With Invisible , a visual, photographic research project on the underwater seascapes of the Calanques, Nicolas Floc'h set out to capture the state of the underwater seascapes at a given point in time, between 2018 and 2020, by following the entire 162-kilometre coastline of the Calanques National Park in the Mediterranean Sea near Marseille in France. The black and white photographs, taken between the surface and 30 metres below sea level, in natural light and with a wide-angle lense, present a panorama of the natural and man-made landscapes and their transformations. With text contributions in French and English by Muriel Enjalran, Pascal Neveux, Gilles Clément, and Nicolas Floc'h.
