History of photography


photography is a word derived from the greek words photos (light) and graphein (to draw). the first photograph was taken in 1827, Joseph Nicephore Niepce developed the first photo with the camera obscura. Before joseph discovered this, people used the camera obscura for viewing or drawing purposes not for making photographs. By letting the light draw the picture also know as sun prints were the prototypes for the modern photograph. In 1856 tintypes were invented by Hamilton smith, the way it worked A thin sheet of iron was used to provide a base for light-sensitive material, yielding a positive image. By 1879 handheld cameras were invented also known as the dry plate, a glass negative plate with a dried gelatin emulsion. dry plates could be stored for a longer period of time. which meant photographers no longer needed dark rooms to develop there photos. in 1889 George Eastman  invented film with a base that was flexible, unbreakable and could be rolled. By the 1940's color photos and video's were invented, the process was dye-coupled colors in which a chemical process connects the three dye layers together to create an apparent color image. Traditionally, linen rag papers were used as a base for making photographic prints, the box camera could be purchased for $22 with film for 100 shots after the film was used up the camera was sent back to the company so the pictures could be printed. photography played a major roll in ww1 with photographs came the propaganda that promoted the war and convinced people to serve for there country. with this ww1 had a better enlistment rate due to the evolution of photography. The first modern photoflash bulb or flashbulb was invented by Austrian Paul Vierkotter. Vierkotter used magnesium-coated wire in an evacuated glass globe. Magnesium-coated wire was soonormat of film negatives and then enlarging the photographs after they had been exposed.
As development manager at Leica, he was able to put replaced by aluminum foil in oxygen. in 1905, Oskar Barnack had the idea of reducing the f his theory into practice. He took an instrument for taking exposure samples for cinema film and turned it into the world's first 35 mm camera: the "Ur-Leica".
