On Growth and Form brings together the work and process of photographers Holly Birtles and Tim Burrough. Using Sir D’Arcy Thompson’s 1917 book that looks at how things grow and the shapes they take in nature and biology, Birtles and Burrough develop a visual response to the content and their practise. Swaying between juxtaposed spreads and sequences of visual narrative, this is the second edition in a growing sequence of works looking at form and growth.
