According to the book "A World History of Photography" written by Naomi Rosenblum, the idea of photography ranges all the way back to the year 1839. She writes that "London and Paris separately announced the idea at about the same time". The first idea came from a man named Louis Jacques Mande Daguerre. His idea was called the "daguerreotype" which contained a "laterally reversed monochrome picture on a metal plate". It was said that the daguerreotype was "unique", and "unduplicatable".

His idea was very different then Daguerre's, a "monochromatic, tonally and laterally reversed—a negative image" was placed on a piece of paper instead of a sheet of metal. When the negative picture was placed in sunlight the image was transferred in reverse, causing it to look like a normal image. Rosenblum goes on to write that "Daguerre's picture on metal was far more popular during that time then Jacques's negative-positive process". But on the other it was Jacques's "negative-positive process that set the platform for developments in photography". ("A World History of Photography"
