Photography
For the image obtained, see Photograph. Lens and mounting of a large-format camera Photography is the science, art and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.[1] Photography is employed in many fields of science, manufacturing (e.g. photolithography) and business, as well as its more direct uses for art, recreational purposes, and mass communication. Etymology[edit] The word "photography" was created from the Greek roots φωτός (phōtos), genitive of φῶς (phōs), "light"[2] and γραφή (graphé) "representation by means of lines" or "drawing",[3] together meaning "drawing with light". Several people may have coined the same new term from these roots independently. History[edit] Precursor technologies[edit] A camera obscura used for drawing images Photography is the result of combining several technical discoveries.

Their images are proof that photography matters—now more than ever. By Robert Draper Thirty-four years before the birth of this magazine, the Danish philosopher Søren Kierkegaard sourly prophesied a banal fate for the newly popularized art of photography. The National Geographic Society did not set out to test Kierkegaard’s thesis, at least not right away. By wresting a precious particle of the world from time and space and holding it absolutely still, a great photograph can explode the totality of our world, such that we never see it quite the same again. Today photography has become a global cacophony of freeze-frames. When I tell people that I work for this magazine, I see their eyes grow wide, and I know what will happen when I add, as I must: “Sorry, I’m just one of the writers.” Apparently they wouldn’t have it any other way. Robert Draper is a contributing writer.

Biology and Photography The f-number of the human eye varies from about f/8.3 in brightly lit conditions, to about f/2.1 in dark conditions.Source: Wikipedia To work out the focal length of the human eye, you would need to take into account the light-reflecting properties on liquids in the eye.Source: Wikipedia F-numbers are actually written as they are due to human biology, or more specifically, due to the logarithmic nature of human perception. Human behaviour and photography Today we snap as many photos every two minutes as humanity as a whole did in the 1800s.Via: Fstoppers Which is your best side? Photography Record Breakers

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.

Early Photography: Niépce, Talbot and Muybridge | Early photography By modern standards, nineteenth-century photography can appear rather primitive. While the stark black and white landscapes and unsmiling people have their own austere beauty, these images also challenge our notions of what defines a work of art. Photography is a controversial fine art medium, simply because it is difficult to classify—is it an art or a science? Nineteenth century photographers struggled with this distinction, trying to reconcile aesthetics with improvements in technology. The Birth of Photography Joseph Nicéphore Niépce, View from the Window at Gras (1826)Although the principle of the camera was known in antiquity, the actual chemistry needed to register an image was not available until the nineteenth century. Artists from the Renaissance onwards used a camera obscura (Latin for dark chamber), or a small hole in the wall of a darkened box that would pass light through the hole and project an upside down image of whatever was outside the box.
