How did George Eastman's roll camera work?

Answer 1

George Eastman, the Creator of Memories

George Eastman's invention of the roll film, dry plate, and the hand-held camera impacted the world immensely, and helps the world by making Photography more accessible to people, and more economical. He had handicapped siblings. When George was 8 his father died, this affected him because he had to get a job soon and get money for his family. He began his business career as a 14 year old office boy in an insurance company and followed that with work as a clerk in a local bank. (His mother died when he was 53 years old.)

In 1879 he got permission by the government to sell his invention, which was a machine that coats dry plates with chemicals. A dry plate is a glass photographic plate coated with a sensitive emulsion of silver bromide and silver iodide in Gelatin. In 1881 Eastman Dry Plate Company started. The chemicals on the dry plates reacted to sunlight, and that is how pictures are made.

George Eastman wanted to simplify photography and make it available to everyone, not just trained photographers. In 1883, Eastman announced the invention of photographic film in rolls. This company also manufactured the flexible transparent film, devised by Eastman in 1889, which proved vital to the subsequent development of the motion picture industry. The roll-film Kodak became an international sensation almost overnight. The film was a lot lighter than the dry plates were.

In 1888, George developed a simple hand-held camera that used his rolled film and could be marked to the general public. Kodak, the company, was born in 1888 when the first Kodak camera entered the market. Pre-loaded with enough film for 100 exposures, the Kodak camera could easily be carried and hand-held during its use. After the film was used up, the whole camera was returned to the customer. On September 4, 1888, George registered the "Kodak" trademark for his new camera company with the US government. He also came up with the company's slogan of " You press the button, we do the rest."

The invention of the dry plate, roll film, and hand-held camera impacted the world, because photography was the perfect solution to art in the time of the enlightenment; scientific, reason able without unnecessary flourishes. However the invention of photography changed the value of art - it could no longer be stated that art made after the invention of photography was only valuable as a snapshot of that time period; for that was the job of the camera. Photography is now more accessible to more people.On March 14, 1932, Eastman invited some friends to witness a change of his will. After some joking and warm conversation, he asked them to leave so that he could write a note. Moments later, he shot himself once in the heart with an automatic pistol. The note found by the household staff read simply: "To my friends, my work is done--, why wait?" When his casket was carried out of the Eastman House, the accompanying music was *Marche Romaine*.
