George Eastman

George Eastman.

In 1976, Kodak had a 90% share of photographic and camera sales in the United States. Everybody knew what was meant by saying “It’s a Kodak moment.”

But it was not always that way. It took a long road to get to the stage we were at in photography in 1976. Greek and Chinese philosophers described the optics and camera as early as fourth century and Isaac Newton described white light as being composed of many colors in the mid-1600s. It took another 100 years before silver nitrate was discovered to darken upon the exposure of light. Silver nitrate is the basic ingredient used to capture an image on celluloid or paper. The camera obscura was used to make the first photographic image in 1814, but it took eight hours to produce the picture and faded shortly after making. Louis Daguerre in 1837 made his first daguerreotype. It took only 30 minutes to make and lasted forever. He had discovered how to stop the silver nitrate reaction from going further and darkening. In 1840, Alexander Wolcott got the first patent for a camera. More developments on the film allowed the picture to be taken but it was not necessary to develop the film immediately as had to be done up to now.
