In 2002, the great reporter Hans Silvester discovered the Omo Valley. Initially, he went there to meet Lucy, the oldest human being. It was with Moulou, his irreplaceable guide, that he finally met the various local peoples. Fascinated by their way of life, he develops strong ties with the tribes. His photographs reveal the various body paintings of these peoples, attesting to the photographer's patience and the trust he has been able to inspire These pictures reveal their art, their generosity and the precarious balance they maintain with nature. These numerous photographs bring us closer to these people, along the banks of the Omo.

Retour De Voyage has selected these photographs which capture the great diversity of the paintings with a limited colour palette.
