1521: The first publication on the camera obscura is that of Cesare Cesariano, a pupil of Leonardo during the Renaissance.
1550: Girolamo Cardamo adds a “crystal disc” to the camera obscured
1600: The chamber that until then was a room as such transformed into a portable wooden instrument. Johann Zahn transformed that box into a tool similar to that used in the principles of photography.
1630: Cristopher Sheiner invents a parallelogram system to expand or reduce the drawings
1685: According to treaties published by Zahn and the camera was ready for photography but had to spend 130 more years so that it could give the first concrete results; even the chemists were not prepared.
1727: John Schulze while experimenting with phosphorus, realised that the compound closest to his windows turned purple. I conclude that the silver salts darken if they subjected to intense light.
1777: In the style of the paintings of successful artists of this century like Canaletto it seems evident the use of this powerful tool, the camera obscura.
1801: A few years before his death the English Thomas Wedgwood made the latest discoveries in the procedures to capture images, but until his end in 1805 he failed to make them permanent.
1816: Nicephore Niépce achieves the first images on paper. In this year he advocates the use of the diaphragm. He had managed to fix the pictures of the camera obscura on paper treated with silver chloride by nitric acid.
1823: based on the techniques of lithography, he had the idea of applying the projections of the camera obscura to replace the absence of the artist.
1826: the first photograph called `Point of view from the Gras window ‘appears. The exposure time was 8 hours, and Judea bitumen used as a photosensitive compound.
1829: Daguerre and Niépce formed a society in which the latter was recognized as the inventor. Once Niépce is dead, Daguerre passes the invention almost completely.
1833: William Henry Fox Talbot pursued the same idea of Wedgwood, Nièpce I Daguerre. Talbot used the calotype, which obtained a negative. Successively, a positive is achieved by placing a sensitive paper on top of the negative and exposing it to light.
1837: Daguerre, Nièpce’s friend, creates the daguerreotype, fixing the images with a standard salt solution. They were positive images, but they could not be reproduced, they were fragile and delicate to see.
1838-1839: launch of the Daguerreotype. Daguerre becomes recognized and awarded eminence. Immediately begins to make a series of photographic material by demonstrating in public; one of them was reflected in a book of twelve pages of great rigour, published and discovered the secret that it contained.
1840: William Fox Talbot invents calotype. Now you can get copies of the original photograph.
1842: the photographer Carl F. Stelzner takes with daguerreotype the one that will be the first photograph of an event, a neighbourhood of his city, desolated by a fire.
1851: Sir Frederick Scott Archer, sculptor and photographer, proposed in the English magazine The Chemist, the collodion method. The collodion or cotton-powder is an explosive whose base is the nitric cellulose. This invention represented a decisive step for the photography when approaching the instantaneous image with an exhibition 15 times inferior to the one of the daguerreotype.
1854: André Adolph Disdèri, used multiple objective cameras, which allowed to make eight negatives in the same glass plate. In this way, the portrait became accessible to all layers of society.
1858: the first aerial photograph was taken.
1861: modern photography appears in the wake of a discovery made by Sir James Clerk Maxwell. He showed that any colour could be achieved by mixing lights; these were red, green and blue.
1873: Dr Maddox is considered the inventor of the gelatin emulsion, improved and brought to the market by John Burgess. Using dry, images could be taken with exposures of 1/25 of a second, enough time to do without the tripods. This made the cameras smaller.
1878: Muybridge made the series of galloping photographs of a mare with 24 cameras placed in a row, whose shutters were driven by cables that broke the mare as it passed. The result showed that the four hooves of a galloping horse take off from the ground at the same time.
1882: the manufacture of plates with orthochromatic material begins.
1884: begins the manufacture of objectives.
1888: George Eastman invented the famous Kodak camera. It had all the qualities for mass production and popular appeal: it was light, compact and the photographer did not have to reveal the photos. For the first time, a camera could be loaded with roll film and with a capacity of 100 exposures.
1902: the Photo-secession movement was founded, inspired by the secessionist movement of painters in Munich. This group brings together notable photographers, all of them led by the American Alfred Stieglitz. Its purpose was to get rid of the pictorialist tendency and impose the idea of a real and free photo.
1904: a first photograph that the Lumière brothers sent when they patented the auto chroma plate. This caused the commercialisation of colour photography.
1906: the panchromatic plate was introduced, sensitive to all the colours of the spectrum.
1907: the first autochrome plates of Lumière appear.
1913.- the first 35 mm film manufactured.
1914: many photographers looked for the simplification of the procedure with the dry plate and then the reel, achieving the reduction of the size and weight and the snapshot.
1935: The first modern colour photographic film, Kodachrome, was first used in 1935
1937: the development of the image on paper began with small ideas. We must highlight two characters: Bayard and Talbot.
1947: The Magnum Agency founded: a cooperative of photographers concerned about the photo manipulation service of photographic information in the media.
1950: New industrial processes allow to increase enormously the speed and sensitivity to light of colour and black and white films.
1960: The first VTR “Video Tape Recorder” that in 1951, were already able to capture television images, convert them into an electrical signal and store them in magnetic media.
1963: the last advance was with the Land Polaroid camera, which automatically produced colour copies.
1969: Willard Boyle and George Smith designed the basic structure of the first CCD Device Charged Coupled device CCD raised as a system for the storage of information.
1975: The first digital camera was developed by Kodak, who commissioned Steve Season to build one on December 12, 1975.
1981: first practical appearance with the invention of the colour camera made by Frederic Ives.
1988: The first real digital camera that recorded images in a computer file was probably Fui’s DS-1P model.
1991: The first digital camera available on the market was the Dycam Model 1, which was sold under the name of Logitech camera man.
1994: first integral camera of video and photography of 35 mm.
1995: The first camera aimed at consumers with a liquid crystal display on the back was the Casio QV-10 in 1995.
1996: The first camera to use Compact Flash memory cards was the Kodak DC-25 in 1996.
1997: In 1997 the first cameras for consumers of a megapixel were offered.
1999: In 1999 with the introduction of the Nikon D1, a 2.74-megapixel camera, this was one of the first digital SLRs.
2003: In 2003 the Digital Rebel of Canon, also known as the 300D was presented.
2008: In 2008, a LEICA medium-format camera with a resolution of 37 Megapixels was presented at the German Fair.
