On Photography asks what it means today for an artist to work with a living, breathing icon, like the actress Tilda Swinton. Tim Walker, the noted artist and photographer, is joined by his long-time collaborator, stylist Jerry Stafford, to talk about their work together with Tilda Swinton. Dr Nicholas Cullinan, Director of the National Portrait Gallery, London, moderates the conversation. 'When I’m scared of something or someone, that scare turns into being photogenic. […] The situation becomes very heightened and I become very alert and I then I think I make better work.' – Tim Walker Tim Walker is a photographer for Vogue’s British, Italian and American editions, as well as W Magazine and LOVE Magazine. Jerry Stafford is a writer and curator. He is creative director at Paris-based film production company Premiere Heure and personal stylist to performers Tilda Swinton and Gwendoline Christie.
