  1. COM 343: HISTORY OF PHOTOGRAPHY Lesson2: BEGINNINGS OF PHOTOGRAPHY Metin Ersoy Faculty of Communication and Media Studies

  2. HISTORY OF PHOTOGRAPHY • First, the name. We owe the name "Photography" to Sir John Herschel , who first used the term in 1839, the year the photographic process became public. • The word is derived from the Greek words for light and writing. HERSCHEL, Sir John Frederick William became interested in capturing and retaining images, and in 1839 had managed to fix pictures using hyposulphite of soda. In fact it was he who had discovered twenty years previously that hypo could dissolve silver salts.

  3. HISTORY OF PHOTOGRAPHY • There are two distinct scientific processes that combine to make photography possible. It is somewhat surprising that photography was not invented earlier than the 1830s, because these processes had been known for quite some time. • It was not until the two distinct scientific processes had been put together that photography came into being.

  4. HISTORY OF PHOTOGRAPHY • The first of these processes was optical. The Camera Obscura (dark room) had been in existence for at least four hundred years. • There is a drawing, dated 1519, of a Camera Obscura by Leonardo da Vinci; about this same period its use as an aid to drawing was being advocated.

  5. HISTORY OF PHOTOGRAPHY • The Camera Obscura (dark room)

  6. HISTORY OF PHOTOGRAPHY • The Camera Obscura (Latin for Dark room) was a dark box or room with a hole in one end. If the hole was small enough, an inverted image would be seen on the opposite wall. • Such a principle was known by thinkers as early as Aristotle (c. 300 BC). It is said that Roger Bacon invented the camera obscura just before the year 1300, but this has never been accepted by scholars; more plausible is the claim that he used one to observe solar eclipses.

  7. HISTORY OF PHOTOGRAPHY • In fact, the Arabian scholar Hassan ibn Hassan (also known as Ibn al Haitam), in the 10th century, described what can be called a camera obscura in his writings; manuscripts of his observations are to be found in the India Office Library in London.

  8. HISTORY OF PHOTOGRAPHY • The second process was chemical. For hundreds of years before photography was invented, people had been aware, for example, that some colours are bleached in the sun, but they had made little distinction between heat, air and light.

  9. HISTORY OF PHOTOGRAPHY • In the sixteen hundreds Robert Boyle, a founder of the Royal Society, had reported that silver chloride turned dark under exposure, but he appeared to believe that it was caused by exposure to the air, rather than to light. • Angelo Sala, in the early seventeenth century, noticed that powdered nitrate of silver is blackened by the sun.

  10. HISTORY OF PHOTOGRAPHY • In 1727 Johann Heinrich Schulze discovered that certain liquids change colour when exposed to light. Schulze was a German Professor at the University of Altdorf, whose experiments paved the way towards photography. Though it was known that certain chemicals darken when exposed to the sun, it was not clear whether it was the action of light or heat which had this effect. In 1727 Schulze heated some silver nitrate in an oven, and discovering that it did not darken was able to eliminate heat as the darkening agent.

  11. HISTORY OF PHOTOGRAPHY • Having noticed that a glass jar containing a particular chemical mixture changed colour on one side - that facing the window, he applied paper stencils to a bottle containing silver nitrate and chalk, discovering that where the substance was not exposed to light it remained white. • He published details of his investigations, but these did not become popular until after he had died.

  12. HISTORY OF PHOTOGRAPHY • At the beginning of the nineteenth century Thomas Wedgwood was conducting experiments; he had successfully captured images, but his silhouettes could not survive, as there was no known method of making the image permanent.

  13. HISTORY OF PHOTOGRAPHY • Thomas Wedgwood had worked closely with Davey, and their work was very nearly a breakthrough, for they had made what one can best describe as photograms. • However, they were unable to fix the images, and the story is told that Wedgwood was reduced to examining his pictures furtively by the light of a candle. They also tried using a camera obscura, but the chemicals being used at the time were not sufficiently sensitive.

  14. HISTORY OF PHOTOGRAPHY • The first successful picture was produced in June/July 1827 by Niépce, using material that hardened on exposure to light. This picture required an exposure of eight hours.

