View of Lake Lugano and the city of Lugano, Switzerland, from the foot of Monte San Salvatore in 1909. Lying on the border of Italy, Lugano is located in the Italian-speaking canton of Ticino. This image was taken before the advent of color film. It is composed of three monochrome pictures shot through different colored filters and could only be viewed at the time via projection. It was only with digital image processing that the images could be satisfactorily combined into one. Photo credit: Sergei Mikhailovich Prokudin-Gorskii |
