Camera technology has been around for centuries and was first introduced by Aristotle's sketches where he created the foundation for future inventors to develop off of. The first device created by an artist was in the mid-1500s called the camera obscura(dark chamber) which had a lightproof box with a pinhole on one side and a translucent screen on the other. Another advancement was called the daguerreotype camera which was made in the daguerrotype process by opticians and instrument makers. It had a sliding box design with a lens placed in the front box with a smaller box inside it which showed a laterally reversed image unless the camera was fitted with a mirror. The box camera was made by George Eastman which he called the Kodak Camera which was $22.00 with enough film for 100 shots. After it's use then send the camera back to the company to process the film. Another invention called the flashlight powder invented in Germany in 1887 by Adolf Miethe and Johannes Gaedicke using lycopodium powder was the first type of flash they used. Later on the first modern flashbulbs were invented by Paul Vierkotter using magnesium-coated wire in an evacuated glass globe which was more effective. Filtres were introduced by Frederick Wratten and manufactured and sold collodion glass plates and gelatin dry plates using the "noodling process" of silver-bromide gelatin emulsions before washing. This advanced the way pictures would be seen and added a certain effect to a picture. 35mm cameras was created by Oskar Barnack when he had the idea reducing the format of film negatives and then enlarging the photographs after they had been exposed. Edwin Herbert Land made the first polaroid photogrpahy which printed photos instantly in 1948. Fuji introduced the disposable camera in 1986. In 1984, Canon demonstrated first digital electronic still camera.
