Photographer and video artist. He started his career as a sculptor, but gained renown by making abstract videos using a technique he calls feedback, in which a simple electronic appliance such as a TV set or video player is connected to a camera to generate images. The artist does not attempt to control the outcome at all. On the contrary, chance is considered to be a part of the artwork. He has also made the photograph series Espejismos, in which he seeks to denaturalize the act of seeing, revealing implicit layers to this seemingly spontaneous action. He has featured in several festivals and won several prizes. The main feature of his later documentaries is the camera’s presence in the set. Lives and works in Argentina.
