Technical Direction Company (TDC) will light up St Mary’s Cathedral in Sydney with video projections this Christmas.

 The display, which will run up until 25 December, uses a 75-metre backdrop to project images of up to 17,640,000 pixels.

 “TDC projection video designers created special code and electronics so that the entire system is ‘virtually wired’ and controllable using an iPad device,” said TDC managing director Michael Hassett.

 “Remote monitoring is something TDC has been perfecting for a number of years. It allows for rapid programming, fixes issues remotely in real-time, uses a CCTV camera on-site to see what’s happening and allows scheduling of different shows and operation of each days events.”

 AGB Events was responsible for creating content for the event, which will tell the story of what Christmas means to Sydney.

 Anthony Bastic, director at AGB Events, said: “The animations have three themes based around life and light. TDC are back this year with bigger and brighter projectors. Their expertise enables us to have unlimited creativity with our artwork.”
