The photographic work I've conducted at the Marignac swimmingpool in Lancy, during 2017, has opened on an exhibition of seven images chosen among more than a thousand. This exhibition, named "Natations et vertiges" has been made possible through a partnership between the cultural services and the road services of the city of Lancy, the APG/SGA (Société Genevoise d'Affichage), and the Marignac sports establishment management. The pictures are shown with Blueback posters printings, F4 format (89,5 sur 128 cm), and fixed on metallic sheet clipped in the F4 pannels. The posters will be destroyed or recovered once the exhibition closed.
