Yan's photograph 'Frank, Dali, China, June 2013' from Forest series has just been published in the new book Photography---A Feminist History by Emma Lewis. Mapping photographic developments against shifting gender rights and roles, Photography – A Feminist History shines a light on how photography has borne witness to women’s movements and made the causes for which they fight visible, and how, in turn, different approaches to feminism have given us ways of understanding photographs. Available from all major book sellers.
