It’s the 21st year of the prize, and this year the shortlisted projects by Mathieu Asselin, Rafal Milach, Batia Suter, and Luke Willis Thompson all “reflect a shared concern with the production and manipulation of knowledge and systems of representation through visual formats”, say the organisers of the Deutsche Börse Photography Foundation Prize 2018. Mathieu Asselin (b. 1973, France) has been nominated for Monsanto: A Photographic Investigation, which was published this year by Actes Sud and exhibited at Les Rencontres d’Arles, and which has already won the First Book of the Year in the Paris Photo-Aperture Foundation Photobook Awards 2017.
