History of Photography

The history of photography has roots in remote antiquity with the discovery of two critical principles, that of the camera obscura image projection and the fact that some substances are visibly altered by exposure to light, as discovered by observation. Apart from a very uncertain process used on the Turin Shroud there are no artifacts or descriptions that indicate that anyone even imagined capturing images with light sensitive materials before the 18th century. Around 1717 Johann Heinrich Schulze captured cut-out letters on a bottle of a light-sensitive slurry, but he apparently never thought of making the results durable. Around 1800 Thomas Wedgwood made the first reliably documented, although unsuccessful attempt at capturing camera images in permanent form. His experiments did produce detailed photograms, but Wedgwood and his associate Humphry Davy found no way to fix these images.

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.[1][2] 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.

The commercial introduction of computer-based electronic digital cameras in the 1990s soon revolutionized photography. During the first decade of the 21st century, traditional film-based photochemical methods were increasingly marginalized as the practical advantages of the new technology became widely appreciated and the image quality of moderately priced digital cameras was continually improved. Especially since cameras became a standard feature on smartphones, taking pictures (and instantly publishing them online) has become an ubiquitous everyday practice around the world.

Etymology

The coining of the word "photography" is usually attributed to Sir John Herschel in 1839. It is based on the Greek (ph?s), (genitive: ph?tós) meaning "light", and (graphê), meaning "drawing, writing", together meaning "drawing with light".[3]

Early history of the camera

Principle of a box camera obscura with mirror

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.

Before 1700: Turin Shroud + light sensitive materials

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.[4] 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.[5]

The Shroud of Turin: modern photo of the face, positive left, digitally processed negative image right

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.[6] No other examples of detailed negative images from before the 19th century are known.[]

Albertus Magnus (1193/1206-80) discovered silver nitrate and noted that it could blacken skin.[7] Silver nitrate would later be used as a light sensitive material in the photographic emulsion on photographic glass plates and film.

Georg Fabricius (1516-71) discovered silver chloride, later used to make photographic paper.[8]

In 1614 Angelo Sala wrote in his paper Septem Planetarum terrestrium Spagirica recensio[9]: "When you expose powdered silver nitrate to sunlight, it turns black as ink". He also noted that paper wrapped around silver nitrate for a year had turned black.[10]

Wilhelm Homberg described how light darkened some chemicals (photochemical effect) in 1694.[8]

1700 to 1802: Earliest concepts and fleeting photogram results

Schulze's Scotophorus: earliest fleeting letter photograms (circa 1717)

Around 1717[11] German polymath Johann Heinrich Schulze accidentally discovered that a slurry of chalk and nitric acid into which some silver particles had been dissolved was darkened by sunlight. After experiments with threads that had created lines on the bottled substance after he placed it in direct sunlight for a while, he applied stencils of words to the bottle. The stencils produced copies of the text in dark red, almost violet characters on the surface of the otherwise whitish contents. The impressions persisted until they were erased by shaking the bottle or until overall exposure to light obliterated them. Schulze named the substance "Scotophorus", when he published his findings in 1719. He thought the discovery could be applied to detect whether metals or minerals contained any silver and hoped that further experimentation by others would lead to some other useful results.[12][13] Schulze's process resembled later photogram techniques and is sometimes regarded as the very first form of photography.[14]

De la Roche's imagined image capturing process (1760)

The early science fiction novel Giphantie[15] (1760) by the French Tiphaigne de la Roche described something quite similar to (colour) photography, a process that fixes fleeting images formed by rays of light:"They coat a piece of canvas with this material, and place it in front of the object to capture. The first effect of this cloth is similar to that of a mirror, but by means of its viscous nature the prepared canvas, as is not the case with the mirror, retains a facsimile of the image. The mirror represents images faithfully, but retains none; our canvas reflects them no less faithfully, but retains them all. This impression of the image is instantaneous. The canvas is then removed and deposited in a dark place. An hour later the impression is dry, and you have a picture the more precious in that no art can imitate its truthfulness."[16] De la Roche thus imagined a process that made use of a special substance in combination with the qualities of a mirror, rather than the camera obscura. The hour of drying in a dark place suggests he possibly thought about the light sensitivity of the material, but he attributes the effect to its viscous nature.

