This shot was a little tricky because I wanted to catch the entire strand lit up (which requires timing, as it's synced to some music) as well as capture the falling snow as best I could in the limited light. I've found I usually need about 1/250 to do so.
Which of course causes issues because the entire strand is never really fully lit (as you can see at the top right.) Oh, and it was 0 F (-17 C.)
