General considerations

As a means of visual communication and expression, photography has distinct aesthetic capabilities. In order to understand them, one must first understand the characteristics of the process itself. One of the most important characteristics is immediacy. Usually, but not necessarily, the image that is recorded is formed by a lens in a camera. Upon exposure to the light forming the image, the sensitive material undergoes changes in its structure, a latent (but reversed) image usually called a negative is formed, and the image becomes visible by development and permanent by fixing with sodium thiosulfate, called “hypo.” With modern materials, the processing may take place immediately or may be delayed for weeks or months.

The essential elements of the image are usually established immediately at the time of exposure. This characteristic is unique to photography and sets it apart from other ways of picture making. The seemingly automatic recording of an image by photography has given the process a sense of authenticity shared by no other picture-making technique. The photograph possesses, in the popular mind, such apparent accuracy that the adage “the camera does not lie” has become an accepted, if erroneous, cliché.

This understanding of photography’s supposed objectivity has dominated evaluations of its role in the arts. In the early part of its history, photography was sometimes belittled as a mechanical art because of its dependence on technology. In truth, however, photography is not the automatic process that is implied by the use of a camera. Although the camera usually limits the photographer to depicting existing objects rather than imaginary or interpretive views, the skilled photographer can introduce creativity into the mechanical reproduction process. The image can be modified by different lenses and filters. The type of sensitive material used to record the image is a further control, and the contrast between highlight and shadow can be changed by variations in development. In printing the negative, the photographer has a wide choice in the physical surface of the paper, the tonal contrast, and the image colour. The photographer also may set up a completely artificial scene to photograph.

The most important control is, of course, the creative photographer’s vision. He or she chooses the vantage point and the exact moment of exposure. The photographer perceives the essential qualities of the subject and interprets it according to his or her judgment, taste, and involvement. An effective photograph can disseminate information about humanity and nature, record the visible world, and extend human knowledge and understanding. For all these reasons, photography has aptly been called the most important invention since the printing press.
Inventing the medium » Antecedents

The forerunner of the camera was the camera obscura, a dark chamber or room with a hole (later a lens) in one wall, through which images of objects outside the room were projected on the opposite wall. The principle was probably known to the Chinese and to ancient Greeks such as Aristotle more than 2,000 years ago. Late in the 16th century, the Italian scientist and writer Giambattista della Porta demonstrated and described in detail the use of a camera obscura with a lens. While artists in subsequent centuries commonly used variations on the camera obscura to create images they could trace, the results from these devices depended on the artist’s drawing skills, and so scientists continued to search for a method to reproduce images completely mechanically.

In 1727 the German professor of anatomy Johann Heinrich Schulze proved that the darkening of silver salts, a phenomenon known since the 16th century and possibly earlier, was caused by light and not heat. He demonstrated the fact by using sunlight to record words on the salts, but he made no attempt to preserve the images permanently. His discovery, in combination with the camera obscura, provided the basic technology necessary for photography. It was not until the early 19th century, however, that photography actually came into being.
Inventing the medium » Early experiments » Heliography

Nicéphore Niépce, an amateur inventor living near Chalon-sur-Saône, a city 189 miles (304 km) southeast of Paris, was interested in lithography, a process in which drawings are copied or drawn by hand onto lithographic stone and then printed in ink. Not artistically trained, Niépce devised a method by which light could draw the pictures he needed. He oiled an engraving to make it transparent and then placed it on a plate coated with a light-sensitive solution of bitumen of Judea (a type of asphalt) and lavender oil and exposed the setup to sunlight. After a few hours, the solution under the light areas of the engraving hardened, while that under the dark areas remained soft and could be washed away, leaving a permanent, accurate copy of the engraving. Calling the process heliography (“sun drawing”), Niépce succeeded from 1822 onward in copying oiled engravings onto lithographic stone, glass, and zinc and from 1826 onto pewter plates.

In 1826/27, using a camera obscura fitted with a pewter plate, Niépce produced the first successful photograph from nature, a view of the courtyard of his country estate, Gras, from an upper window of the house. The exposure time was about eight hours, during which the sun moved from east to west so that it appears to shine on both sides of the building.

Niépce produced his most successful copy of an engraving, a portrait of Cardinal d’Amboise, in 1826. It was exposed in about three hours, and in February 1827 he had the pewter plate etched to form a printing plate and had two prints pulled. Paper prints were the final aim of Niépce’s heliographic process, yet all his other attempts, whether made by using a camera or by means of engravings, were underexposed and too weak to be etched. Nevertheless, Niépce’s discoveries showed the path that others were to follow with more success.
Inventing the medium » Early experiments » Daguerreotype

Louis-Jacques-Mandé Daguerre was a professional scene painter for the theatre. Between 1822 and 1839 he was coproprietor of the Diorama in Paris, an auditorium in which he and his partner Charles-Marie Bouton displayed immense paintings, 45.5 by 71.5 feet (14 by 22 metres) in size, of famous places and historical events. The partners painted the scenes on translucent paper or muslin and, by the careful use of changing lighting effects, were able to present vividly realistic tableaux. The views provided grand, illusionistic entertainment, and the amazing trompe l’oeil effect was purposely heightened by the accompaniment of appropriate music and the positioning of real objects, animals, or people in front of the painted scenery.

Still Life, daguerreotype by Louis-Jacques-Mandé Daguerre, 1837; …[Credits : Collection de la Société Francaiçe de Photographie, Paris]Like many other artists of his time, Daguerre made preliminary sketches by tracing the images produced by both the camera obscura and the camera lucida, a prism-fitted instrument that was invented in 1807. His attempt to retain the duplication of nature he perceived in the camera obscura’s ground glass led in 1829 to a partnership with Niépce, with whom he worked in person and by correspondence for the next four years. However, Daguerre’s interest was in shortening the exposure time necessary to obtain an image of the real world, while Niépce remained interested in producing reproducible plates. It appears that by 1835, three years after Niépce’s death, Daguerre had discovered that a latent image forms on a plate of iodized silver and that it can be “developed” and made visible by exposure to mercury vapour, which settles on the exposed parts of the image. Exposure times could thus be reduced from eight hours to 30 minutes. The results were not permanent, however; when the developed picture was exposed to light, the unexposed areas of silver darkened until the image was no longer visible. By 1837 Daguerre was able to fix the image permanently by using a solution of table salt to dissolve the unexposed silver iodide. That year he produced a photograph of his studio on a silvered copper plate, a photograph that was remarkable for its fidelity and detail. Also that year, Niépce’s son Isidore signed an agreement with Daguerre affirming Daguerre as the inventor of a new process, “the daguerreotype.”

