In 1829, Louis Daguerre, a French artist and chemist, began working with Joseph Niepce to develop a better photographic process. In general, won the physautotype, working until Niepce's death in 1833. Daguerre continued his work alone and in 1839, Louis Daguerre announced his perfection of the daguerreotype camera. It uses a copper plate sensitized slide to record and sat on a wooden tripod. The latter model reduces the exposure time of approximately 30 minutes instead of hours and, fortunately, there was no confusion of the image as a model. The daguerreotype was the first commercially viable process for making portraits and almost gave birth to the "professional photographer".
