Elegant Spiral Staircase

A high-end architectural photograph of a sweeping curved staircase inside a luxury residence. Broad steps made from pale ivory marble rise beside a seamless warm-white plaster wall, accompanied by a slender brushed-brass handrail. A circular skylight casts one soft geometric pool of sunlight across the stairs. Photographed from the base with a 24mm tilt-shift lens, physically accurate perspective, realistic stone texture, elegant minimalist composition, no people, no furniture, no artwork, no text. Vertical 4:5.
