  1.  1824
    1824 - Joseph Svec creates Harbor Country Botanical Prints. Each of his photographic images is an unique, one-of-a-kind original. They are created using an early photographic process called cyanotype. The cyanotype process was invented by Sir John Herschel in1824. These cyanotype images are made by coating a mixture of photosensitive chemicals onto watercolor paper. After the paper is allowed to dry found-objects are arranged on the surface and covered with glass. 

    1837 - The daguerreotype was the earliest commercial photograph available to Americans. Named for Frenchman Louis Daguerre, who perfected this photographic process in 1837, the daguerreotype was produced directly on coated metal without a negative . The daguerreotype was easily made in the mid-1800s. Photographic plates were copper faced with silver, polished with flannel and rottenstone, taken to the dark room to be sensitized (coated with thin layers of bromine and iodine). 

    1839 - It is no longer a question of zy"digital capture will become the major photographic capture process; that will come to pass in the near future. Since the photographic processwas first used in 1839, there been a constant march toward development of a more convenient picture-making method. Photography evolved from the dangerous and slow daguerreotype to the modern Polaroid® dye migration process. Negative processes could be duplicated, but the direct processes were not convenient. 

  3. 1839 - Of late years there have been devised a great variety of new photographic processes, some of which are given below, together with modern formulae for the principal solutions, &c., in general request by the photographer. The Daguerreotype process, discovered by M. Dagutrre in 1839, has been entirely super- seded by the easier, healthier, and less expen- sive collodion processes described further on. It consists in submitting n plate of silver or silvered copper to the vapour of 
    1839 - Henry Fox Talbot, an English inventor, perfected his own process, and in 1839invented the negative process. With his process, the calotype, many prints could be made from a single negative. Although the daguerreotype was more popular at the time (possibly because it was a free to use patent, unlike the calotype which was licensed), the fact that Fox Talbot's calotype was a double negative process meant that it became the precursor to most late 19th and 20th century. 

    Jan 7, 1839 - The daguerreotype was the first successful photographic process in the history of photography. On January 7, 1839 the daguerreotype was presented at the ' Académie des sciènces' in Paris. The daguerreotype is named after Louis-Jacques- Mandé Daguerre (1787-1851), who invented the process together with Nicéphore Niépce (1765-1833). The basis of the daguerreotype is a highly polished metal plate, consisting of a wafer-thin layer of silver on a copper 
    Jan 7, 1839 - The Daguerreotype was the first successful photographic process, the discovery being announced on 7 January 1839. The process consisted of. exposing copper plates to iodine, the fumes forming light-sensitive silver iodide. The plate would have to be used within an hour. exposing to light - between 10 and 20 minutes, depending upon the light available.
    Jan 9, 1839 - World Photography Day originates from the invention of the Daguerreotype, aphotographic processes developed by Louis Daguerre. On January 9, 1839, The French Academy of Sciences announced the daguerreotype process.

    Aug 19, 1839 - On August 19, 1839, at the Institut de France in Paris, the distinguished physicist, Francois Arago, announced to the world on behalf of the French Government the details of Daguerre's process which became known as the daguerreotype. Like Ambrotypes and tin types, the Daguerreotype process produced a positive image, but it is from a negative-positive process developed by an Englishman, William Fox Talbot that our modernphotographic processes stem.

    1840 - The result of this was the publication, in 1840, in the "Philosophical Transactions," of an important memoir " On the Chemical Action of the Rays of the Solar Spectrum on Preparations of Silver and other Substances, both Metallic and Non- metallic, and on some Photographic Processes," and a second memoir " On the Action of the Solar Spectrnm on Vegetable Colors, and on some New Photographic Processes."
  10.  1841
    1841 - In 1841, William Henry Talbot invented the calotype process. This was the first negative positive process that allowed the photographer to create multiple copies of the same image. This opened many new doors for how photography could be used; the most important being for advertising. Just one decade later Frederick Scott Archer invented anotherphotographic process. The collodion process only required a mere two or three seconds of light exposure.

  12.  1851
    1851 - Recently I saw a post on The New Modern about a documentary of Sally Mann's process to photograph Civil War battlefields using a Civil War era photographic processes. Introduced in 1851, the wet-plate collodion process is a method of making photographic negatives on glass plates that have been coated with light- sensitive chemicals. The plate is then coated with a silver nitrate solution, loaded in a plate holder into the camera, and then exposed while still wet and sticky.
  13.  1856
    1856 - The ferrotype, also called the tintype or melainotype, is a photographic processdeveloped in the United States in the 19th century. It was invented by Prof. Hamilton Smith of the Kenyon College, Ohio in 1856. Basically the process falls under the category “wet plate processes”, where the photographic emulsion is contained in liquid collodion. 

  14. 1880 - Figure 32, a typical group image published in 1880, pictures Ferdinand de Lessep's Commission that presided over the building of the Panama Canal, photographed on location by Alfredo Orillac, the Ilustracion Espanola y Americana's correspondent in Panama. 72 This image demonstrates how adept the magazine's artists and technicians were becoming at combining photographic processes with hand processes.

    Oct 9, 1977 - BINH DANH was born in Vietnam on October 9, 1977. Having recently received his BFA in Photography from San Jose State University, he has exhibited his work regionally and has lectured on his work nationally. Danh's work often addresses and reflects his Vietnamese heritage and interest in natural science and history . He utilizes 19 centuryphotographic processes such as daguerreotypes and tintypes in his contemporary image -making.

    May 1, 2010 - Wet Plate Collodion photographic process, a new commemorative plaque will be unveiled on his grave (Square 120 by the canal) on Saturday, May 1, 2010. The Collodion Collective and World Wet Plate Day organized and is sponsoring this event.

    Alternative Processes really interested me since it opened my eyes to fine are side of photography. A stronger connection is made between photographer and the image produced when using alternative processes to create an image as it is more hands on. 
    I also enjoy the scientific side to subject and how the chemicals react with other chemicals.
