What did it take to capture 20th Century warfare on film - and how were they used in the war effort? Geoff Norcott joins curator James Taylor for a personalised tour of the artworks on display at the Imperial War Museum, London.

From reconnaissance missions by air to the cameramen risking their lives on the ground, images from this time have endured in our consciousness and shaped the way we have recorded war since. Expert Toby Haggith explains how the increasing sophistication of filmmakers impacted our view of the world.
