Night time don't need the big stopper la boss. Unless you are crazy enough to wait for a few hours. :bsmilie:
Always remember that the exposure will go up exponentially whenever you use the big stopper.
The longest I have ever done was 45 mins. This was shot in Perth (without any filters of course).
Cool! nice picture! wah 45mins very long leh.....so you just stopped down to acheive the long exposure?
