In Seattle, each night during the Christmas season a large Yacht with carolers (the Christmas ship) visit various public beaches around Lake Washington. Seattle boaters decorate their boats with lights and follow the Christmas ship to join in the festivities.
I shot the header photo above aboard the Shubumi, a large motor yacht, owned by a friend during a Christmas ship tour. This shot was taken on Lake Union looking South towards downtown Seattle. The Space Needle is on the right and the with it's Christmas lights strung from the restaurant level to the top. There's a small lighted boat just in front of use the the left of center. The lights in the sky are air traffic, some of which is in the traffic pattern for landing at Sea-Tac.
Shooting on a rocking boat in the dark a challenge. This shot is one of about 20 frames it took me to get this shot. ISO 800, F2.8 @ 1/6 sec. Taken hand-held in as close to the center of the boat as I could get to minimize port to starboard and fore and aft motion.
