Who knew that Frankfurt was a cultural heavyweight? Frankfurters, of course. But outside the Rhine-Main region, not so many are aware that there’s more to the city than its status as a financial hub. That was the thinking behind the Ray FotografieProjekte Frankfurt/Rhine-Main, which was founded in 2012, with the aim of showcasing Frankfurt’s artistic tendencies. And it’s worked. Starting this month (24 May – 9 September), the triennial is now one of the biggest and best-attended contemporary photography events in Germany. Highlights this year include a three-day opening festival, as well exhibitions from the world’s biggest photographers in 10 venues city-wide, including Martin Parr, Richard Mosse and Martin Liebscher, a German photographer known for his large-scale “panorama pictures”.
