Louis-Jacques-Mandé Daguerre was a Frenchman, who was born on Nov. 18, 1787. He was a chemist, and known for his artistry. He is well known for know inventing the daguerreotype. It was a process in which a picture only needed 20 to 30 minutes of exposure time, instead of eight hours. He was also a scenic painter for the Diorama, which he opened. He realized he could change the effects of the pictures with different lighting. Daguerre was always interested in obtaining a lasting image, and from the influence of his partner Niépce, he discovered that exposing an iodized silver plate in a camera would do just that. This would work if the plate was developed by exposure to fumes of mercury and made permanent by a solution of common salt. The image was reversed, like a mirror, so it could only be viewed at an angle and in a glass box. Overall, daguerreotypes were usually portraits. It was said that daguerreotypes were the Polaroid of its day.
