Hello there & thanks for your comments.
My settings are f9, 30secs & at ISO 200 at A-mode & using D5100 nikon. Hope this helps.
A must for night photos will be a steady tripod also the best time will be to take during the "blue" period which is about 1930-1945 hrs locally ( which unfortunately it was raining on Saturday). If you will like you can check out my other postings here which shows from early "blue" to dark .. http://www.clubsnap.com/forums/night-photography/976751-singapore-blue.html
