In 1824, Claude and Joseph Nicephore Niepce developed "heliography" which is a process using lithographic stones placed in a camera and exposed for eight hours to sunlight. Five years after heliography, Joseph Nicephore Niepce and Louis Daguerre joined forces to discover ways to improve and preserve these images. This process later became known as the "daguerreotype" and is achieved by coating a copper plate with silver iodide and exposing it to bright light for thirty minutes ("Photography"). Clearly, this system reduced exposure time immensely and allowed it to be preserved for much longer as well. In 1847, George Eastman created a method using spools of paper coated in emulsions of silver salts and gelatin ("Eastman, George"). Soon enough, people all over the world could own a camera no matter their age or skill. Eastman advertised his Kodak camera with the phrase, "You press the button-we do the rest!" and the camera gained increasing popularity.
