KIEV, Ukraine (AP) -- Wearing a lead protective suit and placing his cameras in lead boxes, photographer Igor Kostin made a terrifying and unauthorized trip to the Chernobyl danger zone just a few days after a nuclear power plant reactor exploded in the world's worst atomic accident.
He came back home with nothing to show for his determination to document the crisis - the radiation was so high that all his shots turned out black.
But Kostin returned, and his work along with that of a handful of other daring photographers was critical to the world's understanding of a catastrophe that Soviet authorities were reluctant to admit.
