The Getty Institute is so much more than the glamorous LA Getty Center. There’s the Institute’s specialist research and conservation, particularly around the built environment, and this year an enormous global project has focused on the architectural conservation of iconic structures around the world. No surprise that one key source of study is the Sydney Opera House and the delicate work undertaken over its 50 years to update the cultural centre, making it compliant with contemporary civil and safety regulations while maintaining Danish architect Jørn Utzon’s vision. Afterglow was the Sydney producer for six video presentations on what the Opera House means to the city and NSW, how to approach Utzon’s legacy, and the tricky conundrums that arose in improving acoustics and safety issues and replacing worn materials.
