I played around a little bit on my way home from dinner tonight.  I love long exposures is a city. Lots of color, shapes and starburst.  Here is one from Tonight. Details of this shot are ISO 200, f16 and 13 seconds.  This was shot RAW with in camera jpeg conversion.  I wish I had more foreground on this shot but I had just the 35 mm equivalent lens on it and no tripod.  The camera was resting on a bridge support so I had only minor options for framing.
