[QUOTE="salukfan111, post: 516331, member: 39212"] 1. shoot off tripod 2. shoot manual 3. use 500 (600) rule. Your built in crop factor might mess you up. Shoot with increasing exposure length to see when the stair trails start and cut that in half. Use that cut in half number to figure what number to divide your focal length into. 4. use prime lens (nikkor 20 f/1.8 set a little lower than 1.8 is really good but there are better - I've found a Tamron 15-30 f/2.8 at 15mm almost as good as nikkor 20mm f/1.8). If you're stuck with some sort of zoom set at minimum. 5. use a high iso (as high as you can). If there is too much ambient light keep your exposure long and reduce iso until the results are exceptable. Your camera will have a iso limit where going above will have a bad effect. 6. use a shutter release. 7. set color temp around 3800-4000K [url=http://www.jshine.net/astronomy/dark_sky/]Dark Sky Finder[/url] (there will be a simliar site for your area) dark green will produce acceptable result but blue and gray are what you are really after.
