The Tate Britain is currently showing a major retrospective of the work of the photographer Don McCullin. A vast collection of his work spanning the last 60 years. The exhibition is broken down into sections, introducing the events behind the images – the division of Berlin, the Troubles in Northern Ireland, Vietnam, Biafra and more. Many of the images are captioned with Don’s thoughts and memories from the time, giving an insight into the difficulties of documenting some truly tragic scenes.