Scheele's forgotten chemical fixer (1777)

In 1777, the chemist Carl Wilhelm Scheele was studying the more intrinsically light-sensitive silver chloride and determined that light darkened it by disintegrating it into microscopic dark particles of metallic silver. Of greater potential usefulness, Scheele found that ammonia dissolved the silver chloride but not the dark particles. This discovery could have been used to stabilize or "fix" a camera image captured with silver chloride, but was not picked up by the earliest photography experimenters.[]

Scheele also noted that red light did not have much effect on silver chloride (a feature that would later be applied to be able to see while printing black and white photographs in darkrooms).[17]

Although Thomas Wedgwood felt inspired by Scheele's writings in general, he must have missed or forgotten these experiments: he found no method to fix the photogram and shadow images he managed to capture around 1800 (see below).[17]

Thomas Wedgwood & Humphry Davy: Fleeting detailed photograms (1790?-1802)

Thomas Wedgwood (1771-1805) is believed to have been the first person to have thought of creating permanent pictures by capturing camera images on material coated with a light-sensitive chemical. He originally wanted to capture the images of a camera obscura, but found they were too faint to have an effect upon the silver nitrate solution that was advised to him as a light-sensitive substance. Wedgwood did manage to copy painted glass plates and captured shadows on white leather as well as on paper moistened with a silver nitrate solution. Attempts to preserve the results with their "distinct tints of brown or black, sensibly differing in intensity" failed. It is unclear when Wedgwood's experiments took place. He may have started before 1790; James Watt wrote a letter to Thomas Wedgwood's father Josiah Wedgwood to thank him "for your instructions as to the Silver Pictures, about which, when at home, I will make some experiments". This letter (now lost) is believed to have been written in 1790, 1791 or 1799. In 1802 an account by Humphry Davy detailing Wedgwood's experiments was published in an early journal of the Royal Institution with the title An Account of a Method of Copying Paintings upon Glass, and of Making Profiles, by the Agency of Light upon Nitrate of Silver. Davy added that the method could be used for objects that are partly opaque and partly transparent to create accurate representations of for instance "the woody fibres of leaves and the wings of insects". He also found that solar microscope images of small objects were easily captured on prepared paper. Davy, apparently unaware or forgetful about Scheele's discovery, concluded that substances should be found to get rid of (or deactivate) the unexposed particles in silver nitrate or silver chloride "to render the process as useful as it is elegant".[17] Wedgwood may have prematurely abandoned his experiments due to his frail and failing health. He died aged 34 in 1805.

Davy seems not to have continued the experiments. Although the journal of the small, infant Royal Institution probably reached its very small group of members, the article eventually must have been read by much more people. It was reviewed by David Brewster in the Edinburgh Magazine in December 1802, appeared in chemistry textbooks as early as 1803, was translated into French, and published in German in 1811. Readers of the article may have been discouraged to find a fixer, because the highly acclaimed scientist Davy had already tried and failed. Apparently the article wasn't noted by Niépce nor Daguerre, and by Talbot only after he had developed his own processes.[17][18]

Jacques Charles: Fleeting silhouette photograms (circa 1801?)

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 Westwood. 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 Daguerreotupe 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.[19] 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.

1816 to 1833: Niépce's earliest fixed images

The earliest known surviving heliographic engraving, made in 1825. It was printed from a metal plate made by Joseph Nicéphore Niépce with his "heliographic process".[20] The plate was exposed under an ordinary engraving and copied it by photographic means. This was a step towards the first permanent photograph from nature taken with a camera obscura.
"Boulevard du Temple", a daguerreotype made by Louis Daguerre in 1838, is generally accepted as the earliest photograph to include people. It is a view of a busy street, but because the exposure lasted for several minutes the moving traffic left no trace. Only the two men near the bottom left corner, one of them apparently having his boots polished by the other, remained in one place long enough to be visible.

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.[21]

Not all early portraits are stiff and grim-faced records of a posing ordeal. This pleasant expression was captured by Mary Dillwyn in Wales in 1853.

