Innovation: Commercial color photography
Location: Rochester, NY
Year: 1935
Inventor: Leopold Godowsky Jr. , Leopold Mannes

In 1935, Leopold Mannes and Leopold Godowsky, both passionate musicians, revolutionized color photography by inventing Kodachrome color film. They created a simple film for color photography, which was very easy to use and of exceptional quality. This new technology created a cultural, artistic and commercial revolution as many photographers started using it for both still and motion picture photography. Kodak started selling 16mm movie films their first year, and then they introduced the 35mm and 828 format for still cameras.

To obtain a color image it depends on the division of light into three components, red, green, and blue-violet. It is necessary to convert each component image of the negative into a positive image. The images in the three layers are developed, then by a series of treatments they are transformed into positives. At the end of the process, the image consist of three superimposed dye pictures. This whole process was known as the Kodachrome process, which made photography easy to create. Unfortunately this great innovation ended its production in June 2009, being replaced by digital cameras.
