The exhibition catalogue Stralau takes the viewer on a voyage of discovery through the oeuvre of the Thun-based photographer Christian Helmle. In his photographs, Helmle deals with themes such as nature, architecture, and humans, whereby structures and topographies also appear time and again in his expressive works. The photos are accompanied by a foreword by Helen Hirsch, Director of the Kunstmuseum Thun, as well as contributions by Konrad Tobler and Alisa Klay. While Tobler's essay examines the tectonics and dynamics in Helmle's photographs, Klay explores the photographer's latest series of works as well as people in the urban social environment. The catalog is published on the occasion of the eponymous exhibition at the Kunstmuseum Thun and offers viewers a comprehensive insight into the artistic work of Christian Helmle.
