Tributes are being paid to one of South Africa's most-celebrated photographers, Santu Mofokeng, following his death at the age of 64.

The Soweto-born Mofokeng started his career as a street photographer in his teens, before becoming one of the greatest chroniclers of the struggle against the racist system of apartheid.

In 1985, Mofokeng co-founded Afrapix, an agency which defied the apartheid regime's restrictive media laws and supplied mainly black newspapers with photographs rarely published in the white-dominated media.
