I watched the documentary last night, wonderful. I see McCullin as a documentary, war and landscape photographer, but I've never really thought of him as a 'street' photographer. Of course his 'street' photography is very much documentary, and shows one to be almost completely distinct from the other, something I've never really thought about before. Most street photography you see on forums and so on seems to be completely mindless, his work is full of commentary and narrative.
He photographed in contexts quite familiar to me, but I would never have thought to do so. I absolutely love his way with the people he photographs, he takes a genuine interest in them.
I saw his retrospective at Hauser & Worth in Bruton two or three years ago, mainly his early and war work, only a few landscapes. The prints are mind blowing. You feel pretty wrung out afterwards.
