Tide Glass

The tide had gone slack an hour before the shutter opened, which is the only condition under which this plate works at all. Moving water breaks the column of light into a hundred short reflections; still water holds it as one unbroken shaft, wider at the shore and narrowing toward the horizon until it looks almost architectural, a pale beam laid flat on the surface rather than falling onto it.

Forty minutes is a long exposure for a subject that appears to do nothing. In that window the moon moved just enough to soften the column's edges without breaking its shape, which is the effect I was after: light with a slight blur at the boundary, as though it had been breathed on rather than drawn. The horizon line stayed hard the entire time, a single division between a sky that was still faintly gaining detail and a sea that had already stopped changing.

This was the first plate hung in the room, and it set the terms for everything that followed: one light source, one long sitting, nothing added afterward. The thin crescent that marks it in every listing is not decoration. It is the moon that was actually up that night, no fuller and no thinner than it appears here.
