The project was carried out in Spain in the city of Bilbao and is a representation of a path which intertwine visions cold and measured with representations related to emotions. The series is divided into diptychs: the photograph on the left is always one single shot that represents the space in geometrically rigorous way, the photograph on the right is a double exposure, the superposition of two moments, two points of view. 40 X 40 is a travelogue, a sequence in which you create a rhythm between geometry and geometry of the eye of the soul.
