2. Heliography
Joseph Niepce’s Heliographs were taken using first pewter, then silver, plates coated with an emulsion made of bitumen of Judea and iodide fumes.

3. Daguerreotypes
Louis Daguerre realized that the silver iodide created by the fumes were themselves sensitive to light.
He also discovered that a latent image on the plate could be developed out by exposing the plate to mercury fumes.
He finally succeeded in fixing the image by soaking it in salt water to rinse out the remaining light sensitive silver iodide

4. Commercial Success
Their exquisite detail and relatively short sitting times (compared to a painting) made Daguerreotypes very popular with those wanting their portraits, or “likenesses”, made. The French government bought Daguerre’s process and gave it to the people as a gift. This allowed the Daguerreotype to become extremely popular and widely practiced.

6. Fox Talbot’s Calotype
William Henry Fox Talbot devised a way to create a negative image on a sheet of paper.
The advantage of the negative image was that, unlike the positive image created with a Daguerreotype, the Calotype, or Talbotype, could be reproduced as long as the original negative held up.

8. Albumen Printing
In 1844, Louis- Desire Blanquart- Evrard obtained Fox Talbot’s formula and rapidly made advancements in speed of exposure, ease of development and reliability.
Blanquart- Evrard invented the albumen process for coating “printing- out” paper with a mixture of salted egg whites and silver nitrate.
This resulted in a much more even and durable print.

9. Collodion
In 1849, Englishman Frederick Scott Archer introduced the collodion process, which used a glass plate coated with collodion (a mixture of guncotton dissolved in alcohol and ether) to make either a glass negative, an ambrotype (underexposed negative on glass backed with a black tarry substance called japan) or tintype (on metal). The process was called, “wet plate” because the collodion emulsion had to be exposed while it was still slightly wet.
After exposure, the plate has to be developed immediately in a silver nitrate solution and fixed in a bath of potassium cyanide.
Glass negatives were better than paper ones because they were smoother and held more detail.

12. The World’s Fair
In 1851, the World’s Fair, or Grand Exhibition, came to London. Photography was one of the biggest sensations of the Fair.
One of the most popular photographic subjects of the time were the iron and steel structures that were beginning to gain popularity with the emergence of the Industrial Revolution.

13. Cartes de Visite
Introduced in Paris in 1854 by Adolphe Eugene Desderi, the Carte de Visite became a sensation in one European country after another. The small format reduced costs, which made photography more available to the masses. Millions of people loved to collect photographs of famous people. The sensation was so strong that by 1867, celebrities like Charles Dickens started demanding payment to have their pictures taken. This was the beginning of the paparazzi.

14. War Photography
The Englishman, Roger Fenton, was one of the men who was commissioned as the first government photographers for a war.
Here he is seen with his traveling photographic studio, or van.

15. Strategy
In 1855, the Crimean War became the first war to be photographed. Since exposures were still recorded in seconds, not fractions of seconds, battle scenes were too fast and furious to capture with a camera. Most photographs are of battlefields, corpses or officers or soldiers resting in their camps.
Although many images were manipulated for artistic reasons, these images were more for strategic use by the military and government- scouting battle fields, recording losses- than for public consumption.

16. Propaganda and The American Civil War
From 1861 to 1865, the American Civil War was recorded with more intensity than the Crimean War.
For the first time, photographic images played a major part in affecting the outcome of a war by showing the average American exactly what their brothers and uncles and fathers and sons were going through. The brutality of the images made public sentiment turn towards finding a peaceful solution.
Many photographers posed their subjects to make a more pleasing composition and a more powerful poetic statement about the horror of war.

17. Documents of Destruction
Particularly after the brutal slash and burn tactics of Sherman’s March, captured on glass plates by George N. Bernard, both Northerners and Southerners were more and more prepared to sign a peace treaty.

18. Westward Expansion
Photography also played a large part in the opening of America’s western frontier. By showing the beauty of the frontier, photographers helped expand the reach of American culture and fed the American ideals of hard work, fortitude and national pride.

19. Problems Remain
In 1870, there were still some major problems with the photographic processes:
Complex processes made it necessary to have a portable studio in the field and several very skilled workers to run a studio.
Shutter speeds were still at least one second.
Big, heavy cameras made photography a very strenuous activity. Mules and crews of men were used to haul photographic equipment in the field.
Images could not be made in more than one color.

20. Simplifying the Process- Silver Bromide and Silver Gelatin
The biggest advancement toward modern photography since Talbot’s calotype came in 1871 when Dr. R.L. Maddox introduced the silver bromide/ silver gelatin process. This was a “dry” process, which meant that the paper negative could be prepared long before the image was to be captured. This process also eliminated the need for portable field darkrooms because the paper could wait to be developed hours or even days later.
This “dry” process also meant that manufacturers could produce large quantities of sensitized paper and sell it. By 1879, the process had been improved so much that a vastly larger number of people could practice photography without having to go through the process of sensitizing the glass or paper negatives themselves.

21. High Speed Exposures
Starting in 1872, Eadweard Muybridge began experimenting with ways of capturing images in fractions of seconds.
In 1878, he succeeded in capturing on collodion a horse in full gallop. This was the first time that motion phenomena previously unobservable by the human eye could be proved. These images shattered the conventional ways of depicting horses in art.
Faster exposures opened the door for a better scientific understanding of body mechanics. This was extremely helpful to doctors as well as artists.

22. George Eastman and the Kodak
In 1884, the Eastman Kodak company patented roll film. He came up with the idea of coating silver emulsion onto a new substance called cellulose- a form of a new substance called plastic. Roll film made motion pictures possible because it could be wound onto reels and passed in front of a projector.
Roll film also made it possible to fit the film into much smaller cameras that were easier to use than the big bulky wooden cameras needed for glass or metal plates.

23. Invasion of the Snapshot
In 1888, the Eastman Kodak company patented its first hand held camera. Each camera came with 100 preloaded shots. The photographer simply snapped the pictures, sent the camera to Kodak for processing and received the prints as well as a newly loaded camera.
In addition to being easier to use, the Brownie made the photographic processing even easier by eliminating it altogether for the photographer.
Photography as we know it was on its way!

24. The Last Major Problem- Color
In 1868, Louis Ducos du Hauron and Charles Cros both independently hit upon the idea of using three separate colored negatives- made by using colored filters and colored papers- to make a full spectrum color image.

25. Autochrome
Du Hauron and Cros’ processes were not commercially viable, but it lead to the development of “Autochrome” by the Lumiere brothers in the early 1900s.
Autochrome became the first commercially available color photographic process in 1903.
