Photographer and film-maker Harry Hook's documentary 'Photographing Africa' details his travels around the African continent to capture photographs of remote tribal communities.
Hook grew up in Sudan and Kenya, and over the past four decades, has carved a prolific career out of documenting life in Africa.
The central storyline in the documentary concerns Hook's search to find five Samburu tribal women whom he photographed nearly 30 years ago. Curious about how their lives may have changed with the times -- and eager to give them a copy of his photographs of them -- Hook decides to try and track them down.
It's no easy task however, as the women belong to a semi-nomadic tribe in Samuburuland, a region that is roughly the size of New Jersey state.
The documentary will air on BBC Four.
