Long exposure takes a lot of patience and practice.  BUT, if you believe that you can, and you give yourself enough time for moments of trial and error, you won't be disappointed! I believe that you all will share incredible long exposure images as we continue through the week.  If you've already felt frustration, keep with it, and I would bet that by the end of the week, you'll feel like a pro! This was taken with a twenty second exposure time at f/20, ISO 200 (and, of course, a tripod that I had to believe would stay sturdy enough while taking such a long exposure).
