It was not until the early 19th century, however, that photography actually came into being.Johann Heinrich Schulze proved that the darkening of silver salts, a phenomenon known since the 16th century and possibly earlier, was caused by light and not heat.He demonstrated the fact by using sunlight to record words on the salts, but he made no attempt to preserve the images permanently.Calling the process heliography (“sun drawing”), Niépce succeeded from 1822 onward in copying oiled engravings onto lithographic stone, glass, and zinc and from 1826 onto In 1826/27, using a camera obscura fitted with a pewter plate, Niépce produced the first successful photograph from nature, a view of the courtyard of his country estate, Gras, from an upper window of the house.The exposure time was about eight hours, during which the sun moved from east to west so that it appears to shine on both sides of the building.heliographic process, yet all his other attempts, whether made by using a camera or by means of engravings, were underexposed and too weak to be etched.Nicéphore Niépce, an amateur inventor living near Chalon-sur-Saône, a city 189 miles (304 km) southeast of Paris, was interested in lithography, a process in which drawings are copied or drawn by hand onto lithographic stone and then printed in ink.Not artistically trained, Niépce devised a method by which light could draw the pictures he needed.The essential elements of the image are usually established immediately at the time of exposure.This characteristic is unique to photography and sets it apart from other ways of picture making.In truth, however, photography is not the automatic process that is implied by the use of a camera.Although the camera usually limits the photographer to depicting existing objects rather than imaginary or interpretive views, the skilled photographer can introduce creativity into the mechanical reproduction process.
