Every building makes us raise our eyes to the sky. And search for something, or hope, or dream. Sky is an intrinsic part of a construction and instinctively, when looking up to a building, we have the impression that we could reach the sky if following the path the building opens in front of us. By using the technique of long exposure I tried to find a way of connecting the building with the sky above and bring together the stability and permanence of a construction and the ephemerality of the sky and I did that by following the path created by the moving clouds that guided me from the building to the sky.
