Here are the results...
Team 1 was made up of David Bunting, Mirko Marcato, Lise McGreevy & Andrew Molloy.
Team 2 was Emmett O'Mahony, Paul Stewart & Sean McKeown.
All edits were done "in-camera" meaning the teams had to plan their shots very carefully to make the most of the 3 minutes allocated - and no post-production software was used.
Update 17/06/13: Emmett O'Mahony and Paul Stewart got in touch last week to say they'd developed their work further. The latest version of their film now includes narration and some stunning new footage they shot of the building.
Our thanks to Jan Carson at the Ulster Hall who made this event possible, Mervyn Smyth for a guided tour of the Belfast Exposed photography archives (a great resource for community film-makers) and of course Paddy Cahill for making the journey up from Dublin to provide his expertise on the day.
