Paul Winkler, one of Australia's foremost experimental filmmakers, has for over thirty years created beautiful, demanding, semi-abstract films using complex in-camera masking and multiple exposures. To achieve his rich and compelling images, he continually reinvents his approach and has designed a number of devices, including a matte-box image shifter. Experimental filmmaker Dirk de Bruyn comments, "In his films Winkler is meticulously transposing rules of architectural construction into the building of a visual edifice. These films are like ephemeral pyramids....What lies buried within the inner chamber of a Winkler film is the sarcophagus of Technique itself. For those entering there are innumerable pitfalls lying in wait for the unwary weaned on the warm milk of mainstream cinema." Retrospectives of Winkler's films were recently held at the Museum of Contemporary Art in Sydney and at Harvard Film Archive.
