Vivid, the annual lighting festival, includes performances from musicians, artists and an exchange of ideas in public debates. I participated in the "Collective Walking Tour" with Canon to get advice on the best spots to capture the beauty of the various projections--the light show on the Sydney Opera House probably being the most impressive one.
I had the opportunity to stand next to the light projectors on the cruise ship terminal.
In 2016, Vivid Sydney was extended to 23 nights from 27 May to 18 June and was attended by more than 2.3 million people according to Destination NSW. No numbers for 2017 yet, but there were many people...
The Harbour Bridge is bathed in light as well.
However, Vivid extents beyond just the iconic symbols of Sydney.
Impressive projectors provide the light for the various displays.
Vivid displays can be seen from many angles and view points.
