In 1950, the explorer Roger Frison-Roche made a crossing of more than a thousand kilometers on the back of a camel with the photographer Georges Tairraz II, in the heart of the Sahara, from Hoggar then Djanet in Algeria to Ghat in Libya. From their journey they brought back a large number of color films and documents. Among thousands of photos, they selected 47 images which reflect the various aspects of these immense spaces which occupy a third of Africa in the book "The Great Desert". “The Great Desert, 1000 kilometers on camelback” is the eponymous 85-minute documentary of this epic, released in 1950.