  15. HISTORY OF PHOTOGRAPHY • Niépce (pronounced Nee-ps) is universally credited with producing the first successful photograph in June/July 1827. He was fascinated with lithography, and worked on this process. • Unable to draw, he needed the help of his artist son to make the images. However, when in 1814 his son was drafted into the army to fight at Waterloo, he was left having to look for another way of obtaining images.

  16. HISTORY OF PHOTOGRAPHY This is the first known photograph. There is little merit in this picture other than that fact. It is difficult to decipher: the building is on the left, a tree a third in from the left, and a barn immediately in front. The exposure lasted eight hours, so the sun had time to move from east to west, appearing to shine on both sides of the building.

  17. HISTORY OF PHOTOGRAPHY • On 4 January 1829 Niépce agreed to go into partnership with Louis Daguerre . Niépce died only four years later, but Daguerre continued to experiment. Soon he had discovered a way of developing photographic plates, a process which greatly reduced the exposure time from eight hours down to half an hour. He also discovered that an image could be made permanent by immersing it in salt.

  18. HISTORY OF PHOTOGRAPHY • Daguerre (pronounced Dagair) was perhaps the most famous of several people who invented photography. • He regularly used a camera obscura as an aid to painting in perspective, • and this had led him to seek • to freeze the image. In 1826 he • learned of the work of • NicephoreNiépce, and on • 4 January 1829 signed up a • partnership with him.

  19. HISTORY OF PHOTOGRAPHY • The partnership was a short one, Niépce dying in 1833, but Daguerre continued to experiment. He made an important discovery by accident. In 1835, so the story goes, he put an exposed plate in his chemical cupboard, and some days later found, to his surprise, that the latent image had developed. • Daguerre eventually concluded that this was due to the presence of mercury vapour from a broken thermometer. This important discovery that a latent image could be developed made it possible to reduce the exposure time from some eight hours to thirty minutes.

  20. HISTORY OF PHOTOGRAPHY • Though he now knew how to produce an image, it was not until 1837 that he was able to fix them. This new process he called a Daguerreotype.

  21. HISTORY OF PHOTOGRAPHY • Following a report on this invention by Paul Delaroche , a leading scholar of the day, the French government bought the rights to it in July 1839. Details of the process were made public on 19 August 1839, and Daguerre named it the Daguerreotype.

  22. HISTORY OF PHOTOGRAPHY • The announcement that the Daguerreotype "requires no knowledge of drawing...." and that "anyone may succeed.... and perform as well as the author of the invention" was greeted with enormous interest, and "Daguerreomania" became a craze overnight. • An interesting account of these days is given by a writer called Gaudin, who was present the day that the announcement was made.

  23. HISTORY OF PHOTOGRAPHY • At that time some artists saw in photography a threat to their livelihood, and some even prophesied that painting would cease to exist.

  24. HISTORY OF PHOTOGRAPHY • The Daguerreotype process, though good, was expensive, and each picture was a once-only affair. That, to many, would not have been regarded as a disadvantage; it meant that the owner of the portrait could be certain that he had a piece of art that could not be duplicated. • If however two copies were required, the only way of coping with this was to use two cameras side by side. There was, therefore, a growing need for a means of copying pictures which daguerreotypes could never satisfy.

  25. HISTORY OF PHOTOGRAPHY • Different, and in a sense a rival to the Daguerreotype, was the Calotypeinvented by William Henry Fox Talbot , which was to provide the answer to that problem. • Calotype : The Calotype was a positive/negative process introduced in 1841 by Fox Talbot, and popular for the next ten years or so. Strictly speaking the term refers only to the negative image, but it is commonly taken to mean both.

  26. HISTORY OF PHOTOGRAPHY • A piece of paper was brushed with weak salt solution, dried, then brushed with a weak silver nitrate solution, dried, making silver chloride in the paper. This made it sensitive to light, and the paper was now ready for exposure. This might take half an hour, giving a print-out image. It was fixed in strong salt solution - potassium iodide of hypo. • Compared with Daguerreotypes the quality of the early Calotypes was somewhat inferior. However, the great advantage of Talbot's method was that an unlimited number of positive prints could be made. In fact, today's photography is based on the same principle, whereas by comparison the Daguerreotype, for all its quality, was a blind alley.

