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. The images, taken between 0 and -30 metres deep, in natural light and with a wide-angle lens, present a panorama of the natural and man-made landscapes and their transformations. The black-and-white photographs show the sea as it offers itself to the eye.
