I'm embarassed to say ... this shot was hand held using a 10D (set at ISO 1600, shutter speed 1/30th of a second). Credit needs to be given to the architect in charge of the lighting of the conservatory. He/she clearly knew what they were doing when planning for a nightime presentation. Its one of those things where you walk up the path, the building comes into view and you know you just have to take a picture of it.
