Create exactly one high-detail reference photograph. This is one coherent image, without a contact sheet, labels, arrows or graphic panels.

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.

This place occupies the inward-facing surface of a completed rotating space habitat: an open bracelet 3,000,000 kilometres in diameter, with a 6,000-kilometre-wide living strip and mostly transparent, sloped retaining walls 1,000 kilometres high at its lateral edges. A natural star far outside the bracelet provides daylight. The local landscape is almost flat, with extremely slight concavity along its length. Air, weather, water and vegetation are real. There is no roof, dome, central artificial sun, supporting spoke or planet inside the bracelet. Ordinary transport infrastructure is mostly concealed. Show no sky-band unless this composition explicitly asks for one.

The desert artist is an independent machine citizen: a pale ceramic shell about 45 centimetres across, with one asymmetrical dark seam, no face, no rotors and no limbs. Its sandstone outcrop contains a dry-sand artwork: a small visible solar collector powers a lifting screw feeding polished channels, two shallow basins and one fine granular fall. A small gate can divert one stream between the basins. The machine manipulates that gate with an invisible local field; the gate moves without an invented arm or visible magic beam. Sand is dry granular material, with no liquid meniscus, glowing particles or water splash. The outcrop overlooks an immense pale salt desert.

Make one 3:2 50 mm-equivalent photographic view at human eye height of a pale ceramic machine hovering beside its dry-sand artwork on a sandstone outcrop. Show one small solar collector, lifting screw, carved channels, two shallow basins and the routing gate together in late sunlight. Granular sand feeds one basin. The desert behind is immense and softly distant. No person, bag, visible force beam, machine arm or sky-band. The work is intimate in scale despite its vast surroundings.
