On November 23, Galeria Zé dos Bois receives professor and curator Sérgio Mah, a specialist in the fields of photography and contemporary visual arts, for a conversation with João Nisa about his exhibition ‘Primeiras Impressões de uma Paisagem’, currently on view at the gallery. The exhibition consists of a video installation based on material filmed inside the Águas Livres Aqueduct, on the outskirts of Lisbon, using one of its segments as a series of camera obscura devices. The conversation will focus on different issues raised by the exhibition, namely its form of conception, the working process underlying this project, and its relationship with other areas of artistic practice.
