FIELD NOTE — HARBOUR LIGHT STUDY, 06 OCTOBER At 07:14 the sun clears the Rimutakas and the harbour becomes a problem of geometry. Every window on Lambton Quay is briefly a mirror. Every mirror is briefly a mouth. The people inside do not notice. They are facing each other, which is another kind of light. I have been measuring the angle at which a conversation becomes a classroom becomes a conversation again. It is not fixed. It depends on who leans forward first. Cloud cover: 4/8 altocumulus, drifting NNW. Wind: southerly, 12 knots, smell of salt and diesel. Visibility: unlimited except where it matters.
