There are NO Photographer SPECIFIC laws in Singapore as there are no laws SPECIFICALLY governing Talking to Strangers in Public and Use of optical equiptment .... these are normally covered under BROADER guidelines and laws
Yes we just go snapping around .... at least I have been for the last 30+ years (without a copy of the Constitution in my back pocket)
And yes too, seems like many are not interested in helping because this subject comes up every couple of weeks.
Photographing in public - SO MANY situations can occur...... you'll need parliament to pass an Act several thousand pages thick just so photographres know what they can and cannot shoot in public ? Look at OTHER side of the coin .....so far, it is not illegal to take photos in public ......... there is NO LAW that says you cannot take photographs in public. ( unless the building/location has No Photography notices which are to be respected) ....... THATS ALL, work with this knowledge .! Photographers who make a living taking photos in public (eg those who shoot for news agencies, newspapers etc etc) in Singapore work with this knowledge too.
Yes MANY people do not like their photos taken in public by strangers like you and me...... BUT that is a personal matter and a decision you and me will choose to respect or not respect ...... still it is NOT illegal to take photos in public.
Whats the WORST penalty ? Jail/Fine/Caning/Hanging? At worst you'll be asked to delete your images or get whacked physically ..... if you get assulted, now the assailant has broken the law and you call in the police.
It is still not illegal to take photos in public..... just that you or me just pissed someone off enough to get whacked. Even with a law in place, some unhappy person is still going to throw the law to one side and attack or assult you or me.
If one does not have the aptitude or is paranoid about shooting in public, do not look for laws to cover yourself.
Cant point you to help more but below are just some discussions
