     Before the Autochrome process was perfected in France, this photograph of a landscape in Southern France was taken. No, it is not hand-tinted. This is a color-photograph. (Note: It was published in a Time/Life Book entitled "Color" in 1972, "courtesey of George Eastman House, Paulus Lesser.") You are looking at the birth of color photography seven years after the American Civil War. 130 years ago this view of Angouleme, France, was created by a "subtractive" method. This is the basis for all color photography, even today. It was taken by Louis Ducos du Hauron who proposed the method in 1869. It was not until the 1930's that this method was perfected for commercial use.
