The photographer Marc Atkins and I are working on a project called Fields of England. We go into fields we have known for a long time, and others we just know about, but have never seen: battlefields, minefields, deserted village fields, fields undersea, gathering places, burial grounds, places of execution, places where treaties have been signed – but this is a list of field-genres. If we have learned one thing, it is the limitation of genre. There are as many genres as there are fields. And almost as many Englands.
