There is no double exposure or digital manipulation in these photographs. This series explores glass as a membrane. Not the glass added as a resource during the photographic act, but the one that is already an integral part of the space to be studied. The glass with its interferences: the dirt it has acquired, the residues it has retained, the marks left by the water and the humidity. From the observation of the effects of light on this surface, the glass revels itself as a membrane. As a layer that holds and lets pass, that separates and connects, creating its own and particular atmosphere.
