It was a real thrill to be invited onto BBC London yesterday to be interviewed by Robert Elms about my City Guides exhibition on his superb London-focused show. I took along Peter Twist, one of the 26 Guides that I photographed for the exhibition and a specialist in fascinating Smithfield Meat Market tours. Robert’s perceptive and probing questions soon had us chatting in depth about the challenges of photographing this eclectic bunch of London obsessives. Do have a listen to this 15 minute discussion. We start at 01.32 into the show and end at 01.47.
