Niepce a French lithographer, took the first picture to be printed. He did so by using one of the oldest technique, Bitumen of Judea. Later in his career he collaborated with Louis Daguerre to find a process that would print photographs using silver compounds. They based on previous research by Johann Heinrich Schultz.
In 1839, by accident one day Daguerre found a solution by using silver on a copper plate. This process came to be know as daguerreotype.
An American photographer named Robert Cornelius, took the first self portrait using the daguerreotype technique. In the 1840's he was on of the earliest person to own a photographic studio.
In 1840 William Fox Talbot created the process calotype or the talbotype process. This process differed from daguerreotype because it uses silver chloride to make a negative picture.
