes were usually portraits; the rarer landscape views and other unusual subjects are now much sought-after by collectors and sell for much higher prices than ordinary portraits. At the time of its introduction, the process required exposures lasting ten minutes or more for brightly sunlit subjects, so portraiture was an impractical ordeal. Samuel Morse was astonished to learn that daguerreotypes of the streets of Paris did not show any people, horses or vehicles, until he realized that due to the long exposure times all moving objects became invisible. Within a few years, exposures had been reduced to as little as a few seconds by the use of additional sensitizing chemicals and "faster" lenses such as Petzval's portrait lens, the first mathematically calculated lens.
The daguerreotype was the Polaroid film of its day: it produced a unique image which could only be duplicated by using a camera to photograph the original. Despite this drawback, millions of daguerreotypes were produced. The paper-based calotype process, introduced by Henry Fox Talbot in 1841, allowed the production of an unlimited number of copies by simple contact printing, but it had its own shortcomings—the grain of the paper was obtrusively visible in the image, and the extremely fine detail of which the daguerreotype was capable was not possible. The introduction of the wet collodion process in the early 1850s provided the basis for a negative-positive print-making process not subject to these limitations, although it, like the daguerreotype, was initially used to produce one-of-a-kind images—ambrotypes on glass and tintypes on black-lacquered iron sheets—rather than prints on paper. These new types of images were much less expensive than daguerreotypes, and they were easier to view. By 1860 few photographers were still using Daguerre's process.
The same small ornate cases commonly used to house daguerreotypes were also used for images produced by the later and very different ambrotype and tintype processes, and the images originally in them were sometimes later discarded so that they could be used to display photographic paper prints. It is now a very common error for any image in such a case to be described as "a daguerreotype". A true daguerreotype is always an image on a highly polished silver surface, usually under protective glass. If it is viewed while a brightly lit sheet of white paper is held so as to be seen reflected in its mirror-like metal surface, the daguerreotype image will appear as a relatively faint negative—its dark and light areas reversed—instead of a normal positive. Other types of photographic images are almost never on polished metal and do not exhibit this peculiar characteristic of appearing positive or negative depending on the lighting and reflections.
Unbeknownst to either inventor, Daguerre's developmental work in the mid-1830s coincided with photographic experiments being conducted by William Henry Fox Talbot in England. Talbot had succeeded in producing a "sensitive paper" impregnated with silver chloride and capturing small camera images on it in the summer of 1835, though he did not publicly reveal this until January 1839. Talbot was unaware that Daguerre's late partner Niépce had obtained similar small camera images on silver-chloride-coated paper nearly twenty years earlier. Niépce could find no way to keep them from darkening all over when exposed to light for viewing and had therefore turned away from silver salts to experiment with other substances such as bitumen. Talbot chemically stabilized his images to withstand subsequent inspection in daylight by treating them with a strong solution of common salt.
When the first reports of the French Academy of Sciences announcement of Daguerre's invention reached Talbot, with no details about the exact nature of the images or the process itself, he assumed that methods similar to his own must have been used, and promptly wrote an open letter to the Academy claiming priority of invention. Although it soon became apparent that Daguerre's process was very unlike his own, Talbot had been stimulated to resume his long-discontinued photographic experiments. The developed out daguerreotype process only required an exposure sufficient to create a very faint or completely invisible latent image which was then chemically developed to full visibility. Talbot's earlier "sensitive paper" (now known as "salted paper") process was a printed out process that required prolonged exposure in the camera until the image was fully formed, but his later calotype (also known as talbotype) paper negative process, introduced in 1841, also used latent image development, greatly reducing the exposure needed, and making it competitive with the daguerreotype.
Daguerre's agent Miles Berry applied for a British patent under the instruction of Daguerre just days before France declared the invention "free to the world". The United Kingdom was thereby uniquely denied France's free gift, and became the only country where the payment of license fees was required. This had the effect of inhibiting the spread of the process there, to the eventual advantage of competing processes which were subsequently introduced into England. Antoine Claudet was one of the few people legally licensed to make daguerreotypes in Britain.
