• 1851
  • In 1851 Gustave LeGray demonstrated better results by waxing the paper before it was sensitized and processed. (sharlot.org)
  • photographers
  • Some photographers preferred the diluted albumen because it was easier to tone, though many chose matte papers for aesthetic reasons. (conservation-us.org)
  • The latter made the dry form unsuitable for the usual portraiture work of most professional photographers of the 19th century. (wikipedia.org)
  • Pioneers such as Mads Alstrup and Georg Emil Hansen paved the way for a rapidly growing profession during the last half of the 19th century while both artistic and press photographers have made internationally recognized contributions. (wikipedia.org)
  • photography
  • Later, hand-colouring was used with successive photographic innovations, from albumen and gelatin silver prints to lantern slides and transparency photography. (wikipedia.org)
  • photography was to encounter many such dead ends in the next century. (sharlot.org)
  • Due to the overwhelming response and unprecidented demand for true 19th century authentic wet-plate collodion photography, we are offering our totally unique portrait weekends again, but with thrice as many as ever before. (johncoffer.com)
  • He is interested only in what they are made of: the papers, chemicals and metals that constituted the richly varied physical world of photography for about 170 years, until the rise of digital cameras and printing a decade ago began to render it obsolete. (blogspot.com)
  • In 1856, seeing the tremendous potential for reproducible and enlarged prints and illustrated newspapers, Brady hired photographer and businessman, Alexander Gardner, who instructed him in the new art of wet-plate collodion photography. (wikipedia.org)
  • On the contrary, photography began with the camera obscura as early as the 10th century AD, and some evidence seems to indicate that Aristotle was familiar with this technique as early as the 4th century BC. (fiberq.com)
  • Her artistic goals for photography, informed by the outward appearance and spiritual content of fifteenth-century Italian painting, were wholly original in her medium. (metmuseum.org)
  • Archer
  • Archer detailed a process where potassium iodide was combined with a solution of diluted collodion (diluted with alcohol and ether), applied to a glass plate, which was then immersed in a silver nitrate bath resulting in a light-sensitive layer of silver iodide. (studioq.com)
  • binder
  • Each of these materials has a characteristic effect on the printing process, and many different printing papers may also be created by combining these various binder substances. (conservation-us.org)
  • Even if only one kind of binder is used, a whole range of effects may be accomplished by simply varying the dilution, i.e. the amount, of binder that is applied to the raw paper. (conservation-us.org)
  • Even a 2% solution of albumen causes a significant improvement in depth and contrast over a paper that is simply salted and has no organic binder at all. (conservation-us.org)
  • silver
  • The paper is then dipped in a solution of silver nitrate and water which renders the surface sensitive to UV light. (wikipedia.org)
  • These materials are of landmark historical importance and also are fundamental to any modern practice with handmade silver printing-out papers. (conservation-us.org)
  • The main differences lie in the materials and techniques of coating the raw paper with organic binders to carry the silver image. (conservation-us.org)
  • Since silver nitrate is water soluble and was observed to darken when exposed to light either in solution or dried, it would seem to be the simplest of experiments to dip paper into a solution and make shadow pictures in the sun. (sharlot.org)
  • The sizing materials used in some papers prevented good penetration and wetting, as did silver salts and processing residues. (sharlot.org)
  • He first developed the Talbotype, which used silver chloride to sensitize paper. (wikipedia.org)
  • exposure
  • Though direct sunlight was used long ago, a UV exposure unit is often used contemporarily because it is more predictable, as the paper is most sensitive to ultraviolet light. (wikipedia.org)
  • Collodion is normally used in its wet form, but can also be used in humid ("preserved") or dry form, at the cost of greatly increased exposure time. (wikipedia.org)
  • Interesting sidelights on the waxed paper process as practiced by Roger Fenton are given by Hannavy , particularly regarding pre-exposure and post-exposure waxing. (sharlot.org)
  • While exposure times shrank as photographic technology developed, to get a clear picture of a child during the 19th century the child had to be persuaded to stay still, which could be difficult to achieve. (wikipedia.org)
  • He originally exposed these plates to some light through an oiled etching on a piece of paper, and washed the plates with a solvent after exposure to remove the hardened parts of the image. (fiberq.com)
  • cabinet
  • Both were most often albumen prints, the primary difference being the cabinet card was larger and usually included extensive logos and information on the reverse side of the card to advertise the photographer's services. (wikipedia.org)
  • image
  • The paper with negative is then exposed to light until the image achieves the desired level of darkness, which is typically a little lighter than the end product. (wikipedia.org)
  • The collodion process produced a negative image on a transparent support (glass). (wikipedia.org)
  • 1816: Heliography The first person who succeeded in producing a paper negative of the camera image was Joseph Nicephore Niepce. (wikipedia.org)
  • In the middle of the 16th century, lenses were added to the hole of the camera obscura to produce a brighter, sharper image. (fiberq.com)
  • Over time, the camera obscura became more compact, and the image was projected onto thin paper on glass so it could be traced. (fiberq.com)
  • In 1816, Joseph Niépce and his Brother Clyde successfully produced a paper negative from the image. (fiberq.com)
  • When they sandwiched this negative with another piece of sensitized paper, a positive image would appear. (fiberq.com)

  • The Nineteenth Century gave us many things, but above all it was a hotbed of facial hair experimentation and this is but a poor sampling of those many lost forms. (blogspot.com)
  • chemicals
  • Some of that information has long been lost in the weeds of history, left there by innovators who experimented with exotic chemicals and papers and left little record of what they were up to. (blogspot.com)
  • images
  • The process could produce many positive images, but they were not as sharp because they were printed on fibrous paper rather than glass. (wikipedia.org)
