Ah not that easy siah, if so everyone wld be a docu/film-maker
:)) are u a film maker?
Are you going to make that documentary, by standing aside
and just video the action quietly? You must want to tell a
story.
These people are at any hawker centres, go out
with your pen and note book.
Get started with that, and one thing will lead to another.
Once you got an idea of what 'can collecting' is like. You then
decide how you want to tell the world, or least
Singapore. Tell about their lifestyle, how pityful, hard,
their choice, unfortunate circumstances, bad government, no family
support, ungracious public, you choose the theme, you can even
decide on a comedy, present a humourous aspect of can
collecting.
Tell a story, choose the medium.