In the spring of 1821, Daguerre partnered with Charles Marie Bouton with the common goal of creating a diorama theatre. Daguerre had expertise in lighting and scenic effects, and Bouton was the more experienced painter. However, Bouton eventually withdrew, and Daguerre acquired sole responsibility of the diorama theatre.
The first diorama theatre was built in Paris, adjacent to Daguerre's studio. The first exhibit opened 11 July 1822 showing two tableaux, one by Daguerre and one by Bouton. This would become a pattern. Each exhibition would typically have two tableaux, one each by Daguerre and Bouton. Also, one would be an interior depiction, and the other would be a landscape. Daguerre hoped to create a realistic illusion for an audience, and wanted audiences to be not only entertained, but awe-stricken. The diorama theatres were magnificent in size. A large translucent canvas, measuring around 70 ft wide and 45 ft tall, was painted on both sides. These paintings were vivid and detailed pictures, and were lit from different angles. As the lights changed, the scene would transform. The audience would begin to see the painting on the other side of the screen. The effect was awe-inspiring. "Transforming impressions, mood changes, and movements were produced by a system of shutters and screens that allowed light to be projected- from behind- on alternately separate sections of an image painted on a semi-transparent backdrop" (Szalczer).
Because of their size, the screens had to remain stationary. Since the tableaux were stationary, the auditorium revolved from one scene to another. The auditorium was a cylindrical room and had a single opening in the wall, similar to a proscenium arch, through which the audience could watch a "scene". Audiences would average around 350, and most would stand, though limited seating was provided. Twenty-one diorama paintings were exhibited in the first eight years. These included ‘Trinity Chapel in Canterbury Cathedral’, ‘Chartres Cathedral’, ‘City of Rouen’, and ‘Environs of Paris’ by Bouton; ‘Valley of Sarnen’, ‘Harbour of Brest’, ‘Holyroodhouse Chapel’, and ‘Roslin Chapel’ by Daguerre.
The Roslin Chapel was known for a few legends involving an unconsuming fire. The legend goes that the Chapel has appeared to be in flames just before a high-status death, but has later shown no damage from any such fire. This chapel was also known for being unique in its architectural beauty. Daguerre was aware of both of these aspects of Roslin Chapel, and this made it a perfect subject for his diorama painting. The legends connected with the chapel would be sure to attract a large audience. Interior of Roslin Chapel in Paris opened 24 September 1824 and closed February 1825. The scene depicted light coming in through a door and a window. Foliage shadows could be seen at the window, and the way the light's rays shone through the leaves was breathtaking and seemed to "go beyond the power of painting" (Maggi). Then the light faded on the scene as if a cloud was passing over the sun. The Times dedicated an article to the exhibition, calling it "perfectly magical".
Diorama became a popular new medium, and imitators arose. It is estimated that profits reached as much as 200,000 francs. This would require 80,000 visitors at an entrance fee of 2.50 francs. Another diorama theatre opened in London, taking only four months to build. It opened in September 1823. The most prosperous years were the early to mid-1820s.
The dioramas prospered for a few years until going into the 1830s. Then, inevitably, the theatre burned down. The diorama had been Daguerre's only source of income. At first glance, the event was tragically fateful. But the enterprise was already close to its end, thus losing the diorama tableaux was not completely disastrous, considering the funds granted under the insurance.
Photography is the art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing, and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication.
A photograph is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating such images is called photography.
The following list comprises significant milestones in the development of photography technology.
Calotype or talbotype is an early photographic process introduced in 1841 by William Henry Fox Talbot, using paper coated with silver iodide. The term calotype comes from the Greek καλός (kalos), "beautiful", and τύπος (tupos), "impression".
