Joseph Nisefofor Nieps biography

The exposition in the chamber of the plate, covered with a layer of bitumen, or “Syrian asphalt”, lasted more than 8 hours. The author of the picture is Joseph Nisefore Nieps. Heliography technology was developed by Nieps at the turn of the X. Actually, parents-Burgundy aristocrats Father was an adviser to King Louis XV! However, in the year, the young man preferred an officer’s church career and entered the revolutionary army.

He took an active part in hostilities in Sardinia and Italy, however, health problems after Tif moved forced him to resign. The regimental commander General Kerwegen, saying goodbye to Nieps, said: "I am losing the brightest head of my headquarters in your face." In the year, he settled in Nice as a civil servant and married.

However, only 6 years. Then Nieps returned to his father and began research with his older brother Claude. Their first invention was the pyreolofor - the internal combustion engine, which was quite suitable in order to move the boat in the hay. Likopodia was originally used as a fuel for the engine - a powder from a spore of various species of plants of the plain family, then a mixture of coal and resin, as well as asphalt and oil.

It was precisely these materials that were used by Joseph Nieps in his first heliographic experiments. Joseph Nisefort Nieps in the year Claude went to Paris, hoping to find great opportunities there to realize his engine, and then to London, where he remained forever. Left alone, Joseph took up the creation of a “six inches camera on each side and with a sliding pipe and a lens”.

The date is known when he started working on the camera: April 12, a month after Claude's departure. To obtain a photographic image, Nieps was originally used silver salt, which blackens in contact with daylight. He was able to get a negative, but when the silver salt is released from the chamber, the picture was blackened. In the future, the inventor experimented with copper or limestone plates covered with a thin layer of bitumen.

For the first time, Joseph Nieps received a fixed image for about a year: it was called a “set table”, but the image was not preserved. A picture of the year is stored in the Harry Ransom Research Center in Austin Texas, enclosed in a special case, which is filled with an oxygen -sized gas mixture slowing aging. The brothers spent all their money received by inheritance to various kinds of inventions, but not one made it rich.

This photography technology based on the photosensitivity of iodide of silver was more efficient and used for two decades, replaced in the second half of the 19th century cheaper and convenient processes. Dagraurotype "Workshop of the Artist", created in the year and presented by the physicist Francois Arago at a meeting of the Paris Academy of Sciences during the announcement of the invention to share the link:.
