I revisited the photos from my visit to Marina Bay in which I made a lot of long-exposure images. In this place, nobody cares how many photos I take since people don't mind me standing in the middle of their way. In all of the images, the shutter was open up to 30 secs.
Usually, I will take a bunch of photos on the same spot or around to give me an option during the post-processing. After taking the shot, the next thing for me to do is to inspect the photo if it's something of quality. I will only move on to another when I'm happy with the result.
Here are some of the long-exposure shots taken that night...
