||Frenchman Nicéphore Niépce produces first permanent photograph of a view from nature. Uses the photosensitivity of bitumen of Judea.
||Frenchmen Jacques Louis Mande Daguerre and Nicephore Niepce sign partnership agreement to work on perfecting photography.
||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 salts on paper.
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.
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 silvered copper plate, the daguerreotype exploits a photosensitive latent image that is developed with mercury. The direct positive images start a craze of popular interest.
||Talbot patents the calotype, a negative-positive process on paper that employs the latent image developed by gallic acid.
||Englishman Frederick Scott Archer coats glass plates with sticky wet collodion with silver salts.
Frenchman Louis-Desire Blanquart-Evrard makes positive photographic prints on paper coated with albumen (egg whites).
||From 1851-1854, ambrotypes are introduced in Europe and U.S. and are used in mid1850s. These wet collodion images are made direct positives by blackening the back of the glass plate and like daguerreotypes are carried in plastic cases. Replaced with wet collodion negatives and positive paper prints that dominate photography next 25 years.
