Nine Barrow Down, Isle of Purbeck ‘The process of taking them is quite dynamic. I have to move quickly for a number of reasons – to catch the light if it is changeable, to catch the right angle on the rock as it follows its trajectory across my viewfinder, and also so I don’t bore whoever I am with, since these photographs are always taken while I am on a walk with a friend. The resulting photographs, by contrast, always seem serene and static. I am not sure they reflect the process that has created them. They reflect something else altogether.’
