No worries mate. Glad you were able to enjoy Vivid. I went for the first time this year too... managed to get a glimpse of the installations around The Rocks area and the Opera House.
Quite a "diverse" event, I thought, as there were many other attractions apart from the light installations. Can't say I've ever seen Sydney so crowded, even more than on NYE.
As for the photos... haven't even touched the camera since... hope there might be one or two decent shots, when I eventually get to them
