than I’d done for months. Partly because I had a purpose. But also because I’d closed the door on the world outside. Now I could think of my father. I began to consider how he had coped with difficulty. Putting a lens between himself and the world was a defence against more than physical danger: it shielded him from other things he had to photograph: awful things, tragic things; accidents, train crashes, the aftermath of city bombs. He’d worried that this survival strategy had become a habit. ‘I see the world through a lens,’ he said once, a little sadly, as if the camera were always there, stopping him getting involved, something between him and the life that other people had.
The chaffinch was calling again. How you learn what you are . Had I learned to be a watcher from my father? Was it a kind of childhood mimicking of his professional strategy for dealing with difficulty? I kicked the thought around for a while, and then I kicked it away. No , I thought. No . It was more I can’t think that than It’s not true . All those thousands upon thousands of photographs my father had taken. Think of them instead. Each one a record, a testament, a bulwark against forgetting, against nothingness, against death. Look, this happened . A thing happened, and now it will never unhappen. Here it is, in the photograph: a baby putting its tiny hand in the wrinkled palm of an octogenarian. A fox running across a woodland path and a man raising a gun to shoot it. A car wreck. A plane crash. A comet smeared across the morning sky. A prime minister wiping his brow. The Beatles, sitting at a café table on the Champs-Elysées on a cold January day in 1964, John Lennon’s pale face under the brim of his fisherman’s cap. All these things had happened, and my father had committed them to a memory that wasn’t just his own, but the world’s. My father’s life wasn’t about disappearance. His was a life that worked against it.
He’d come home from work strangely disheartened one winter evening. We asked him what was wrong. ‘Did you see the sky today?’ he said. He’d been walking through a London park on his way back from a press-call. It was deserted but for a small boy playing by a frozen boating lake. ‘I said, “Look up, look at that. Remember you saw that. You’ll never see it again.”’ Above them both was a vast tracery of icerings and sun-dogs in a wintry, hazy sky. A 22° halo, a circumzenithal arc and an upper tangent arc, the sun’s light refracting and cutting the heavens into a complicated geometry of ice and air and fire. But the boy didn’t seem interested at all. Dad was baffled. ‘Maybe he thought you were one of those strange men,’ we sniggered, rolling our eyes, and he looked embarrassed and faintly cross. But he was so very sad about the boy who didn’t see.
Now that Dad was gone I was starting to see how mortality was bound up in things like that cold, arc-lit sky. How the world is full of signs and wonders that come, and go, and if you are lucky you might see them. Once, twice. Perhaps never again. The albums on my mother’s shelves are full of family photographs. But also other things. A starling with a crooked beak. A day of hoarfrost and smoke. A cherry tree thick with blossom. Thunderclouds, lightning strikes, comets and eclipses: celestial events terrifying in their blind distances but reassuring you, too, that the world is for ever, though you are only a blink in its course.
Henri Cartier-Bresson called the taking of a good photograph a decisive moment . ‘Your eye must see a composition or an expression that life itself offers you, and you must know with intuition when to click the camera,’ 2 he said. ‘The Moment! Once you miss it, it is gone for ever.’ I thought of one of these moments as I sat there waiting for the hawk to eat from my hand. It was a black-and-white photograph my father had taken many years ago of an elderly street-cleaner with a white goatee beard, wrinkled
