Greetings from Tunisia… The year? 1899. These vivid postcards were produced using the photocrom technique, a photographic process invented by a Swiss printer back in the 1880s. A bazaar's thoroughfare is captured with light streaming in from cracks in the roof; a snake charmer entertains locals in backstreets; women sit cross-legged on the footpath selling grains and spices; and men gather, some donning turbans and others, top hats. It’s a striking juxtaposition of French and North African cultures, with tiny details of day-to-day life captured through a rare social realist lens.
Photocrom is considered to be half-photography and half-printing. It was a time-consuming process that involved the coating of a lithographic limestone tablet with a light–sensitive solution. The tablet was exposed to sunlight under a photo negative for many hours and then hardened to match the tones of the negative. This produced a lithographic image on the tablet. The process was then repeated to achieve the colours and image the photographer desired.
It all seems like a breathtaking amount of work… which may explain why the last photocrom printer closed in 1970. They sure don’t make postcards like this any more.
