Re: Architecture + Photography = Job???
I work often with photographers for architecture.
I do not know what the situation is like in Singapore, but here you need to be rather good to make a living out of it. Some specialise for real estate agents, some for architects, some are better on interiors, some better exteriors, details etc.etc. etc.
If you realy want to make a job out of it, all I can advise you it to study photography. For now, start making photo's of buildings, and try to find out if you're talented enough. In the long run, you need good equipment and most of all contacts, because you need work.
Think carefull about it, if you need help with critiques for your photo's, send me a message.
