The event is held at the Heeren Atrium at Orchard Road from Oct 28 to Nov 4 where the 30 shortlisted pictures are displayed.
I just went there today afternoon. All pictures printed at A3 size by Canon i9950. There is a chance to vote for your favourite picture by writing the photographer's name on a form with your particulars and depositing it into a box. The prize is a Canon Powershot A400.