William Henry Fox Talbot FRS FRSE FRAS was an English scientist, inventor and photography pioneer who invented the salted paper and calotype processes, precursors to photographic processes of the later 19th and 20th centuries. His work, in the 1840s on photomechanical reproduction, led to the creation of the photoglyphic engraving process, the precursor to photogravure. He was the holder of a controversial patent that affected the early development of commercial photography in Britain. He was also a noted photographer who contributed to the development of photography as an artistic medium. He published The Pencil of Nature (1844–46), which was illustrated with original salted paper prints from his calotype negatives, and made some important early photographs of Oxford, Paris, Reading, and York.
The daguerreotype process, or daguerreotypy, was the first publicly available photographic process, widely used during the 1840s and 1850s.
Joseph Nicéphore Niépce, commonly known or referred to simply as Nicéphore Niépce, 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 Niépce.
Johann Augustin Pucher was a Slovene priest, scientist, photographer, artist, and poet who invented an unusual process for making photographs on glass.
Hippolyte Bayard 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.
Photogravure is an intaglio printmaking or photo-mechanical process whereby a copper plate is grained and then coated with a light-sensitive gelatin tissue which had been exposed to a film positive, and then etched, resulting in a high quality intaglio plate that can reproduce detailed continuous tones of a photograph.
Photoengraving is a process that uses a light-sensitive photoresist applied to the surface to be engraved to create a mask that shields some areas during a subsequent operation which etches, dissolves, or otherwise removes some or all of the material from the unshielded areas. Normally applied to metal, it can also be used on glass, plastic and other materials.
Heliography from helios, meaning "sun", and graphein (γράφειν), "writing") is the photographic process invented by Joseph Nicéphore Niépce around 1822, which he used to make the earliest known surviving photograph from nature, View from the Window at Le Gras, and the first realisation of photoresist as means to reproduce artworks through inventions of photolithography and photogravure.
The history of photography began in remote antiquity with the discovery of two critical principles: camera obscura image projection and the observation that some substances are visibly altered by exposure to light. There are no artifacts or descriptions that indicate any attempt to capture images with light sensitive materials prior to the 18th century.
The history of the camera begins even before the introduction of photography. Cameras evolved from the camera obscura through many generations of photographic technology – daguerreotypes, calotypes, dry plates, film – to the modern day with digital cameras and camera phones.
The following outline is provided as an overview of and topical guide to photography:
Travel photography is a genre of photography that may involve the documentation of an area's landscape, people, cultures, customs and history. The Photographic Society of America defines a travel photo as an image that expresses the feeling of a time and place, portrays a land, its people, or a culture in its natural state, and has no geographical limitations.
The physautotype was a photographic process, invented by Joseph Nicéphore Niépce and Louis Jacques Mandé Daguerre in 1832, in which images were produced by the use of lavender oil residue dissolved in alcohol as the photographic agent. The solution was coated onto a silver or glass plate and allowed to dry, after which it had a powdery white appearance. The plate was then exposed in a camera obscura for about 8 hours and developed with petroleum-based spirit vapors, which caused the least strongly exposed areas to become proportionally more transparent, creating a photographic image that was positive when viewed against a darker background.
View from the Window at Le Gras is a heliographic image and the oldest surviving camera photograph. It was created by French inventor Nicéphore Niépce in 1827 in Saint-Loup-de-Varennes, France, and shows parts of the buildings and surrounding countryside of his estate, Le Gras, as seen from a high window.
The French firm Susse Frères manufactured a daguerreotype camera which was one of the first two photographic cameras ever sold to the public. The company was also engaged in the foundry business and owned a large foundry in Paris.
The Boulevard du Temple photograph of 1838 is one of the earliest daguerrotype plates produced by Louis Daguerre. Although the image seems to be of a deserted street, it is widely considered to be the first photograph to include an image of people.
from Helmut Gernsheim's article, "The 150th Anniversary of Photography," in History of Photography, Vol. I, No. 1, January 1977: ... In 1822, Niépce coated a glass plate ... The sunlight passing through ... This first permanent example ... was destroyed ... some years later.
A practical description of that process called the daguerreotype.