In 1839 Niépce’s son and Daguerre sold full rights to the daguerreotype and the heliograph to the French government, in return for annuities for life. On August 19 full working details were published. Daguerre wrote a booklet describing the process, An Historical and Descriptive Account of the Various Processes of the Daguerreotype and the Diorama, which at once became a best seller; 29 editions and translations appeared before the end of 1839.
Inventing the medium » Early experiments » Photogenic drawing

The antecedents of photogenic drawing can be traced back to 1802, when Thomas Wedgwood, son of the famous potter Josiah Wedgwood, reported his experiments in recording images on paper or leather sensitized with silver nitrate. He could record silhouettes of objects placed on the paper, but he was not able to make them permanent. Sir Humphry Davy published a paper in the Journal of the Royal Institution, London, in June 1802, on the experiments of his friend Wedgwood; this was the first account of an attempt to produce photographs.

In 1833 the French-born photographer Hercules Florence worked with paper sensitized with silver salts to produce prints of drawings; he called this process “photography.” However, since he conducted his experiments in Brazil, apart from the major scientific centres of the time, his contributions were lost to history until 1973, when they were rediscovered. Others in Europe, including one woman, claimed to have discovered similar photographic processes, but no verifiable proof has come to light.

William Henry Fox Talbot, trained as a scientist at the University of Cambridge, could not draw his scientific observations, even with the aid of a camera lucida; this deficiency inspired him to invent a photographic process. He decided to try to record by chemical means the images he observed, and by 1835 he had a workable technique. He made paper light-sensitive by soaking it alternately in solutions of common salt (sodium chloride) and silver nitrate. Silver chloride was thus produced in the fibres of the paper. Upon exposure to light, the silver chloride became finely divided silver, dark in tone. Theoretically, the resulting negative, in which tonal and spatial values were reversed, could be used to make any number of positives simply by putting fresh sensitized paper in contact with the negative and exposing it to light. Talbot’s method of fixing the print by washing it in a strong solution of sodium chloride was inadequate, however, and the process was not successful until February 1839, when his astronomer friend Sir John Herschel suggested fixing the negatives with sodium hyposulphite (now called sodium thiosulfate) and waxing them before printing, which reduced the grain of the paper.

When news of Daguerre’s process reached England in January 1839, Talbot rushed publication of his “photogenic drawing” process and subsequently explained his technique in complete detail to the members of the Royal Society—six months before the French government divulged working directions for the daguerreotype.
Inventing the medium » Early views of the medium’s potential

Photography’s remarkable ability to record a seemingly inexhaustible amount of detail was marveled at again and again. Still, from its beginnings, photography was compared—often unfavourably—with painting and drawing, largely because no other standards of picture making existed. Many were disappointed by the inability of the first processes to record colours and by the harshness of the tonal scale. Critics also pointed out that moving objects were not recorded or were rendered blurry and indistinct because of the great length of time required for an exposure.

Despite these deficiencies, many saw the technique of photography as a shortcut to art. No longer was it necessary to spend years in art school drawing from sculpture and from life, mastering the laws of linear perspective and chiaroscuro. Others saw these realizations as threatening. For example, upon first seeing the daguerreotype process demonstrated, the academic painter Paul Delaroche declared, “From today, painting is dead”; although he would later realize that the invention could actually aid artists, Delaroche’s initial reaction was indicative of that of many of his contemporaries. Such artists at first feared what Daguerre boasted in a 1838 broadsheet: “With this technique, without any knowledge of chemistry or physics, one will be able to make in a few minutes the most detailed views.”
Photography’s early evolution, c. 1840–c. 1900 » The revolution of technique » Development of the daguerreotype

Daguerre’s process rapidly spread throughout the world. Before the end of 1839, travelers were buying daguerreotypes of famous monuments in Egypt, Israel, Greece, and Spain; engravings of these works were made and then published in two volumes as Excursions daguerriennes between 1841 and 1843. Although Daguerre’s process was published “free to the world” by the French government, he took out a patent for it in England; the first licensee was Antoine-François-Jean Claudet. The first daguerreotypes in the United States were made on September 16, 1839, just four weeks after the announcement of the process. Exposures were at first of excessive length, sometimes up to an hour. At such lengthy exposures, moving objects could not be recorded, and portraiture was impractical.

Experiments were begun in Europe and the United States to improve the optical, chemical, and practical aspects of the daguerreotype process to make it more feasible for portraiture, the most desired application. The earliest known photography studio anywhere opened in New York City in March 1840, when Alexander Wolcott opened a “Daguerrean Parlor” for tiny portraits, using a camera with a mirror substituted for the lens. During this same period, József Petzval and Friedrich Voigtländer, both of Vienna, worked on better lens and camera design. Petzval produced an achromatic portrait lens that was about 20 times faster than the simple meniscus lens the Parisian opticians Charles Chevalier and N.M.P. Lerebours had made for Daguerre’s cameras. Meanwhile, Voigtländer reduced Daguerre’s clumsy wooden box to easily transportable proportions for the traveler. These valuable improvements were introduced by Voigtländer in January 1841. That same month another Viennese, Franz Kratochwila, freely published a chemical acceleration process in which the combined vapours of chlorine and bromine increased the sensitivity of the plate by five times.

The first studio in Europe was opened by Richard Beard in a glasshouse on the roof of the Royal Polytechnic Institution in London on March 23, 1841. Unlike the many daguerreotypists who were originally scientists or miniature painters, Beard had been a coal merchant and patent speculator. Having acquired the exclusive British license for the American mirror camera (he later also purchased the exclusive rights to Daguerre’s invention in England, Wales, and the colonies), Beard employed the chemist John Frederick Goddard to try to improve and accelerate the exposure process. Among the techniques Goddard studied were two that Wolcott had tried: increasing the light sensitivity of the silver iodide with bromine vapours and filtering the blindingly bright daylight necessary for exposure through blue glass to ease the portrait sitter’s eye strain. By December 1840 Goddard had succeeded well enough to produce tiny portraits ranging in size from 0.4 inch (1 cm) in diameter to 1.5 by 2.5 inches (4 by 6 cm). By the time Beard opened his studio, exposure times were said to vary between one and three minutes according to weather and time of day. His daguerreotype portraits became immensely popular, and the studio made considerable profits the first few years, but competition soon appeared, and Beard lost his fortune in several lawsuits against infringers of his licenses.

The finest daguerreotypes in Britain were produced by Claudet, who opened a studio on the roof of the Royal Adelaide Gallery in June 1841. He was responsible for numerous improvements in photography, including the discovery that red light did not affect sensitive plates and could therefore be used safely in the darkroom. The improvements that had been made in lenses and sensitizing techniques reduced exposure times to approximately 20 to 40 seconds.

