I think this has to be one of my favourite photos I have ever taken.  It is the Melbourne CBD skyline taken from Southbank (Melbourne, Australia).  I had spent the day walking around Melbourne just taking shots of gardens, graffiti in the lanes (which Melbourne is famous for) and whatever else took my fancy.

I had my tripod with me so thought I would try out some long exposure shots that night.  This was taken around 8:30pm sometime in March 2012.  I used my Canon 60D and it was a 30sec exposure.  I have not manipulated the shot at all in post-production as I just loved the colours as they were.
