These shots are great. Were you on a boat when you took these? If so how did you keep everything steady enough for that long?
Many Thanks ! ... Actually , I was on dry land on the opposite side of the Hudson , in Liberty State Park in NJ . Had the camera on a tripod with a remote release , got there a bit before sunset and staked out what I thought would be a good spot , set up , and did a series of shots every 15 minutes or so . Must have been 500 people there,some were just hanging out , some at the NJ 9-11 Memorial and a lot trying to get pictures of the towers of light. After a while I moved some distance down the walkway for the second shot . Here's one from earlier , just before sunset.
