'Climate change is a really important issue for Oxfam this year, so we wanted to do something a bit different, with the ultimate aim of producing innovative content for our website,' says Oxfam's multimedia content editor Ben Beaumont. 'Everyone here is delighted with the results - the quality and depth of using a digital stills camera to do video really shines through. You need that look to make people stop and watch a film for two minutes, and to make them really feel what life is like for this community. People have told us they haven't seen anything like this from an NGO before.'
