Ilan Wittenberg wants visitors to his new exhibition of photographic portraits not to see subjects in front of a camera, but real people. To do this, he's asked those who sit for him to stare straight into his camera lens. It means visitors can't avoid making direct eye contact with people photographed around the world in their own homes or work places. Lynn Freeman asks Lynn why eye contact is so important in human connection. Ilan Wittenberg's exhibition Faces of Humanity opens at Parliament Building in the Beehive's Executive Wing on the 12th of May.
