It is undoubtedly a river that the photographer explores with the skill of an expert navigator, a river that slips down from the mountain peaks and silently rushes through humid jungles and deserted moorlands. It reaches the fields, crosses the wheat fields, avoids the cities, and travels through the villages of men. However, in those villages, we perceive the figures of shadows and the secret faces of the people. They are fleeting images, seen through open windows and, then, the river continues until it reaches the beaches of the coast, to dissolve into the ocean as if meeting its own destiny. These are photographs that make us feel much more than what we see. "In the highest regions, where the law of the wind prevails," says Harker, "a river called light is born".
