With spring coming, prizes seem to flourish everywhere. The Deutsche Börse Photography Prize chose the intimate space of the Photographers’ Gallery in London to showcase its four shortlisted artists. This year’s selection presents a vast and eclectic panorama of contemporary practices in Europe. While Richard Mosse reflects on the genre of war photography, Lorna Simpson is more concerned with the concept of performance. As for Jochen Lempert, she seems to follow a more experimental and abstract path. Lastly, Alberto Garcia-Alix shares with us an important photographic diary of his life over four decades.