The oldest surviving photograph of the image formed in a camera was created by Niépce in 1826 or 1827.[1] It was made on a polished sheet of pewter and the light-sensitive substance was a thin coating of bitumen, a naturally occurring petroleum tar, which was dissolved in lavender oil, applied to the surface of the pewter and allowed to dry before use.[23] After a very long exposure in the camera (traditionally said to be eight hours, but now believed to be several days),[24] the bitumen was sufficiently hardened in proportion to its exposure to light that the unhardened part could be removed with a solvent, leaving a positive image with the light areas represented by hardened bitumen and the dark areas by bare pewter.[23] To see the image plainly, the plate had to be lit and viewed in such a way that the bare metal appeared dark and the bitumen relatively light.[21]

In partnership, Niépce in Chalon-sur-Saône and Louis Daguerre in Paris refined the bitumen process,[25] substituting a more sensitive resin and a very different post-exposure treatment that yielded higher-quality and more easily viewed images. Exposure times in the camera, although substantially reduced, were still measured in hours.[21]

1830 to 1840: early monochrome processes

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,[26] and the news quickly spread.[27] 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.[28] 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.[29] Complete instructions were made public on 19 August 1839.[30] Known as the Daguerreotype process, it was the most common commercial process until the late 1850s. It was superseded by the collodion process.

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.[31] News of this solvent also benefited Daguerre, who soon adopted it as a more efficient alternative to his original hot salt water method.[32]

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,[33] 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.

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.[34] 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.[35]

1850 to 1900

In 1851 Frederick Scott Archer invented the collodion process.[36] Photographer and children's author Lewis Carroll used this process. (Carroll refers to the process as "Tablotype" [sic] in the story "A Photographer's Day Out")[37]

Herbert Bowyer Berkeley experimented with his own version of collodion emulsions after Samman introduced the idea of adding dithionite to the pyrogallol developer.[] Berkeley discovered that with his own addition of sulfite, to absorb the sulfur dioxide given off by the chemical dithionite in the developer, that dithionite was not required in the developing process. In 1881 he published his discovery. Berkeley's formula contained pyrogallol, sulfite and citric acid. Ammonia was added just before use to make the formula alkaline. The new formula was sold by the Platinotype Company in London as Sulpho-Pyrogallol Developer.[38]

Nineteenth-century experimentation with photographic processes frequently became proprietary.The German-born, New Orleans photographer Theodore Lilienthal successfully sought legal redress in an 1881 infringement case involving his "Lambert Process" in the Eastern District of Louisiana.

Popularization

The daguerreotype proved popular in response to the demand for portraiture that emerged from the middle classes during the Industrial Revolution.[] This demand, which could not be met in volume and in cost by oil painting, added to the push for the development of photography.

Roger Fenton and Philip Henry Delamotte helped popularize the new way of recording events, the first by his Crimean war pictures, the second by his record of the disassembly and reconstruction of The Crystal Palace in London. Other mid-nineteenth-century photographers established the medium as a more precise means than engraving or lithography of making a record of landscapes and architecture: for example, Robert Macpherson's broad range of photographs of Rome, the interior of the Vatican, and the surrounding countryside became a sophisticated tourist's visual record of his own travels.

In America, by 1851 a broadside by daguerreotypist Augustus Washington was advertising prices ranging from 50 cents to $10.[39] However, daguerreotypes were fragile and difficult to copy. Photographers encouraged chemists to refine the process of making many copies cheaply, which eventually led them back to Talbot's process.

Ultimately, the photographic process came about from a series of refinements and improvements in the first 20 years. In 1884 George Eastman, of Rochester, New York, developed dry gel on paper, or film, to replace the photographic plate so that a photographer no longer needed to carry boxes of plates and toxic chemicals around. In July 1888 Eastman's Kodak camera went on the market with the slogan "You press the button, we do the rest". Now anyone could take a photograph and leave the complex parts of the process to others, and photography became available for the mass-market in 1901 with the introduction of the Kodak Brownie.

Early Photography in India

Daguerreotype cameras were advertised in Calcutta a year after their invention in France -- but photographic societies in Bombay, Calcutta and Madras were beginning to pop up from the 1850s onward. [40] As the practice of photography evolved, a contrasting style developed alongside the predominantly European influence on the art form. This turn is most notable in the work of Raja Deen Dayal, India's most celebrated 19th-century photographer, whose appointment as court photographer to the sixth Nizam of Hyderabad allowed him unique access to the inner circles of aristocratic life. [41]

Perhaps Mrs. E. Mayer holds the distinction of being the first professional woman photographer in India. She opened a studio in 7 Old Court House Street Corner to provide a rare treat to Indian women: to be photographed without fear or concern. [42]

Color process

The first durable color photograph, taken by Thomas Sutton in 1861

A practical means of color photography was sought from the very beginning. Results were demonstrated by Edmond Becquerel as early as 1848, but exposures lasting for hours or days were required and the captured colors were so light-sensitive they would only bear very brief inspection in dim light.

