George Eastman Part 2

At first George Eastman’s idea was to use a lighter and more flexible support than glass, and he coated the photographic emulsion on paper and then loaded the paper in a roll holder. The view holder was used in view cameras in place of the holders for glass plates. His work was successful with some minor changes like changing the paper, which wasn’t working out due to reproducing grain from the paper onto the image. He then came up with the idea to coat the paper with a gelatin followed by a layer of insoluble light-sensitive gelatin. After the exposure and development the gel bearing the image was then stripped from the paper, transferred to a new sheet of clear gel, and then varnished with collodion (which was a cellulose solution that forms a tough yet flexible film). The transparent roll film and roll holder were finally perfected. Eastman’s goal in all this was to make the camera more convenient for the average Joe so that photography would become more popular. He realized to spread the word he would need to take a big step in advertising. His first major slogan that he bought was, “’you press the button, we do the rest.’” The same year that he trademarked this slogan was also the year that he introduced the first Kodak camera in 1888. The word started to get out about Kodak and was advertised greatly in London which was a really big step for the company. It was said that the name ‘Kodak’ was just invented out of thin air from George Eastman’s thoughts, but today it is known around the world.