Daguerreotyping became a flourishing industry. Practitioners such as Hermann Biow and Carl Ferdinand Stelzner worked in Germany, and William Horn opened a studio in Bohemia in 1841. It was the United States, however, that led the world in the production of daguerreotypes. Portraiture became the most popular genre in the United States, and within this genre, standards of presentation began to develop. Certain parts of the daguerreotype portrait, usually the lips, eyes, jewelry, and occasionally the clothing, were hand-coloured, a job often done by women. Because of their fragile nature, daguerreotype images always were covered with glass and encased in a frame or casing made of leather-covered wood or gutta-percha, a plasticlike substance made from rubber.

In the late 1840s every city in the United States had its own “daguerrean artist,” and villages and towns were served by traveling photographers who had fitted up wagons as studios. In New York City alone there were 77 galleries in 1850. Of these, the most celebrated was that of Mathew B. Brady, who began in 1844 to form a “Gallery of Illustrious Americans,” a collection of portraits of notables taken by his own and other cameramen. Several of these portraits, including those of Daniel Webster and Edgar Allen Poe, were published by lithography in a folio volume.

In Boston, Albert Sands Southworth and Josiah Johnson Hawes opened a studio in 1843 that was advertised as “The Artists’ Daguerreotype Rooms”; here they produced the finest portraits ever made by the daguerreotype process. The partners avoided the stereotyped lighting and stiff posing formulas of the average daguerreotypist and did not hesitate to portray their sitters unprettified and “as they were.” For example, in his portrait Lemuel Shaw, a judge of the Supreme Court of Massachusetts, stands with a crumpled coat and unruly locks of hair under a glare of sunshine; in her portrait Lola Montez—adventurer, dancer, actress—lolls over the back of a chair, a cigarette between her gloved fingers.

Cities and towns, as well as their inhabitants, were also photographed by American daguerreotypists: the rapid growth of San Francisco was documented month by month, and the first history of the city, published in 1855, was illustrated with engravings made from daguerreotypes.

Daguerreotyping spread throughout the world during the 1850s as photographers from England, France, and the United States followed colonialist troops and administrators to the Middle East, Asia, and South America. Army personnel and commercial photographers portrayed foreign dignitaries, landscape, architecture, and monuments in order to show Westerners seemingly exotic cultures. Particularly notable were daguerreotypes made in Japan by the American photographer Eliphalet Brown, Jr., who accompanied the 1853–54 mission led by Matthew C. Perry to open Japan to Western interests.

While most of the initial photographic work in these places was by Westerners, by the 1860s local practitioners had begun to open studios and commercial establishments. Marc Ferrez in Brazil, Kusakabe Kimbei in Japan, the (French-born) Bonfils family in Lebanon, and Kassian Céphas in Indonesia were among the international photographers who set up studios to supply portraits and views during this period.
Photography’s early evolution, c. 1840–c. 1900 » The revolution of technique » Development of the calotype

The popularity of the daguerreotype surpassed that of the photogenic drawing, but Talbot, convinced of the value of duplicability, continued to work to improve his process. On September 21–23, 1840, while experimenting with gallic acid, a chemical he was informed would increase the sensitivity of his prepared paper, Talbot discovered that the acid could be used to develop a latent image. This discovery revolutionized photography on paper as it had revolutionized photography on metal in 1835. Whereas previously Talbot had needed a camera exposure of one hour to produce a 6.5-by-8.5-inch (16.5-by-21.6-cm) negative, he now found that one minute was sufficient. Developing the latent image made photography on paper as valued as the daguerreotype, although the image still was not as clearly defined. Talbot named his improved negative process the calotype, from the Greek meaning “beautiful picture,” and he protected his discoveries by patent.

Portrait of Two Men (John Henning and Alexander Handyside Ritchie), …[Credits : Courtesy of The Art Institute of Chicago, All Rights Reserved, The Alfred Stieglitz Collection, 1949.685]The first aesthetically satisfying use made of this improved process was in the work of David Octavius Hill, a Scottish landscape painter, and his partner, Robert Adamson, an Edinburgh photographer. In 1843 Hill decided to paint a group portrait of the ministers who in that year formed the Free Church of Scotland; in all, there were more than 400 figures to be painted. Sir David Brewster, who knew of Talbot’s process from the inventor himself, suggested to Hill that he make use of this new technique. Hill then enlisted the aid of Adamson, and together they made hundreds of photographs, not only of the members of the church meeting but also of people from all walks of life. Although their sitters were posed outdoors in glaring sunlight and had to endure exposures of upward of a minute, Hill and Adamson managed to retain a lifelike vitality. Hill’s aesthetic was dominated by the painting style of the period in lighting and posing, particularly in the placement of the hands; in many of Hill’s portraits, both the sitter’s hands are visible, placed in a manner meant to add grace and liveliness to a dark portion of an image. Indeed, many of his calotypes are strikingly reminiscent of canvases by Sir Henry Raeburn and other contemporary artists. Proving the calotype’s artistic qualities, William Etty, a royal academician, copied in oils the calotype Hill and Adamson made of him in 1844 and exhibited it as a self-portrait. In addition to their formal portraiture, the partners made a series of photographs of fishermen and their wives at Newhaven and in Edinburgh, as well as architectural studies.

The calotype, which lent itself to being manipulated by chemicals and paper, was used in the 1850s to create exceptionally artistic images of architectural monuments.
Photography’s early evolution, c. 1840–c. 1900 » The revolution of technique » Development of stereoscopic photography

Stereoscopic photographic views (stereographs) were immensely popular in the United States and Europe from about the mid-1850s through the early years of the 20th century. First described in 1832 by English physicist Sir Charles Wheatstone, stereoscopy was improved by Sir David Brewster in 1849. The production of the stereograph entailed making two images of the same subject, usually with a camera with two lenses placed 2.5 inches (6 cm) apart to simulate the position of the human eyes, and then mounting the positive prints side by side laterally on a stiff backing. Brewster devised a stereoscope through which the finished stereograph could be viewed; the stereoscope had two eye pieces through which the laterally mounted images, placed in a holder in front of the lenses, were viewed. The two images were brought together by the effort of the human brain to create an illusion of three-dimensionality.

