I find it hard taking pictures of people, I feel like I am in their personal space and they are now in mine. It makes me uncomfortable. There is also the issue of whether or not to ask permission first. Once I have asked permission I feel the pressure to perform, I am no longer having fun and I am too self-conscious to focus on what's through the lens. If I ask permission afterwards there is the pressure of having something good to show for it, I have lost the discretion of going home and simply discarding anything that just didn't work.
This is Ivan Berg, I found him at the Gypsy Travellers Fair sheltering from the sun and playing a little guitar between customers. He and his family have been travelling around New Zealand with the Fair for more than a decade now - he photographs just beautifully and is one of my rare success stories.
