Thanks for clearing things up vince, yes the whole model release issue will make or break my project, so i'm very anxious to find out about such issues in singapore.
After going through the Intellectual Property Office of Singapore website, this is the closest i can find from their FAQ:
I provide photography services. Do I own the copyright to the photos that I take for my clients? If I don't, is there any way that I can own the copyright? I want to showcase the best photos in my website and brochures.
In general, clients who pay for your services own the copyright to the photos taken. However, you have limited rights in that if the photos are required for any particular purpose (e.g. a corporate client wants glamour shots of the senior management, to use in its annual report) made known to you in advance. Your clients should tell you and you are entitled to prevent the photos from being used for other purposes.
In practice, however, many photographers have their own terms of engagement with clients. The parties are free to have their own agreement, which automatically overrides the above default position. Thus, for example, you and your clients can mutually agree with your clients that you will own the copyright in the photos but that your clients can use the photos for certain purposes; or that your clients own the copyright but you have the licence to reproduce the photos in your website and brochures.
It doesn't say anything about non client-photography issues. As such is the problem in my case, as well as a lot of casual photographers i think.
