History of Photography

The word photography derives from the Greek words photos, light, and graphein, to write. The word was coined by Sir John Herschel in 1839.

Photography is the result of combining several technical discoveries. Long before the first photographs were made, Chinese philosopher Mo Ti and Greek philosophers such as Aristotle and Euclid described a pinhole camera in the 5th and 4th centuries B.C.E,Ibn al-Haytham (Alhazen) (965–1040) studied the camera obscura and pinhole camera,Albertus Magnus (1193/1206-1280) discovered silver nitrate, and Georges Fabricius (1516–1571) discovered silver chloride. Daniel Barbaro described a diaphragm in 1568. Wilhelm Homberg described how light darkened some chemicals (photochemical effect) in 1694. The novel Giphantie (by the French Tiphaigne de la Roche, 1729–1774) described what can be interpreted as photography.

For years images have been projected onto surfaces. According to the Hockney–Falco thesis as argued by artist David Hockney, some artists used the camera obscura and camera lucida to trace scenes as early as the 16th century. However, this theory is heavily disputed by today’s contemporary realist artists who are able to create high levels of realism without optical aids. These early cameras did not record an image, but only projected images from an opening in the wall of a darkened room onto a surface, turning the room into a large pinhole camera. The phrase camera obscura literally means dark chamber. While this early prototype of today’s modern camera may have had modest usage in its time, it was an important step in the evolution of the invention.

Development of chemical photography

Monochrome process

Nicéphore Niépce’s earliest surviving photograph of a scene from nature, circa 1826, “View from the Window at Le Gras,” Saint-Loup-de-Varennes (France).

“Boulevard du Temple”, taken by Louis Daguerre in late 1838 or early 1839, was the first-ever photograph of a person. It is an image of a busy street, but because exposure time was over ten minutes, the city traffic was moving too much to appear. The exception is a man in the bottom left corner, who stood still getting his boots polished long enough to show up in the picture.

Robert Cornelius, self-portrait, Oct. or Nov. 1839, approximate quarter plate daguerreotype. The back reads, “The first light picture ever taken.” This self-portrait is the first photographic portrait image of a human ever produced.

The first permanent photograph (later accidentally destroyed) was an image produced in 1826 by the French inventor Joseph Nicéphore Niépce. His photographs were produced on a polished pewter plate covered with a petroleum derivative called bitumen of Judea. Bitumen hardens with exposure to light. The unhardened material may then be washed away and the metal plate polished, rendering a negative image which then may be coated with ink and impressed upon paper, producing a print. Niépce then began experimenting with silver compounds based on a Johann Heinrich Schultz discovery in 1724 that a silver and chalk mixture darkens when exposed to light.

In partnership, Niépce (in Chalon-sur-Saône) and Louis Daguerre (in Paris) refined the existing silver process. In 1833 Niépce died of a stroke, leaving his notes to Daguerre. While he had no scientific background, Daguerre made two pivotal contributions to the process. He discovered that exposing the silver first to iodine vapour before exposure to light, and then to mercury fumes after the photograph was taken, could form a latent image. Bathing the plate in a salt bath then fixes the image. On January 7, 1839 Daguerre announced that he had invented a process using silver on a copper plate called the daguerreotype. The French government bought the patent and immediately made it public domain.

In 1832, French-Brazilian painter and inventor Hercules Florence had already created a very similar process, naming it Photographie.

After reading about Daguerre’s invention, Fox Talbot worked on perfecting his own process; in 1839 he acquired a key improvement, an effective fixer, from John Herschel, the astronomer, who had previously showed that hyposulfite of soda (also known as hypo, or now sodium thiosulfate) would dissolve silver salts. Later that year, Herschel made the first glass negative.

By 1840, Talbot had invented the calotype process. He coated paper sheets with silver chloride to create an intermediate negative image. Unlike a daguerreotype, a calotype negative could be used to reproduce positive prints, like most chemical films do today. Talbot patented this process, which greatly limited its adoption. He spent the rest of his life in lawsuits defending the patent until he gave up on photography. Later George Eastman refined Talbot’s process, which 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. In 1847, 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 of Boston also invented workable negative-on-glass processes in the mid 1840s.

In 1851 Frederick Scott Archer invented the collodion process.^{[citation needed]} Photographer and children’s author Lewis Carroll used this process.^{[citation needed]}

Roger Fenton’s assistant seated on Fenton’s photographic van, Crimea, 1855.

Herbert Bowyer Berkeley experimented with his own version of collodian emulsions after Samman introduced the idea of adding dithionite to the pyrogallol developer.^{[citation needed]} 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.