Stereographs were made of a wide range of subjects, the most popular being views of landscapes and monuments and composed narrative scenes of a humorous or slightly suggestive nature. Stereoscopes were manufactured for various price ranges and tastes, from the simple hand-held device introduced by Oliver Wendell Holmes (who promoted stereography through articles in Atlantic Monthly) to elaborate floor models containing large numbers of images that could be flipped into place. The stereograph became especially popular after Queen Victoria expressed interest in it when it was exhibited at the 1851 Crystal Palace Exposition. Like television today, stereography during the second half of the 19th century was both an educational and a recreational device with considerable impact on public knowledge and taste.
Photography’s early evolution, c. 1840–c. 1900 » The revolution of technique » Development of the wet collodion process

Photography was revolutionized in 1851 by the introduction of the wet collodion process for making glass negatives. This new technique, invented by the English sculptor Frederick Scott Archer, was 20 times faster than all previous methods and was, moreover, free from patent restrictions. Paper prints could easily be made from glass-plate negatives. The process had one major drawback: the photographer had to sensitize the plate almost immediately before exposure and expose it and process it while the coating was moist. Collodion is a solution of nitrocellulose (guncotton) in alcohol and ether; when the solvents evaporate, a clear plasticlike film is formed. Since it is then impervious to water, the chemicals used for developing the exposed silver halides and removing the unexposed salts cannot penetrate the coating to act upon them. The wet collodion process was almost at once universally adopted because it rendered detail with great precision that rivaled that of the daguerreotype. It reigned supreme for more than 30 years and greatly increased the popularity of photography, despite the fact that it was unequally sensitive to different colours of the spectrum.

At first the positive prints made from the glass plate negatives were produced by Talbot’s salt paper method, but from the mid-1850s on they were made on albumen paper. Introduced in 1850 by Louis-Désiré Blanquart-Evrard, albumen paper is a slow printing-out paper (i.e., paper that produces a visible image on direct exposure, without chemical development) that had been coated with egg white before being sensitized. The egg white gave the paper a glossy surface that improved the definition of the image.

Uncut print from a carte-de-visite negative by …[Credits : George Eastman House Collection]A new style of portrait utilizing albumen paper, introduced in Paris by André-Adolphe-Eugène Disdéri in 1854, was universally popular in the 1860s. It came to be called the carte-de-visite because the size of the mounted albumen print (4 by 2.5 inches [10.2 by 6 cm]) corresponded to that of a calling card. Disdéri used a four-lens camera to produce eight negatives on a single glass plate. Each picture could be separately posed, or several exposures of the same pose could be made at once. The principal advantage of the system was its economy: to make eight portraits the photographer needed to sensitize only a single sheet of glass and make one print, which was then cut up into separate pictures. At first cartes-de-visite almost invariably showed the subjects standing. Over time, backgrounds became ornate: furniture and such architectural fragments as papier-mâché columns and arches were introduced, and heavy-fringed velvet drapes were hung within range of the camera. With the advent of the cabinet-size (6.5 by 4 inches [16.5 by 10.2 cm]) picture in 1866, the decorative strategies of the photographer became yet more pronounced, so that in 1871 a photographer wrote: “One good, plain background, disrobed of castles, piazzas, columns, curtains and what not, well worked, will suit every condition of life.”

The new wet collodion process was also used to produce positive images on glass called ambrotypes, which were simply underexposed or bleached negatives that appeared positive when placed against a dark coating or backing. In pose and lighting, these popular portraits were similar to daguerreotypes in sizes and were enclosed in similar types of cases. They did not approach the brilliancy of the daguerreotype, however.

Tintypes, first known as ferrotypes or melainotypes, were cheap variations of the ambrotype. Instead of being placed on glass, the collodion emulsion was coated on thin iron sheets that were enameled black. At first they were presented in cases, surrounded by narrow gilt frames, but by the 1860s this elaborate presentation had been abandoned, and the metal sheets were simply inserted in paper envelopes, each with a cutout window the size of the image. Easy to make and inexpensive to purchase, tintypes were popular among soldiers in the Civil War and remained a form of folk art throughout the 19th century. Poses of sitters in tintypes were often informal and sometimes humorous. Because they were cheap and easy to produce, tintypes became a popular form of street photography well into the 20th century. Street-corner photographers, often equipped with a donkey, were common in European countries.
Photography’s early evolution, c. 1840–c. 1900 » The revolution of technique » Photography of movement

Figure Hopping, series of photographs by Eadweard Muybridge, 1887; in the …[Credits : Courtesy of the Cooper—Hewitt Museum of Decorative Arts and Design, Smithsonian Institution]A few years before the introduction of the dry plate, the world was amazed by the photographs of horses taken by Eadweard Muybridge in California. To take these photographs, Muybridge used a series of 12 to 24 cameras arranged side by side opposite a reflecting screen. The shutters of the cameras were released by the breaking of their attached threads as the horse dashed by. Through this technique, Muybridge secured sets of sequential photographs of successive phases of the walk, the trot, and the gallop. When the pictures were published internationally in the popular and scientific press, they demonstrated that the positions of the animal’s legs differed from those in traditional hand-drawn representations. To prove that his photographs were accurate, Muybridge projected them upon a screen one after the other with a lantern-slide projector he had built for the purpose; the result was the world’s first motion-picture presentation. This memorable event took place at the San Francisco Art Association in 1880.

Muybridge, whose early studies were made with wet plates, continued his motion studies for some 20 years. With the new gelatin plates, he was able to improve his technique greatly, and in 1884–85, at the invitation of the University of Pennsylvania, he produced 781 sequential photographs of many kinds of animals as well as men and women engaged in a wide variety of activities. He was aided in this project by painter Thomas Eakins, who also made motion studies.

Muybridge’s photographic analysis of movement coincided with studies by French physiologist Étienne-Jules Marey to develop chronophotography. Whereas Muybridge had employed a battery of cameras to record detailed, separate images of successive stages of movement, Marey used only one, recording an entire sequence of movement on a single plate. With Marey’s method, the images of various phases of motion sometimes overlapped, but it was easier to see and understand the flow of movement. Marey was also able to record higher speeds at shorter intervals than Muybridge. Both his and Muybridge’s work greatly contributed to the field of motion study and to the development of the motion picture.
Photography’s early evolution, c. 1840–c. 1900 » The revolution of technique » Early attempts at colour

Photography’s transmutation of nature’s colours into various shades of black and white had been considered a drawback of the process from its inception. To remedy this, many portrait photographers employed artists who hand-tinted daguerreotypes and calotypes; artists also painted in oils over albumen portraits on canvas. Franz von Lenbach in Munich, for example, was among the many who projected onto canvas an image that had been made light-sensitive, whereupon he painted freely over it. In Japan, where hand-coloured woodcuts had a great tradition and labour was cheap, some firms from the 1870s onward sold photographs of scenic views and daily life that had been delicately hand-tinted. In the 1880s photochromes, colour prints made from hand-coloured photographs, became fashionable, and they remained popular until they were gradually replaced in the first decades of the 20th century by Autochrome plates.
Photography’s early evolution, c. 1840–c. 1900 » Establishing genres » Documentary photography » Landscape and architectural documentation

From the earliest days of the medium, landscape, architecture, and monuments were appealing subjects for photographers. This sort of photography, which was collected by artists, scientists, and travelers, was impelled by several factors. In Europe one powerful factor was the maneuverings among western European powers for control of portions of North Africa and Asia. From the late 1850s through the 1870s, British photographers were particularly active in recording the natural landscape and monuments of the empire’s domains: Francis Frith worked in Egypt and Asia Minor, producing three albums of well-composed images; Samuel Bourne photographed throughout India (with a retinue of equipment bearers); John Thomson produced a descriptive record of life and landscape in China; and French photographer Maxime Du Camp traveled to Egypt with Gustave Flaubert on a government commission to record landscape and monuments.

