Alcatraz Island, San Francisco
Green Over Concrete
On Alcatraz, a steel water tower and a weathered guard structure, seen through the plants that have moved in.
The famous version of Alcatraz is grey: concrete, steel, fog, the cellhouse on the hill. What surprised me was how green it is up close.
In this frame, the island's hard architecture shares the space with plants. A palm-like tree with spiky, sun-struck fronds arcs over the upper left, its trunk rough and grey. Bushes and leafy shrubs crowd the bottom of the frame, soft and bright in the foreground, their leaves blurred so they read as a wash of green and yellow. The architecture sits behind all of that, half hidden.
There are two structures. On the left, the steel water tower, painted dark blue-grey, a lattice of cross-braces and legs with a spiral staircase winding up through the middle to the tank at the top. On the right, a concrete structure with a pointed, arched balustrade along its top edge, its surfaces streaked with rust stains and patches of moss and lichen. It looks heavy and patient, the kind of concrete that has been rained on for a long time.
I shot it from low, looking up, with the plants between me and the buildings. That angle does two things. It puts the structures against a clean, pale blue sky, so their shapes read clearly: the open steel grid on one side, the solid concrete mass on the other. And it lets the foreground plants frame the scene, so you see the architecture the way you encounter it on the island, through and around the growth.
The contrast between the two structures was the composition. The tower is all lines and air; you can see the sky through it. The concrete is all surface; you can see the weather on it. Put side by side, framed by palm fronds and shrubs, they make a quieter picture of Alcatraz than the usual one, less about the prison's reputation and more about what time and plants are doing to the place.
I like that the most alive thing in the frame is the green. On an island built for confinement, the plants are the ones taking up space.
From the bag
Sony A7R III · Sony FE 16-35mm F2.8 GM II · 35mm · 1/1000s · f/2.8 · ISO 100
In bright sun at base ISO, f/2.8 gave me 1/1000s, more than fast enough to handhold and to freeze any movement in the fronds. Shooting wide open at 35mm was deliberate: the foreground leaves are close to the lens, and f/2.8 throws them soft so they act as a frame instead of a distraction, while the tower and the concrete further back stay crisp. ISO 100 keeps the blue sky clean and smooth, which matters when so much of the frame is open sky.
