Sepia tone images simply add a dash of colour to a black and white image.This photographic technique has its roots in the 1880’s. At that time photographic prints were exposed to sepia in order to replace the metallic silver in the photo emulsion. By doing the replacement the photo developer could change the colour, and increase the tonal range of the photo. It was also believed the sepia toning process increased the life of the print, which explains why so many sepia photographs still exist. So where did this sepia come from? Sepia is nothing more than the ink extracted from a cuttlefish.
