A new photography exhibition, 'Life Interrupted', has opened featuring photographs by acclaimed photojournalist Don McCullin on the impact of anti-viral drugs on HIV sufferers in Africa. The exhibition runs until 10 January 2005 at County Hall Gallery, London and is free of charge. There is also a very good online exhibition which also includes images from 'Cold Heaven', based on McCullin's 2000 trip to Sub-Saharan Africa. The photographs are given context by the stories associated with them (move your mouse over the pictures to access these in the online exhibition). McCullin's work is highly atmospheric and conscience-pricking. Black-and-white still photography presents a powerful vehicle for combining reportage and aesthetic, of which I think McCullin's photographs are exemplary.