Both for patriotic reasons and as a commodity for travelers, photographers also were active in recording the landscape of western Europe in the 1850s and ’60s. Important British photographers included Roger Fenton, who worked in England and Wales; Charles Clifford, who worked in Spain; Robert Macpherson, who photographed Rome; and George Washington Wilson, who photographed Scotland. French photographer Adolphe Braun recorded the landscape around his native Alsace, as well as the mountainous terrain of the French Savoy, as did the brothers Louis-Auguste and Auguste-Rosalie Bisson. Herman Krone in Germany and Giacchino Altobelli and Carlo Ponti in Italy were also intent on recording the beauties of their regional landscapes.

Photographs of specific historical buildings were made for a number of purposes: to satisfy antiquarian curiosity, to provide information for restoration, to supply artists with material on which to base paintings, or to effect preservation efforts. Practically from photography’s inception, such documentation was commissioned by public and private authorities. In western Europe and the United States, photographs captured the building of the industrial infrastructure, from bridges to railroad lines, from opera houses to public places to monumental statuary. In the early 1850s Philip Henry Delamotte was hired to document the progress of the construction of the Crystal Place in London, and a few years later Robert Howlett depicted the building of the Great Eastern transatlantic steamship. Alfred and John Bool and Henry Dixon worked for the Society for Photographing Old London, recording historical buildings and relics. In the 1850s the French government commissioned several photographers to document historical buildings. Working with cameras making photographs as large as 20 by 29 inches (51 by 74 cm), Henri Le Secq, Charles Marville, and Charles Nègre produced remarkable calotypes of the cathedrals of Notre-Dame (Paris), Chartres, and Amiens, as well as other structures that were being restored after centuries of neglect. An establishment was set up in Lille, France, by Blanquart-Evrard at which these paper negatives could be printed in bulk.

O’Sullivan, 1873; in …[Credits : George Eastman House Collection]In the United States explorations of the lands beyond the Great Plains led to the apogee of landscape photography during the period. Before the Civil War, relatively few exceptional images of the Western landscape had been made. In the postwar era railroad companies and government commissions included photographers among their teams sent to determine mineral deposits, rights of way, and other conditions that would be suitable for settlement. Of the photographers confronting the spectacular landscape of the American West in the 1870s and ’80s, William Henry Jackson, O’Sullivan, and Carleton Watkins produced particularly notable work. Both O’Sullivan, who helped survey Nevada and New Mexico, and Watkins, who worked in California and Oregon, were able to convey through their work a sense of the untamed and extraordinary quality of the Western landscape. As a testament to the power of his images, Jackson’s photographs of the Grand Canyon and the Yellowstone River were influential in getting public land set aside for Yellowstone National Park. The work these and other photographers of the American West produced usually was made available in several sizes and formats, from stereographic images to mammoth-sized works.

Landscapes in places outside the United States and Europe were usually portrayed by European photographers during this period. However, exceptions included the Chinese photographer Afong Lai and the Brazilian photographer Marc Ferrez, both of whom produced excellent views of their native countries. In particular, Lai’s serene compositions reflected the conventions of the long-standing tradition of Chinese landscape painting.
Photography’s early evolution, c. 1840–c. 1900 » Establishing genres » Documentary photography » Social documentation

The recognition of the power of photography to persuade and inform led to a form of documentary photography known as social documentation, or social photography. The origins of the genre can be traced to the classic sociological study issued by Henry Mayhew in 1851, London Labour and the London Poor, although this was illustrated with drawings partly copied from daguerreotypes by Richard Beard and not actual photos. A later effort, Street Life in London (1877), by Adolphe Smith and John Thomson, included facsimile reproductions of Thomson’s photographs and produced a much more persuasive picture of life among London’s working class. Thomson’s images were reproduced by Woodburytype, a process that resulted in exact, permanent prints but was costly because it required hand mounting for each individual print. This pursuit was continued by John Barnardo, who, beginning in the 1870s, photographed homeless children in London for the purpose of both record keeping and fund-raising and thus fulfilled the double objectives of social documentation: capturing theoretically objective description and arousing sympathy. The “before” and “after” images used by Barnardo to demonstrate the efficacy of social intervention became a convention in social documentation. It was taken up to good effect by the Indian photographer Raja Lala Deen Dayal, especially in his documentation of the good works undertaken by the nizam of Hyderabad in the late 19th century. In 1877 Thomas Annan began a project in Edinburgh in which he used the camera to record the need for new housing for the working poor. He concentrated mainly on the derelict buildings and sewerage systems rather than on the inhabitants; eventually the images were collected for their artistic merit rather than their social use.

Baby in a Slum Tenement, photograph by Jacob A. Riis, 1888–89; in …[Credits : Library of Congress, Washington, D.C.]Social documentation became more focused in the work of Jacob A. Riis, a police reporter in New York City in the 1880s who spent about four years depicting slum life. Employing cameramen at first, Riis eventually learned the rudiments of the medium so that he could himself portray the living and working conditions of immigrants whose social circumstances, he believed, led to crime and dissolution. Reproduced by the recently developed halftone process, the photographs and drawings based on them illustrated How the Other Half Lives (1890), Riis’s first book about immigrant life. They also were turned into positive transparencies—slides—to illustrate Riis’s lectures, which were aimed at a largely middle-class audience, some of whom were said to have fainted at the sight of the conditions the images documented. Able to convince the progressive reformers of the time of the need for change, Riis’s work was instrumental in effecting slum-clearance projects in New York.

