A photographic exhibition honouring photographers in the 1980s who defied martial law to expose the atrocities of apartheid is now open at the Nelson Mandela Foundation in Johannesburg.
Between States of Emergency highlights the work of 40 photographers working in South Africa from 21 July 1985 to 7 June 1990, when a series of States of Emergency were imposed to clamp down on anti-apartheid protests. The emergency regulations were continually refined to prevent the media reporting on these protests and the brutal crackdown that followed.
Here are pictures from the launch.
