I took a shot like this http://www.pbase.com/image/24723444). Odd, both of our shots were at 1/2s, yet you are at f8. In hindsight, I should have done that for the crisper detail. An interesting thing about this photo is the light streaks are striped -- a consiquence of the 60Hz AC? A lower fstop would have bloomed that together, I think. Interesting. Nice photography.