In European countries especially, there was also an awakened interest in documenting social customs during this period. Sometimes this meant recording those European customs that were being replaced by advancing industrialization. This interest led to the establishment of photographic archives, such as the National Photographic Record Association, set up in the mid-1890s by Benjamin Stone, a British member of Parliament. Left to the city of Birmingham, the collection included photographs taken by Stone and others of vanishing local customs. Other times this led to an interest in the particularities of dress and custom of those living in distant regions. William Carrick, a Scotsman, portrayed daily life in Russia. In addition to portraying nature and artifacts, John Thomson, Felice Beato, and Samuel Bourne also depicted indigenous peoples in China and India. In 1888 the journal National Geographic, which produced photographic accounts of cultures throughout the world, was established.
Photography’s early evolution, c. 1840–c. 1900 » Photography as art » Early developments

Photographic societies—made up of both professionals and amateurs enticed by the popularity of the collodion process—began to form in the mid-19th century, giving rise to the consideration of photography as an aesthetic medium. In 1853 the Photographic Society, parent of the present Royal Photographic Society, was formed in London, and in the following year the Société Française de Photographie was founded in Paris. Toward the end of the 19th century, similar societies appeared in German-speaking countries, eastern Europe, and India. Some were designed to promote photography generally, while others emphasized only artistic expression. Along with these organizations, journals promoting photography as art also appeared.

At the first meeting of the Photographic Society, the president, Sir Charles Eastlake (who was then also president of the Royal Academy), invited the miniature painter Sir William Newton to read the paper “Upon Photography in an Artistic View” (Journal of the Photographic Society, 1853). Newton’s argument was that photographs could be useful so long as they were taken “in accordance [as far as it is possible] with the acknowledged principles of Fine Art.” One way the photographer could make his results more like works of art, Newton suggested, was to throw the subject slightly out of focus. He also recommended liberal retouching. (Eastlake’s wife, Lady Eastlake, née Elizabeth Rigby, was one of the first to write lucidly about the artistic problems of collodion/albumen photography.)

In response to this desire to create photographs that would fit an established conception of what “art” should be, several photographers began to combine several negatives to make one print. These consisted of compositions that were considered too complicated to be photographed in a straightforward manner and thus pushed photography beyond its so-called mechanical capabilities. A famous example of this style was by O.G. Rejlander, a Swede who had studied art in Rome and was practicing photography in England. He joined 30 negatives to produce a 31-by-16-inch (79-by-41-cm) print entitled The Two Ways of Life (1857), an allegory showing the way of the blessed led through good works and the way of the damned through vice. Rejlander, who described the technique in detail in photographic journals, stated that his purpose was to prove to artists the aesthetic possibilities of photography, which they had generally denied. The photograph was shown in the Manchester Art Treasures Exhibition of 1857 and was purchased by Queen Victoria for Prince Albert.

Fading Away, composite photograph made from five negatives by Henry Peach Robinson, 1858; in …[Credits : George Eastman House Collection]Rejlander’s technique stimulated Henry Peach Robinson, a professional photographer who had been trained as an artist, to produce similar combination prints. He achieved fame with a five-negative print, Fading Away, produced in 1858. The subject, a dying girl, was considered by critics as too painful a subject to be represented by photography. Perhaps the implied authenticity of the camera bothered them, since painters had long presented subjects of a far more sensitive nature.

Robinson became an articulate member of the Photographic Society, and his teaching was even more influential than his photography. In 1869 the first of many editions and translations of his book, Pictorial Effect in Photography, was published. Robinson borrowed compositional formulas from a handbook on painting, claiming that use of them would bring artistic success. He stressed the importance of balance and the opposition of light against dark. At the core of his argument was the assumption that rules set up for one art form could be applied to another.

So long as photographers maintained that the way to photography as art was the emulation of painting, art critics were reluctant to admit the new medium to an independent aesthetic position. Portraits, when done as sensitively and as directly as those produced by Hill and Adamson, Nadar, and Cameron, won praise. But sentimental genre scenes, posed and arranged for the camera and lacking the truthfulness thought to be characteristic of photography, were the subject of considerable controversy. This debate would reach a crescendo at the end of the century.

Pond in Winter, photograph by Peter Henry Emerson, 1888; in the George Eastman House …[Credits : George Eastman House Collection]Opposing the strategies advocated by Robinson, in the 1880s the English physician and photographer Peter Henry Emerson proposed that photographs should reflect nature, offer “the illusion of truth,” and be produced without using retouching techniques, recombining multiple prints, or utilizing staged settings, models, and costumes. He believed that the unique qualities of tone, texture, and light inherent in photography made it a unique art form, making any embellishments used for the sake of “art” unnecessary. This is not to say his own photographs were purely documentary—in fact, his work in some ways mimicked the artistic effects of the Barbizon school and Impressionist painting—but they eschewed the manipulated artistic effects of his contemporaries. Emerson’s views, known as naturalistic photography, gained a considerable audience through his widely read 1889 publication entitled Naturalistic Photography and through numerous articles that appeared in photography journals throughout the 1890s.
Photography’s early evolution, c. 1840–c. 1900 » Photography as art » Pictorialism and the Linked Ring

The ideas of Newton, Rejlander, Robinson, and Emerson—while seemingly varied—all pursued the same goal: to gain acceptance for photography as a legitimate art form. These efforts to gain acceptance were all encompassed within Pictorialism, a movement that had been afoot for some time and that crystallized in the 1890s and early 1900s, when it was promoted through a series of international exhibiting groups. In 1892 the Brotherhood of the Linked Ring was founded in Britain by Robinson, George Davison, a leader of the Art Nouveau movement, and others dissatisfied with the scientific bias of the London Photographic Society. The group held annual exhibitions, which they called salons. While the members’ work varied from naturalism to staged scenes to manipulated prints, by the turn of the century it was their united belief that “through the Salon the Linked Ring has clearly demonstrated that pictorial photography is able to stand alone and that it has a future entirely apart from that which is purely mechanical.” Similar Pictorialist groups formed in other countries. These included the Photo-Club of Paris, the Trifolium of Austria, and like associations in Germany and Italy. Unity of purpose enabled members to exchange ideas and images with those who had similar outlooks in other countries.

Perfecting the medium, c. 1900–c. 1945 » The Photo-Secession

The Steerage, photogravure by Alfred Stieglitz, 1907; in the Art …[Credits : Courtesy of The Art Institute of Chicago, All Rights Reserved, Alfred Stieglitz Collection, 1949.847]At the turn of the 20th century, one of the most influential Pictorialist groups was the Photo-Secession, founded in New York City in 1902 by photographer Alfred Stieglitz. The Secession’s name was taken from the avant-garde secessionist movements in Europe that sought to differentiate themselves from what they considered outmoded ways of working and thinking about the arts. With the help of Edward Steichen, Stieglitz opened the Little Galleries of the Photo-Secession—popularly known as “291” after its address on Fifth Avenue—which exhibited the work of Modernist painters and sculptors as well as that of photographers who used a wide variety of printing processes, including gum-bichromate and bromoil printing. These procedures required considerable handwork and resulted in one-of-a-kind prints that in their softening effects resembled etchings or lithographs rather than photographs. Among the members of the Photo-Secession were Steichen, Alvin Langdon Coburn, Gertrude Käsebier, and Clarence H. White. Between 1903 and 1917 Stieglitz published 50 issues of the beautifully printed journal Camera Work, which contained, among other works, fine gravure reproductions of American and European photographs and halftone reproductions of artwork by Henri Matisse and Pablo Picasso.

