Excess Baggage - 20/06/2009

John McCarthy talks to three professional travel photographers about their different experiences and approaches to taking particular kinds of pictures. Lisa Young works all over the world for both commercial and charitable organisations; Adrian Arbib takes politically conscious photographs of threatened tribes and ecological protest movements; and Bill Birkett is a photographer of hills and climbing, particularly in the Lake District. They compare notes on techniques, problems and aims in the fast changing digital age, and discuss what drives them on in difficult and dangerous conditions to capture the defining image of a place.