  27. HISTORY OF PHOTOGRAPHY • The mushrooming of photographic establishments reflects photography's growing popularity; from a mere handful in the mid 1840s the number had grown to 66 in 1855, and to 147 two years later.

  28. HISTORY OF PHOTOGRAPHY • Talbot's photography was on paper, and inevitably the imperfections of the paper were printed alongside with the image, when a positive was made. Several experimented with glass as a basis for negatives, but the problem was to make the silver solution stick to the shiny surface of the glass. • In 1848 a cousin of NicephoreNiépce, Abel Niépce de Saint-Victor, perfected a process of coating a glass plate with white of egg sensitised with potassium iodide, and washed with an acid solution of silver nitrate. This new ( albumen ) process made for very fine detail and much higher quality. However, it was very slow, hence the fact that photographs produced on this substance were architecture and landscapes; portraiture was simply not possible.

  29. HISTORY OF PHOTOGRAPHY • Progress in this new art was slow in England, compared with other countries. Both Daguerre and Fox Talbot were partly responsible, the former for having rather slyly placed a patent on his invention whilst the French government had made it freely available to the world, the latter for his law-suits in connection with his patents.

  30. HISTORY OF PHOTOGRAPHY • In 1851 a new era in photography was introduced by Frederick Scott Archer , who introduced the Collodion process. This process was much faster than conventional methods, reducing exposure times to two or three seconds, thus opening up new horizons in photography.

  31. HISTORY OF PHOTOGRAPHY • A further impetus was given to photography for the masses by the introduction of carte-de-visite photographs by Andre Disdéri . This developed into a mania, though it was relatively short-lived.

  32. HISTORY OF PHOTOGRAPHY • Different types of cameras were devised. Some had a mechanism which rotated the photographic plate, others had multiple lenses which could be uncovered singly or all together. • The carte-de-visite did not catch on until one day in May 1859 Napoleon III, on his way to Italy with his army, halted his troops and went into Disdéri's studio in Paris, to have his photograph taken. From this welcome publicity Disdéri's fame began, and two years later he was said to be earning nearly £50,000 a year from one studio alone.

  33. HISTORY OF PHOTOGRAPHY • The collodion process required that the coating, exposure and development of the image should be done whilst the plate was still wet. Another process developed by Archer was named the Ambrotype , which was a direct positive

  34. HISTORY OF PHOTOGRAPHY • The wet collodion process, though in its time a great step forward, required a considerable amount of equipment on location. There were various attempts to preserve exposed plates in wet collodion, for development at a more convenient time and place, but these preservatives lessened the sensitivity of the material. • It was clear, then, that a dry method was required. It is likely that the difficulties of the process hastened the search for instantaneous photography.

  35. HISTORY OF PHOTOGRAPHY • The next major step forward came in 1871, when Dr. Richard Maddox discovered a way of using Gelatin (which had been discovered only a few years before) instead of glass as a basis for the photographic plate. This led to the development of the dry plate process. • Dry plates could be developed much more quickly than with any previous technique. Initially it was very insensitive compared with existing processes, but it was refined to the extent that the idea of factory-made photographic material was now becoming possible.

  36. HISTORY OF PHOTOGRAPHY • The introduction of the dry-plate process marked a turning point. No longer did one need the cumbersome wet-plates, no longer was a darkroom tent needed. One was very near the day that pictures could be taken without the photographer needing any specialised knowledge. • Celluloid had been invented in the early eighteen-sixties, and John Carbutt persuaded a manufacturer to produce very thin celluloid as a backing for sensitive material. George Eastman is particularly remembered for introducing flexible film in 1884. Four years later he introduced the box camera, and photography could now reach a much greater number of people.

  37. HISTORY OF PHOTOGRAPHY • Other names of significance include Herman Vogel , who developed a means whereby film could become sensitive to green light, and Eadweard Muybridge who paved the way for motion picture photography. • Popular in the Victorian times was stereoscopic photography , which reproduced images in three dimensions. It is a process whose popularity waxed and waned - as it does now - reaching its heights in the mid-Victorian era.
