Color Film. The duo, Godowsky and Mannes, affectionately known by colleagues and friends as “God and Man” were professional musicians who enjoyed photography as a hobby. In 1916 they started experimenting with color images by taking multiple black-and-white exposures through filters of various colors. They eventually invented a practical, high-quality color film released as Kodachrome film in 1936.
