I would like to thank my friends, students and colleagues in the fields of photography and visual studies for information and ideas: especially Charlie Meecham and Kate Mellor of Outsiders Photography; Amanda Harman, Paul Stanley and Blu Tirohl; Maureen Thomas, Dominic Power and Helen McGregor of the National Film and Television School; and Alastair Haines of the Eastern Arts Board. Many of the basic insights of photographic practice were developed during my freelance work with BBC Television: I am indebted to the experience, professionalism and friendship of the News and Current Affairs staff. I would like to thank the staff of The Guardian, especially the picture editor Eamon McCabe and photographer Dave Sillitoe. I am also very grateful for the patience and attentiveness of my editor at Routledge, Rebecca Barden. Special thanks must go to my wife, Sandi Wilson, who provided moral support, advice and tolerance to see me through the trials and tribulations of writing the book.
