Jochen Gerz
The video works of the conceptual artist Gerz were from the very beginning critical engagements with the apparent and indirect understanding hat is generated by images in general and the technological media in particular. For his first video work Rufen bis zur Erschöpfung he positioned himself 60 meters away from a camera to which he untiringly calls out, “Hallo.” Video here is shown as a mechanical apparatus that stands in contrast to the performativity of calling out.