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

Mid 19th century “Brady stand” photo model’s armrest table, meant to keep portrait models more still during long exposure times (studio equipment nicknamed after the famed US photographer, Mathew Brady).

The daguerreotype proved popular in responding to the demand for portraiture emerging from the middle classes during the Industrial Revolution.^{[citation needed]} This demand, that could not be met in volume and in cost by oil painting, added to the push for the development of photography.

In 1847, Count Sergei Lvovich Levitsky designed a bellows camera which significantly improved the process of focusing. This adaptation influenced the design of cameras for decades and is still found in use today in some professional cameras.^{[citation needed]}

While in Paris, Levitsky would become the first to introduce interchangeable decorative backgrounds in his photos, as well as the retouching of negatives to reduce or eliminate technical deficiencies.

Levitsky was also the first photographer to portray a photo of a person in different poses and even in different clothes (for example, the subject plays the piano and listens to himself).

By 1849, images captured by Levitsky on a mission to the Caucasus, were exhibited by the famous Parisian optician Chevalier at the Paris Exposition of the Second Republic as an advertisement of their lenses. These photos would receive the Exposition’s gold medal; the first time a prize of its kind had ever been awarded to a photograph.

That same year in 1849 in his St. Petersburg, Russia studio Levitsky would first propose the idea to artificially light subjects in a studio setting using electric lighting along with daylight. He would say of its use, “as far as I know this application of electric light has never been tried; it is something new, which will be accepted by photographers because of its simplicity and practicality”.

In 1851, at an exhibition in Paris, Levitsky would win the first ever gold medal awarded for a portrait photograph.

In America, by 1851 a broadside by daguerreotypist Augustus Washington were advertising prices ranging from 50 cents to $10. 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 modern 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.

In the twentieth century, photography developed rapidly as a commercial service. End-user supplies of photographic equipment accounted for only about 20 percent of industry revenue. For the modern enthusiast photographer processing black and white film, little has changed since the introduction of the 35mm film Leica camera in 1925.

The first digitally scanned photograph was produced in 1957. The digital scanning process was invented by Russell Kirsch, a computer pioneer at the National Institute of Standards and Technology. He developed the system capable of feeding a camera’s images into a computer. His first fed image was that of his son, Walden Kirsch. The photo was set at 176×176 pixels.

Color process

First color image, photograph by James Clerk Maxwell, 1861.

Although color photography was explored throughout the 19th century, initial experiments in color resulted in projected temporary images, rather than permanent color images. Moreover until the 1870s the emulsions available were not sensitive to red or green light.

The first color photo, an additive projected image of a tartan ribbon, was taken in 1861 by the Scottish physicist James Clerk Maxwell. Several patentable methods for producing images (by either additive or subtractive methods, see below) were devised from 1862 on by two French inventors (working independently), Louis Ducos du Hauron and Charles Cros. Practical methods to sensitize silver halide film to green and then orange light were discovered in 1873 and 1884 by Hermann W. Vogel, but full sensitivity to red light was not achieved until the early years of the 20th century.

The first fully practical color plate, Autochrome, did not reach the market until 1907. It was based on a screen-plate method, the screen (of filters) being made using dyed dots of potato starch. The screen lets filtered red, green or blue light through each grain to a photographic emulsion in contact with it. The plate is then developed to a negative, and reversed to a positive, which when viewed through the screen restores colors approximating the original.

Other systems of color photography included that used by Sergei Mikhailovich Prokudin-Gorskii, which involved three separate monochrome exposures (‘separation negatives’) of a still scene through red, green, and blue filters. These required a special machine to display, but the results are impressive even by modern standards. His collection of glass plates was purchased from his heirs by the Library of Congress in 1948, and is now available in digital images.

Development of digital photography

The charge-coupled device (CCD) was invented in 1969 by Willard Boyle and George E. Smith at AT&T Bell Labs. 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.

• 1973 – Fairchild Semiconductor releases the first large image forming CCD chip; 100 rows and 100 columns
• 1975 – Bryce Bayer of Kodak develops the Bayer filter mosaic pattern for CCD color image sensors
• 1986 – Kodak scientists develop the world’s first megapixel sensor.

My comment : Look how hard and photography ever created. Many people say that photography is very boring, but for those who want to learn and curious about these exciting fields, then that person will discover how beautiful the field of photography. People who say that photography is not fun is the people who are blind and need our help to open their eyes that photography is an exciting field where we can play with light, shutter speed, ISO, aperture, and others. Happy for those of you who’ve realized that photography is fun, then you are very appreciative of the inventors who have exhausted exhaust for nearly two centuries to create a field that is so beautiful and fun … ‘Photography’
