Johann Heinrich Schulze of Magdeburg created photographic images of words by placing paper masks on the surface of a bottle containing chalk, aqua regia, and silver. However, despite the centuries-long use of the camera obscura among painters for the accurate representation of landscapes, photography would not be invented until much later. Joseph Nicephore Niepce used silver chloride for his original images, and Louis Daguerre used silver plates sensitized with iodine vapor.
