A bridge beneath a mountain

Create exactly one high-detail 3:2 landscape photograph. Render a single coherent moment, with realistic material detail and crisp water and foliage appropriate to a still exposure. Keep usable image content around the subjects. Do not make a storyboard, contact sheet, split screen, motion-blurred simulation, crop guide, label or diagram. Any normalized positions specify composition within the full image, with x increasing rightward and y downward; do not render those numbers.

Use photorealistic observational cinema, natural exposure and tactile material detail. Use rectilinear optics, soft highlight roll-off and very fine restrained grain. Preserve the difference between cool daylight, dry late sunlight and blue-black night; warm rooms have practical amber light. Give distant scenery atmospheric depth and keep foreground objects physically solid. People are comfortably dressed and absorbed in ordinary life. Architecture is personal and spacious. Avoid glossy resort advertising, decorative science-fiction clutter, excessive lens flare, fisheye distortion, posed glamour, captions, lettering, logos and borders.

The space habitat is a completed open bracelet 3,000,000 kilometres in diameter. Its 6,000-kilometre-wide living surface faces inward, holding land, water and atmosphere. Sloped, mostly transparent retaining walls rise 1,000 kilometres at the two lateral edges. Its exterior structural base faces vacuum. A real star outside the bracelet supplies light. The central Hub floats independently, with no spokes, and is too small to resolve in these views. There is no central sun, planet, enclosing dome or solid disk filling the opening. The spin is roughly day-long and has negligible visible rotation over a few real-time seconds.

The vehicle is a sealed express car running below the exterior base of the habitat. Its large oval window has a satin-grey rim. Inside are a blue-grey upholstered bench and exactly one securely rooted fern in a fixed low planter. Transparent lower side panels and a section of the floor reveal sparse stars in actual vacuum beneath the vehicle. Through the upper glazing, the immense smooth grey engineered Plate base lies overhead, marked by fine guideway grooves and occasional hanging access masts. The inhabited landscape is out of sight beyond that base. The order is landscape, structural base, vehicle, open space. Keep pressure glazing intact, exterior reflections weak and the cabin comfortable. There is no atmosphere outside, open balcony, star pattern printed on the floor, glass ceiling showing a sky above a train, geological planet or thick mass of natural rock.

No people or bag.

PHOTOGRAPH
A stable 28 mm-equivalent photograph from a sealed express car beneath a colossal hollow mountain structure. Distant engineered ribs rise into the upper half in subdued reflected light. A fine attached transit bridge runs from the lower middle toward a far anchor near x=0.67, y=0.43. Small nearer fittings provide scale without a giant foreground train. Sparse stars remain visible below the opening; an oval window rim and fern sliver occupy lower left. The bridge spans a hollow engineered volume, without thousands of kilometres of solid natural rock. Preserve dark tonal detail and a visible attached route. No lava, coloured spotlights, battle or stellar streaks.

Render only the stated moment. Preserve a single internally consistent perspective and natural proportions.

The composition looks outward through a small corner of the window into the hollow volume. The oval rim and a small fern sliver occupy ONLY the extreme lower-left corner, together less than five percent of the frame. Do not reproduce an entire furnished car interior or a huge oval window filling the picture. The main view shows an immense hollow mountain interior supported by far-separated engineered ribs and arches soaring into darkness, with a hair-thin attached transit bridge receding from lower middle to a tiny distant anchor near x=0.67,y=0.43. Actual empty vacuum and sparse stars are visible below the bridge. The ribs define a cavernous open volume, not a close flat ceiling. No giant foreground bridge, solid rock planet or lava.
