Photography in SG

Do you know that it is legal to take photographs anywhere in SG as long as you are in a public area? Perhaps many of us already knew about that, perhaps you don't. There had been discussions about this topic in a local photography forum a few months back. It was a whooping 20 plus-page-long thread. Apparently all local photographers were concerned about their rights as a photographer. I was just stopping by, hoping to gain some insight about the shooters' scene , but I gain more. So what I am trying to say is that, if you are shooting around in public in SG and was stopped by someone, you have the right to ask why. And if they ask you to delete the photos taken, you can refuse.
