Since May 2018 a touring exhibition has been taking place of work from the photographic studio of Rudolf Sandalo (1899–1980). With an impressive and informative bi-lingual catalogue that includes high quality reproductions of nearly 280 photographs, it is worth trying to visit it at the City of Prague Museum, where it is still due to be on display.[1] Sandalo is little known outside of the Czech Republic, but he is noteworthy as the author of an extensive portfolio of photographs of the modern architecture that was built in Brno in the 1920s and 1930s. Almost single-handedly, he shaped the present-day image of the city as a major centre of central European modernism. This exhibition is important, not only for its attention to an oeuvre of great significance for Brno and Czechoslovak interwar culture, but also for the wider questions it raises about modern architecture and the role of photography in shaping how we see it.