This photograph …[Credits : Copyright 1971, Aperture Foundation, Inc., Paul Strand Archive]Over the 15-year period of the Photo-Secession’s existence, the outlook of Stieglitz and individual members changed, reflecting the general move away from the more artificial aspects of Pictorialism as the 20th century began. Increasingly, photographers wanted their work to look like photographs, not paintings, and valued the qualities that were unique to photography. Over time, 291 began to show more painting than photography, and, as Stieglitz became even more convinced of the value of “straight,” rather than manipulated, photographic printing, several original adherents fell away, among them Käsebier and White. The final two issues of Camera Work were devoted to “straight” work by Paul Strand, who was the only photographer Stieglitz considered promising at the time. Strand’s images, consisting mainly of New York views and close-up portraits (made with a 45-degree prism lens so that the subject was unaware of being photographed), combined pure formal qualities, such as beautiful tone and sharp focus, with intense feeling.
Perfecting the medium, c. 1900–c. 1945 » Colour photography

The Autochrome process, introduced in France in 1907 by Auguste and Louis Lumière, was the first practical colour photography process. It used a colour screen (a glass plate covered with grains of starch dyed to act as primary-colour filters and black dust that blocked all unfiltered light) coated with a thin film of panchromatic (i.e., sensitive to all colours) emulsion, and it resulted in a positive colour transparency. Because Autochrome was a colour transparency and could be viewed only by reflected light, however, researchers continued to look for improvements and alternative colour processes.

In 1935 Leopold Godowsky, Jr., and Leopold Mannes, two American musicians working with the Kodak Research Laboratories, initiated the modern era of colour photography with their invention of Kodachrome film. With this reversal (slide) film, colour transparencies could be obtained that were suitable both for projection and for reproduction. A year later the Agfa Company of Germany developed the Agfacolor negative-positive process, but owing to World War II the film did not become available until 1949. Meanwhile, in 1942 Kodak introduced the Kodacolor negative-positive film that 20 years later—after many improvements in quality and speed and a great reduction in price—would become the most popular film used for amateur photography.
Contemporary photography, c. 1945–present » Postwar developments

With the improvement in colour materials and processes, photographers became more interested in its creative possibilities. Beginning in the 1940s, American photographer Eliot Porter produced subtle studies of birds and nature in which colour allowed him to render an unparalleled level of nuance. Appreciated for both their scientific and their aesthetic value, these photographs embodied the potential of colour. Austrian photojournalist Ernst Haas first used colour in the photo-essay New York for Life magazine in 1953. Through this and similar projects he challenged the standard of using only black and white in photojournalism, and his use of colour added vibrancy to images of everyday life. While these and other experiments achieved some success, it was not until later in the century that colour dominated photographic output and was incorporated into daily newspapers.

In the period after World War II, as the United States entered a period of domestic peace and prosperity, many photographers there moved away from documentary realities and focused instead on the intrinsic qualities of photography; such experiments paralleled the ascendancy of the Abstract Expressionist art movement, which similarly looked at the intrinsic quality of painting. Minor White combined ideas about photography’s incomparable descriptive power, taken from Edward Weston, with those about its emotional expressiveness, taken from Alfred Stieglitz. Through his long career as an influential teacher and founding editor of Aperture, White developed the idea that a photograph should contain an inner message that might not be immediately visible on the surface.

Other American photographers influenced by the Abstract Expressionist style of the era included Aaron Siskind, who found formal configurations in graffiti, weathered wood and plaster, and torn billboards (what he called the “detritus of the world”), and Harry Callahan, whose work demonstrated a highly developed sense of linear form. Siskind and Callahan inspired a generation of young photographers through their teachings at the Institute of Design, the school that had been started in 1937 in Chicago by Moholy-Nagy as the New Bauhaus. Barbara Crane, Ken Josephson, and Gary Winogrand were among students who later achieved fame. In England Bill Brandt created expressive photographs of nudes, shooting his subject matter at such close range that the human body took on the appearance of series of patterns and abstract designs. In Germany Otto Steinert led the Fotoform group of photographers, who created close-up views of nature that were also nearly abstract in their effects.

By the 1960s similar styles and ideas in photography had spread to Asia, in part because photographic magazines became widely available. Japanese photographers had been aware of Modernist currents before World War II, but afterward they pursued them more openly. Among the important photographers of this generation were Shōmei Tomatsu, who made vivid images on the streets of Tokyo; Eikō Hosoe, who captured imagery evoking human sensuality; and Hiroshi Sugimoto, who was entranced by images conveying stillness and emptiness. For a period the government in China exerted control over photographic imagery, but by the late 20th century photographers had found some freedoms. Chen Changfen was able to indulge his interest in colour abstractions, and Xie Hailong produced photographic documentations of problems in contemporary Chinese society, such as the difficulties faced by rural students seeking an education.

Untitled (New York City), gelatin silver print by Helen Levitt, c. 1942; …[Credits : Courtesy of The Art Institute of Chicago, All Rights Reserved, Restricted gift of Lucia Woods Lindley and Daniel A. Lindley, Jr., 1987.382]Street photography might be considered a special aspect of documentation: the street photographer is intrigued by the serendipitous nature of street activity, but, in contrast to the social documentarian, the street photographer does not necessarily have a social purpose in mind. Important street photographers included Helen Levitt, who documented subjects such as underprivileged children and young African Americans. All her work was infused with a compelling sense of immediacy. Levitt was following the steps of Cartier-Bresson, Brassaï, and André Kertész—the best known of the many European photographers of the 1930’s–’50s who used their small cameras to capture the vitality of urban life. Roy DeCarava documented his native Harlem and the civil rights movement; he said that he strove for “a creative expression, the kind of penetrating insight and understanding of Negroes which I believe only a Negro photographer can interpret.” This kind of street photography, made possible by the increasing availability of light portable cameras with fast-acting mechanisms, appealed to photographers around the world. Indian photographer Raghubir Singh, who worked in colour, sought to reveal both the inner and outer life of his people through his street photography.

