Your personal paparazzi

For some strange reasons, I think this business can actually do well here in Singapore. I might even be interested to set up something similar. From MethodIzaz:

MethodIzaz is a unique photography experience. Subjects are unaware of the exact moment they will be photographed and of the photographer's identity. Instead, the subject is photographed completely naturally, living life as normal...

Using information provided earlier about their weekly routine, the photographer will arrive on the scene, and unseen, take shots of the subject. The subject will be photographed walking through the streets, going about their daily business. Without posing and artifice, the camera captures only the natural beauty of the person.

It's like having your very own paparazzi!
