These stunning colorized photochroms show the mountains, fjords, glaciers, cities, and towns of late 19th century Norway. From the fish market in Bergen to Aalesund, these pictures show Norway moving towards a peaceful separation from Sweden. These photos were colorized using the photochrom process. This process was invented in the 1880s by a Swiss printer. A series of dyed limestone tablets were used to create a colorized black and white negative image. This technique was widely used to produce some of the earliest colorized pictures.
