The decisive moment: a cantilevered stone spiral stair seen straight down its open well, the treads unwinding into eleven diminishing turns, a single brass handrail catching the light on every revolution, one small pale figure standing still on a landing four turns below. A daylit municipal stairwell, lime-plastered walls, a tall clear window at the top spilling light down one side, unbranded, no readable signage. Wide shot composed as a centred spiral with the well's vanishing point just off the middle, bird's-eye looking straight down, 24mm lens, deep focus. Single-source daylight raking across the treads with deep shadow on the inner curve, cool neutral grade with a warm reflected bounce off the plaster, real stone and plaster texture, photorealistic, extreme detail. Negative: blurry, warped text, readable signage, distorted geometry, oversaturated, watermark, no digital sharpness, no CGI gloss, no over-smoothed textures
