The Daguerrotype is a photo taken by an early photo taking process that included an iodine-sensitized silver plate and mercury vapor. It was invented b Daguerrotype was Louis Daguerre in 1839. It was the first photo in history and showed up upside-down and backwards. To even make a daguerrotype in England required you to pay a fee. To get the full effect, you should definitely see it in person. Then there were Cyanotypes, that are most commonly called photographic blueprints. The inventor of the Cyanotypes was Sir John Hershel who used Potassium Ferricyanide and ferric ammonium. To help the photo develop, you would fully submerge it in a tub of water and it would develop.
