This show is causing a bit of a stir in Paris, primarily because the photographer being showcased, Andre Zucca worked for a Nazi propaganda magazine "Signal" during the Occupation at the height of WWII. The strange twist is because of his rare access to color film he was able to document the Paris of those war years. Of course as a 'propogandist" he chose to depict Occupied Paris in a far more romantic way that the reality would suggest.
As David Lewis in Artforum outlined, "Mainly the images depict fashionable girls sporting sunglasses and cycling and swimming, working-class and bohemian antics, and the magnificence of Parisian architecture and streets. The Parisians appear better served under the Occupation than history, or myth, would have it. It is for this reason that the show has caused such a scandal. Officially, controversy broke out over a supposed lack of curatorial sensitivity—the photos were at first displayed without much historical information, which was then added—but what is in fact tough to stomach is the lesson these photos offer about indifference, especially in the face of tragedy."
All which just serves to underscore the ever shifting values of truth in a photograph.
