Until July 27, the Parisian Rabouan Moussion Gallery presents “Palm Springs,” a series of photographs taken by Dutch Erwin Olaf.  He exposes, in broad daylight, the new – darker – face of this Californian city. This exhibition marks his 40-year career, an anniversary celebrated by the publishing of “Erwin Olaf: I Am,” the first monograph dedicated to the photographer whose approach remains firmly sociological.
