The History of CameraAs early as 1727,a German physicist discovered that light darkens silver salt,a chemical compound.Using as a camera,a big box with a small hole to let the light in,he made temporary images on the salt.Sil-ver salt is still the base of film today.Then a French scientist made the first permanent picture by using a special piece of metal sensitized with silver salt.A photograph he made in 1826 still exists.The painter Dagire improved on the process by placing common salt,the kind we eat,on the metal.This was in 1839,the official date of the beginning of photo-graphy.But the problem was the printing of the photographs.And it wasn't until other scientists developed the kind of paper we now use that good printings was possible and photography became truly modern.In the 1860's,Matthew Bready was able to take his famous pictures of the American Civil War.In the 20th century George Eastman of the United States simplified film developing and Dr Edward Land invented the so-called instant camera with self-developing film.If we say that photography came into existence in 1893,it follows that it has taken more than 100 years for the camera to reach its present condition of technical refinement.
