How do you approach a stranger on the streets? How do you ask to take a photograph without speaking the language? What seem to be barriers at first make it easier in the end. You just ask. Its easier to speak a few words, but it works just as well without. You show the camera. They gesture to go ahead. There’s only a single exposure. Nobody can see it, because its an analog camera and there’s nothing to talk about, since we don’t share a common language. A handshake. No words needed.
Можно (мozhno) is russian for “may I?”
