At a time where the domination of visual is overwhelming, is it still possible, or even necessary to "visualize" people and things? The answer might be found in a kind of mediation, in our ability to create a meaningful transparency between images and their referents. In this regard, photography faces a decisive moment, forcing a new definition of the "documentary" category. Rather than offering more images of reality, it is now time to take into account the multiple realities of the photographic image itself. From this point of view, Wolfgang Tillmans is one of those who endlessly create images in total harmony with the complexity of contemporary life.
