An early autochrome picture showing an elderly couple in the fashions of the day, taking tea in their garden. The autochrome was introduced in 1904 by the Lumiere Company in France and was the first commercially available colour proces. It was available only in the form of slow plates, with grains of dyed starch acting as a colour filter for the light as it entered the camera. The resulting transparency produced a grainy effect reminiscent of French pointillist paintings.
