William Kentridge – History of the Main Complaint
He used a technique that would become a feature of his work – successive charcoal drawings, always on the same sheet of paper, contrary to the traditional animation technique in which each movement is drawn on a separate sheet. In this way, Kentridge’s videos and films came to keep the traces of the previous drawings.
Thanks Robert.
