Demonstrating the power of Slow Cinema, Cielo abierto is a portrait of a difficult meeting of worlds. A Peruvian father labours patiently, chipping at the white volcanic stone that forms an extraordinary landscape. His son is part of the modern world: he uses cameras and drones in order to create the digital model of a church on a computer. Separated by the mysterious death of the wife/mother figure in the family, these men do not connect. And yet their paths cross in a ghostly manner, as do their professions: each in their own way works with textures and volumes, sensations and perceptions. Can the realm of digital art recreate and revivify the old world? Can it also awaken hearts grown lonely and cold?
