From the Paper:

"There were many attempts until the XIX century to capture drawings or images using the reaction to light, but the resulting work always deteriorated. In 1816 Joseph-Nicephore Niepce succeeded to capture the first negative images, using paper treated with silver chloride but failed to fixate the image. He managed to achieve positive images using a pewter plate covered with a petroleum derivative called bitumen of Judea . Although ti was successful there were still many problems to cover. He received the reversed image, and the exposure took hours to fixate the picture, which caused the sun to move and alter the position of the light. Louis Jacques Mande Daguerre, interested in Niepce's work conducted his own researches. In 1835 he published his first results, called daguerreotype. This was a sheet of silver-coated copper, treated with iodine vapor. He achieved to reduce the exposure time to 30 minutes, achieving a barely visible image that he later revealed with mercury vapor and fixated with salty hot water. "
