William Henry Fox Talbot began his pathway in photography in 1834. It wasn’t until 1839 when Jacques Mandé Daguerre created his daguerrotype that he began to take more of an interest in the subject. In 1841, Talbot contacted the patent office to have his prototype patented. He named it the calotype. The calotype was one of the first negative-process machines that permitted the copying of the same image multiple times. This was possible by having a translucid negative wax on the silver chloride paper. A second sheet of paper was then covered in the same silver chloride solution and when exposed to the translucid negative the final result was then developed.
