Chasing the Blue Hour

There is a stretch of evening, roughly eleven minutes in high spring, when a garden stops reflecting the sky and starts agreeing with it. Green drains out of the leaves; the petals keep their colour a little longer, as if reluctant to hand the day over. That is when I work.

Preparation starts hours earlier. The tripod goes out in daylight, the composition is settled over tea, and then there is nothing to do but wait for the light to come down to meet the frame. Impatience is the only enemy — arrive late and the minute is gone; fidget and the stems blur.

You do not take the blue hour. You attend it, quietly, and hope to be noticed.

Technically it is simple: a low ISO, a steady head, and the discipline to stop down even as the meter begs you not to. The garden gives you five or six honest frames. One of them, if you are lucky, is the edition — the one where every bloom holds its lamp of yellow against the coming dark.

The Blue Hour Irises study came from the middle frame of five, on the third windless evening of trying. I have stopped counting how many evenings end with nothing. They are not wasted; they are rehearsal.
