History of photography

1826

• Frenchman Nice’phore Nie’pce produces first permanent photograph of a view from nature. Uses the photosensitivity of bitumen of Judea.

1829

• Frenchman Jacques Louis Mande Daguerre and Nicephore Niepce sign partnership agreement to work on perfecting photography.

1839

• January: Englishman William Henry Fox Talbot presents to the Royal Society of London a paper on photogenic drawing, permanent camera obscura images made with photosensitive silver salt on paper.

1839

• August: Noted French scientist Francois Arago, with Daguerre, announces the details of the first commercially practical photographic process, the daguerreotype, before a joint session of the French Academies of Science and Fine Arts. A sharp mirror- like image on a silver copper plate, the daguerreotype exploits a photosensitive latent image that is developed with mercury. The direct positive images start a craze of popular interest.

1841

• Talbot parents the calotype, a negative-positive process on paper that employs the latent image develop by gallic acid.

1839

• March: American Samuel F.B Morse, in Paris to promote his telegraph, meets with Daguerre and returns to New York to teach the process. Among his pupils is noted Photographer Matthew Brady.

1850

• English Frederick Scott Archer coats glass plates with sticky wet collodion with silver salts.

1850

• Frenchman Louis- Desire Blanquart-Evrard makes positive photograpic prints on paper coated with albumen (egg whites).

1851

• From 1851-1854, ambrotypes are introduced in Europe and U.S and used in the 1850’s. these wet collodion images are direct positive by blackening the back of the glass plate and like daguerreotypes are carried in plastic cases. Replaced with wet collodion negative and positive paper prints that dominate photography next 25years.

1854

• July 12: George Eastman is born in Waterville, New York.

1860

• February 27,1860: Matthew Brady takes a photographic portrait of Abraham Lincoln in New York.

1861

• In London, James Clark Maxwell demonstrates a projected color photographic image, using three different color filters.

1871

• Englishman Richard L. Maddox discloses the gelatin dry-plate process for photography. Commercial exploitation begins in 1878

1873

• John Wesley Hyatt trademarks the name “celluloid” in U.S and great Britain.

1877

• August: American Eadweard Muybridge develops a fast shutter that aids him in making photographs of objects in motion.

1877

• George Eastman prepares to travel to Santo Domingo to speculate on land. To document his findings he begins study of photography.

1878

• Among numerous English photographers, Charles Bennett improves gelatin dry plate photography, increasing the photosensitive of the silver salted gelatin emulsion (hence photographs take less exposure time). Eastman sees the report in the “British journal of photography.”

1880

• April: George Eastman patents “a method and apparatus for coating plates for use in photography.”

• April: George Eastman sets up a photographic dry-plate production shop in Rochester.

1881

• January: Henry Strong begins to invest in the Eastman Dry Plate company, becoming president. George Eastman is treasurer.

1881

• September 5: George Eastman resigns from his position at the Rochester Savings bank. Etienne- Jules Marey invents a repeating camera that records multiple images on the same plate.

1885

• May 5: George Eastman and William Walker receive patent for the Eastman- Walker Roll Holder, a device that advances film for cameras to which it it attached. Soon afterwards , Eastman Walker to England head to his London office.