Other social documentation in the postwar period used the medium to examine contemporary society from a distance. Such efforts had various labels, including “social landscape.” Inspired by Swiss-born émigré Robert Frank, who during the 1950s viewed American culture with an ironic eye, American photographers such as Bruce Davidson, Lee Friedlander, and William Klein were among those whose work suggested the effects of contemporary culture on people in industrialized societies. Often utilizing 35-mm cameras, these photographers caught seeming mundane everyday moments in works that resembled snapshots. Beneath this seeming spontaneity lay an element of critique, however, that in some cases paralleled Pop art’s examination of the banality of contemporary consumer culture.

Several important photographers defied categorization. In the early 1960s the photographer Sedou Keïta, working as a commercial portraitist in Mali, allowed his sitters to arrange and costume themselves. The resulting photographs created an extensive and compelling documentation of his country’s people. In the same period, influenced by the mordant eye of the earlier Austrian émigré photographer Lisette Model, Diane Arbus created challenging portraits of people living outside prescribed ideas of “normalcy,” such as transvestites and the mentally ill.
Contemporary photography, c. 1945–present » Developments from the 1970s to the present

Continuing the example set by Arbus, a gritty sort of social documentation emerged beginning in the 1970s and ’80s, when photographers such as Larry Clark and Nan Goldin documented alternative lifestyles involving drug addiction, transvestism, and casual sex. In particular, Goldin created an elaborate series entitled The Ballad of Sexual Dependency, sometimes accompanied by music and spoken work, through which she created an evolving record of the people she and her camera encountered. Such direct, unflinching photographs established intimate documentary work as an important genre in the late 20th century. Photographers such as Sally Mann and Tina Barney extended this genre to portray intimate, sometimes unsettling images of their own families.

Goldin and Clark both usually photographed in colour, which added to the harsh sense of reality in their work; this represented a general move toward colour among photographers of their generation. William Eggleston pushed the artistic boundaries of colour by using it to explore the banality of small-town existence; along these same lines, Candida Höfer used colour to emphasize the tedium of institutional life. Richard Misrach created a massive project, known as the Desert Cantos, in which he photographed desert scenes in colour, sometimes juxtaposed against sinister elements such as nuclear sites. Barbara Norfleet, Joel Meyerowitz, Stephen Shore, Barbara Kasten, and Franco Fontana were among the other prominent photographers of the period who used colour expressively in landscapes, interiors, still lifes, and street scenes.

From the 1970s on, as the advent of television news began to affect the popularity of picture magazines, many photojournalists whose work had been published in magazines began to take advantage of a burgeoning interest in photographic picture books. These, often produced in conjunction with exhibits, comprised photographs of newsworthy events or topics of social interest along with informative texts. Working in black and white, Swiss-born photographer Claudia Andujar (working in Brazil) and Mexican photographer Graciela Iturbide portrayed indigenous peoples—groups they believed were becoming marginalized by society—and their customs. Other important figures included English photographer Don McCullin, who portrayed the devastation brought about by wars in Vietnam and in Africa; French photojournalist Raymond Depardon, who worked in Asia, Africa, and Europe; American Mary Ellen Mark, who photographed street performers and prostitutes in India, depicted street children in Seattle, Washington, and spent time documenting the inmates of a mental hospital; and Brazilian photographer Sebastião Salgado, who examined work and workers throughout the world, exhibiting and publishing a number of books on that topic. For his ability to make world events come pictorially alive, American James Nachtwey was three times the winner of the International Center of Photography’s photojournalism awards. By the end of the century, the technology used by these photojournalists had changed. Digital cameras sent images directly to computers, and programs allowed images to be altered seamlessly, making newspaper and magazine darkrooms obsolete.

The documentation of artifacts, begun in the 19th century, continued to interest late 20th-century photographers. Italian photographer Gabriele Basilico and American photographer Lewis Baltz concentrated on architecture and the built environment. The German duo Bernd and Hilla Becher produced an extensive portrayal of industrial buildings such as mine tipples and factories, which they usually displayed in carefully planned arrangements of multiple prints. This sort of project combined traditional documentary conventions with postmodern concepts about typologies.

Fashion photographers found their role redefined at the end of the century. As giants of fashion photography from earlier in the century such as Irving Penn and Richard Avedon became the subjects of major museum retrospectives, fashion and celebrity photography, initially meant to illustrate fashion magazines such as Harper’s Bazaar and Vogue, became fully recognized as an art form. Photographers David LaChapelle, Annie Leibovitz, Helmut Newton, Mario Testino, and Bruce Weber were among those whose work was esteemed enough to be exhibited in both gallery and museum shows and published in popular monographs.

Throughout most of the 20th century, the art world was dominated by painting and sculpture, with photography seen as a separate but not necessarily equal art form. In the 1980s and ’90s, however, as new media such as video, performance, and installation blurred definitions of “art,” photography became one of the art world’s most prominent media. During this period a generation of prominent photographers, many of them American, helped break down these barriers between photography and “art.” American Robert Mapplethorpe received a maelstrom of attention for his masterfully executed photographs, which ranged from still lifes to portraits to, most controversially, sadomasochistic and homoerotic themes. American photographer Cindy Sherman became an international art star for her elaborately staged self-portraits in which she posed in a variety of stereotypical feminine roles and, in so doing, critiqued these clichés. Barbara Kruger, also American, gained prominence for her modern-day montages, in which she juxtaposed photographic images with text containing social critique—perhaps most famously, the phrases “I Shop, Therefore I Am” and “Your Body Is a Battleground.” A similar use of photography in mixed-media was pursued by American Carrie Mae Weems, who reproduced 19th-century photographs of slaves on a series of banners and scrims, presenting them in a three-dimensional arrangement that commented on the visual representation of African Americans throughout history.

At the turn of the 21st century, the wizardry made possible by digital capabilities was reflected in the work of a prominent new generation of international photographers. Most of these photographers worked almost exclusively in colour; indeed, at the turn of the century, black-and-white prints of contemporary photographic work were the exception rather than the rule, as new computer programs made possible a vast array of colours, many of which may not have existed at the time of the actual exposure. Computers also allowed photographers to combine their photographs with other digitally captured or scanned images and to make works on an unprecedented scale. Major figures at the turn of the century, all of whom worked on a large scale, included German photographer Andreas Gursky, known for his detached views of spaces such as stock exchanges and government buildings; German photographer Thomas Struth, whose work dispassionately captured the interiors of museum galleries; Japanese photographer Mariko Mori, who featured herself as a character in candy-coloured futuristic landscapes; and British photographer Sam Taylor-Wood, who created panoramic scenes of interiors filled with bored, isolated-seeming subjects. Exhibited in venues formerly reserved for painting, and at times along with paintings, monumental photographs by this new generation of photographers effectively ushered in a new era of possibility for the medium.
