Always the same, always different


Water mirrors in the landscape have magical effects. Whether by day or by night, they reflect the light and their surroundings, they are duplicating the beauty of landscape and sky that extends above them. Depending on the angle, weather and time of day, the effect changes. And it surprises us, every time again. Thus, [...]
