[Purpose]
Korean Han River nightscape photo, wide landscape composition for a polished travel editorial, city guide hero image, or social wallpaper.
Create a real Seoul night view with bridge lights, river reflections, distant apartment and office windows, riverside promenade details, and a subtle lived-in atmosphere around {장소}.

[Composition]
- Subject placement: {장소} as the primary landmark across the middle third of the frame, with the river occupying the lower 35% and skyline lights stretching through the upper 25%.
- Background treatment: deep night sky with faint haze, thin cloud texture, distant high-rise silhouettes, apartment window grids, and soft city glow behind the bridge.
- Spacing and framing direction: wide panoramic feel with a natural left-to-right flow of reflections, layered bridge structure, far-bank buildings, riverside lamps, and small real-world details distributed across the scene.
- Main visual elements: {장면} arranged to read immediately as a real Seoul night view, with reflections, shoreline lights, occasional boat light trails, and promenade elements leading the eye toward the bridge.
- Foreground realism: include subtle near-bank details such as a dark railing edge, stone embankment, riverside path, bicycle-lane marking, small lamp posts, or a few tiny pedestrians in silhouette, kept secondary to the river and bridge.

[3. CORE STRUCTURE]
- Foreground/lower frame: dark Han River surface with long mirrored streaks of LED and streetlight reflections, broken by gentle ripples, small current patterns, and slight wake marks for photographic realism.
- Mid frame: {장소} anchored prominently, with bridge structure and/or nearby riverside architecture clearly visible, lit by dense points of city light; include believable support columns, cables, road lamps, and small vehicle light traces where appropriate.
- Upper frame: {시간대} sky treatment, deep navy-black with faint atmospheric glow above the city line, thin cloud bands, and subtle urban haze rather than a flat empty background.
- Light layer: {조명} rendered as distinct practical sources—bridge LEDs, building windows, promenade lamps, passing car streaks, boat lights, and their reflected trails—without turning the scene into an artificial neon wash.
- Human presence: if silhouettes appear, keep them small and secondary near the lower edge, promenade, or far bank, facing the river or walking along the path, with no facial detail.
- Real Seoul cues: add convincing riverside context such as Banpo fountain lighting if relevant, Yeouido office towers, apartment blocks, Namsan-like distant glow, river cruise traces, or tiny Korean wayfinding signage on the promenade.
- Color emphasis: {컬러} should dominate through contrast between cool dark water and bright neon/city highlights, with amber accents around bridge lamps, riverside lighting, and distant windows.
- Composition logic: {구도} should guide the eye from foreground reflections to the landmark and then into the city skyline, maintaining a balanced travel-photo look with depth, atmosphere, and natural urban density.
- Aspect framing: {비율} landscape presentation with crisp detail across the full width, suitable for banner, editorial header, or wallpaper use.

[4. STYLE RULES]
- Typography: not a designed text-overlay image; any visible text should be incidental real-world Korean signage only, such as tiny “반포한강공원”, “여의도”, “한강공원” wayfinding, bridge road signs, or ferry signage, rendered accurately and naturally in perspective.
- Color palette: {컬러} with deep navy #09111F, midnight blue #132238, cyan #39D5FF, electric blue #4C7DFF, warm amber #F2B35E.
- Photographic edge treatment: natural full-bleed camera frame with realistic lens falloff, gentle atmospheric contrast, and subtle separation between dark water, bridge geometry, and skyline lights.
- Detail density: include believable city texture—window patterns, traffic lines, bridge rail lamps, riverbank trees in shadow, safety lights, and reflective wet surfaces where appropriate—while keeping {장소} instantly readable.

[5. VISUAL STYLE]
- Camera / lens: full-frame mirrorless, Canon EOS R5 with 24mm wide-angle at f/8, tripod-stabilized long exposure for crisp bridge geometry and smooth but still natural reflections.
- Lighting: city night illumination from bridge LEDs and riverside buildings, with mixed practical light sources, controlled glare, realistic specular highlights on water, and exposure balanced to hold detail in bright reflections.
- Color grade: cool noir base with neon cyan and electric blue accents, plus restrained warm amber highlights on bridge lamps, promenade lights, windows, and shoreline detail.
- Photographic quality: high-resolution editorial cityscape, sharp architectural lines, mild long-exposure motion in boats and cars, realistic noise in deep shadows, and natural atmospheric haze over the river.

[6. MOOD]
Seoul night travel editorial — a cinematic Han River skyline frame with the calm romance of a late-night walk, the energy of glowing bridges and traffic, and the polished realism of a high-end cityscape spread in National Geographic Travel or a contemporary Korean drama.

[7. CRITICAL]
- Korean text accuracy: no large on-image title required; any incidental Korean signage must use fully correct Korean with clean glyph rendering, e.g. “반포한강공원”, “여의도”, “한강공원”, or “수상택시”.
- Composition invariants: wide Han River nightscape, clear bridge/city/light-reflection relationship, no daytime elements, no distorted skyline, no fake landmark replacement, and {장소} must remain the visual anchor.
- Realism invariants: water must show believable ripple texture and reflection breakup; buildings must have varied window patterns; bridge lights must feel like practical Seoul city lighting rather than abstract graphics.
- Output should feel like a real long-exposure photograph taken from the riverside, not a poster, not a mockup, and not a simplified digital illustration.

[8. 🚫 PROHIBITED]
- Fake official seals / certifications
- Broken Korean characters