The first durable color photograph was a set of three black-and-white photographs taken through red, green, and blue color filters and shown superimposed by using three projectors with similar filters. It was taken by Thomas Sutton in 1861 for use in a lecture by the Scottish physicist James Clerk Maxwell, who had proposed the method in 1855.[43] The photographic emulsions then in use were insensitive to most of the spectrum, so the result was very imperfect and the demonstration was soon forgotten. Maxwell's method is now most widely known through the early 20th century work of Sergei Prokudin-Gorskii. It was made practical by Hermann Wilhelm Vogel's 1873 discovery of a way to make emulsions sensitive to the rest of the spectrum, gradually introduced into commercial use beginning in the mid-1880s.

Two French inventors, Louis Ducos du Hauron and Charles Cros, working unknown to each other during the 1860s, famously unveiled their nearly identical ideas on the same day in 1869. Included were methods for viewing a set of three color-filtered black-and-white photographs in color without having to project them, and for using them to make full-color prints on paper.[44]

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.[45] 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.

A color portrait of Mark Twain by Alvin Langdon Coburn, 1908, made by the recently introduced Autochrome process

Autochrome plates had an integral mosaic filter layer with roughly five million previously dyed potato grains per square inch added to the surface. Then through the use of a rolling press, five tons of pressure were used to flatten the grains, enabling every one of them to capture and absorb color and their microscopic size allowing the illusion that the colors are merged together. The final step was adding a coat of the light capturing substance silver bromide after which a color image could be imprinted and developed. In order to see it, reversal processing was used to develop each plate into a transparent positive that could be viewed directly or projected with an ordinary projector. One of the drawbacks of the technology is an exposure time of at least a second was required during the day in bright light and the worse the light is, the time required quickly goes up. An indoor portrait required a few minutes with the subject not being able to move or else the picture would come out blurry. This was because the grains absorbed the color fairly slowly and that a filter of a yellowish-orange color was added to the plate to keep the photograph from coming out excessively blue. Although necessary, the filter had the effect of reducing the amount of light that was absorbed. Another drawback was that the film could only be enlarged so much until the many dots that make up the image become apparent.[45][46]

Competing screen plate products soon appeared and film-based versions were eventually made. All were expensive and until the 1930s none was "fast" enough for hand-held snapshot-taking, so they mostly served a niche market of affluent advanced amateurs.

A new era in color photography began with the introduction of Kodachrome film, available for 16 mm home movies in 1935 and 35 mm slides in 1936. It captured the red, green, and blue color components in three layers of emulsion. A complex processing operation produced complementary cyan, magenta, and yellow dye images in those layers, resulting in a subtractive color image. Maxwell's method of taking three separate filtered black-and-white photographs continued to serve special purposes into the 1950s and beyond, and Polachrome, an "instant" slide film that used the Autochrome's additive principle, was available until 2003, but the few color print and slide films still being made in 2015 all use the multilayer emulsion approach pioneered by Kodachrome.

Development of digital photography

Walden Kirsch as scanned into the SEAC computer in 1957

In 1957, a team led by Russell A. Kirsch at the National Institute of Standards and Technology developed a binary digital version of an existing technology, the wirephoto drum scanner, so that alphanumeric characters, diagrams, photographs and other graphics could be transferred into digital computer memory. One of the first photographs scanned was a picture of Kirsch's infant son Walden. The resolution was 176x176 pixels with only one bit per pixel, i.e., stark black and white with no intermediate gray tones, but by combining multiple scans of the photograph done with different black-white threshold settings, grayscale information could also be acquired.[47]

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). Today sites and apps such as Flickr, Picasa, Instagram, Imgur and PhotoBucket are used by many millions of people to share their pictures.

The traditional estimate of eight or nine hours originated in the 1950s and is based mainly on the fact that sunlight strikes the buildings as if from an arc across the sky, an effect which several days of continuous exposure would also produce.

(This overabundance contributes towards giving red tones, even while completely removing the iodine by means of a rinse in sodium hyposulfite or in sea salt.)
