How have artists, filmmakers and photographers shaped our understanding of wars and conflict? Journalist and writer Helen Lewis explores the recently-opened Blavatnik Art, Film and Photography Galleries at Imperial War Museum, London.

From No Man's Land to mushroom clouds, Helen discovers the people that have interpreted over a hundred years of conflict, in this specially-curated tour by James Bulgin, Head of Public History at IWM.

They are joined by Suzanne Plunkett, Reuters' Chief Photographer for the UK and Ireland, and a photojournalist for almost 30 years - and someone who can give us a first hand account of what it's like to be capturing a seismic event in the moment.

Objects Discussed:

Paul Nash, The Menin Road, 1919

John Armstrong, Pro Patria, 1938

War Pictorial News No. 21

Mushroom Cloud over Nagasaki, 1945
