I shot a pano of the Christmas lights at Confederation Square in Ottawa, Canada. The trees with their blue lights nicely contrast the illuminated cenotaph and the Tomb of the Unknown Soldier. East Block of the Parliament Buildings can be seen in the background on the left and the Chateau Laurier Hotel is on the right side.
As a side-note; Yousef Karsh, the renowned portrait photographer lived and had his studio in the Chateau Laurier for a number of decades. http://www.karsh.org/#/the_man/biography
I started with 9 RAW images to build the pano and white balanced on the snow away from the blue lights. Exposures were 4s at f/4.5 at 100 ISO with the f/2.8 24-70 Nikkor set at 24mm. This is a fairly busy site, so assembling the images took some time waiting for people to move on and road traffic to not interfere with the shots.
