Unfortunately, Nicéphore Niépce passed away in 1833 and his partner in crime, Louis Jacques Mandé Daguerre invented his own prototype five years later in 1838. This “daguerreotype” had a very similar concept to that of Niépce’s. A silver plate would be exposed to the camera where then mercury vapors would interact with the silver iodide coating on the plate to lament the image on the plater after being exposed to light. This finding led Daguerre and many other members within this community to idealize this into the overall concept of light exposure. Daguerre’s prototype’s exposure to light took less than 30 minutes for the image to develop. After the final image is set he would touch it up with salt water.
