Historic Photographs - Photographic Processes. The decades following photography's experimental beginnings in the 1820s and the public availability of a practical photographic process from 1839 were characterised by the introduction of a bewildering proliferation of photographic processes. Daguerre's silvered metal plate, which created a unique photographic image, was swiftly challenged by the negative-positive processes on paper, developed and championed by William Henry Fox Talbot and others. In the 1850s paper gave way to glass as the preferred negative support and the salted paper print of the 1840s was superseded by albumen and other papers.
This evolution was driven by a complex interrelationship of artistic, technical and commercial needs. If individual photographers defended the superior expressive potential of particular processes and techniques, scientific attention, aware of the fugitive silver image's proneness to fading, was being directed towards printing processes using more permanent compounds, such as carbon. The story of the First Photograph Ever Taken - AGONISTICA.
The First Photograph Ever Taken “View from the Window at Le Gras” [Circa, 1826] The First Photograph, or more specifically, the world’s first permanent photograph from nature, was taken by Joseph Nicéphore Niépce in 1826 or 1827. The image depicts the view from an upstairs window at Niépce’s estate, Le Gras, in the Burgundy region of France. Earliest Known Photograph  Earliest known, surviving heliographic engraving in existence, made by Nicéphore Niépce in 1825 by the heliography process. His illustration is of an etching printed from a metal plate that was etched following alteration of the ground by sunlight; the image is of a 17th Century Flemish engraving showing a man leading a horse. (via) The First Photograph of a Human ”Boulevard Du Temple” [Paris, 1838] Boulevard du Temple, taken by Louis Daguerre in late 1838, was the first-ever photograph of a person.
The First Light Picture and Human Potrait Ever Taken [Oct,Nov 1839] Roger Fenton’s Photographic Van  About the Camera Obscura. The camera obscura, literally "dark room", is a device that makes use of an optical phenomenon in which light rays reverse themselves when they pass through a small aperture. At its most basic, light rays pass through a tiny hole and recreate themselves upside down on a screen that is placed parallel to the hole. As camera obscura technology improved in the 16th century, camera obscuras became portable boxes which incorporated lenses and mirrors, so that the image was reflected onto a viewing surface which was visible outside the box. Portable camera obscuras were used as aids for draughtsmen and painters. The camera obscura became the prototype for the modern day camera, invented in the first half of the 19th century, which uses light sensitive papers and films in order to preserve the image that is projected.
As lens technology improved, the size of the surface on which the image was projected was able to be increased. Charles Schwartz Charles Schwartz' Email. History of Photography and the Camera. Updated October 05, 2015. continue reading below our video Niepce placed an engraving onto a metal plate coated in bitumen, and then exposed it to light. The shadowy areas of the engraving blocked light, but the whiter areas permitted light to react with the chemicals on the plate. When Niepce placed the metal plate in a solvent, gradually an image, until then invisible, appeared.
In 1839 after several years of experimentation and Niepce's death, Daguerre developed a more convenient and effective method of photography, naming it after himself - the daguerreotype. Daguerre's process 'fixed' the images onto a sheet of silver-plated copper. In 1839, Daguerre and Niepce's son sold the rights for the daguerreotype to the French government and published a booklet describing the process. Talbot sensitized paper to light with a silver salt solution. Photography advanced considerably when sensitized materials could be coated on plate glass. History of Photopraphy. The word photography comes from two ancient Greek words: photo, for "light," and graph, for "drawing. " "Drawing with light" is a way of describing photography. When a photograph is made, light or some other form of radiant energy, such as X rays, is used to record a picture of an object or scene on a light-sensitive surface.
Early photographs were called sun pictures, because sunlight itself was used to create the image. Mankind has been a maker of images at least since the cave paintings of some 20,000 years ago. With the invention of photography, a realistic image that would have taken a skilled artist hours or even days to draw could be recorded in exact detail within a fraction of a second. Today, photography has become a powerful means of communication and a mode of visual expression that touches human life in many ways. Photographs are used extensively by newspapers, magazines, books, and television to convey information and advertise products and services. Photography as Art C.
