빈티지 필름 톤 사진 변환

プロンプト原文

[Input]
- reference_image: {참고 이미지}
- language: Korean
- output_size: 1024x1024

[Purpose]
1-2 English lines: i2i vintage film tone conversion for a portrait, preserving the original person while recreating a specific era-inspired film look. Square-format social portrait with authentic analog texture, period-accurate color grading, and believable real-world details around the subject.

[Composition]
- Center the subject from {참고 이미지} as the main focus, keeping the original framing and facial identity intact, with the face occupying about 45-55% of the frame.
- Maintain the original pose implied by {자세·의상}; do not change body angle, crop style, or camera distance beyond the vintage-film reinterpretation.
- Use {배경} as the contextual setting, enriching it with plausible era-matched details such as worn walls, curtains, café tables, street signs, film-era furniture, window reflections, photo-album shadows, or everyday objects that naturally fit the scene.
- Apply {시대 결} to guide the overall era feel, while {필름 결} and {컬러 톤} define the final film texture and palette.
- If the source composition allows it, include a subtle analog-photo artifact such as an orange date stamp, small lab-scan numbering, or handwritten album-note feel near an edge, without covering the face.

[Core Structure]
- Base image preservation: keep the same person, same expression, and same composition framing from the reference, with only the film styling transformed.
- Subject treatment: render {참고 이미지} with natural skin texture, fine pores, flyaway hair, realistic fabric detail, slight film softening, and subtle analog halation around highlights; avoid beauty-filter smoothing.
- Era styling layer: translate {시대 결} into a convincing period-specific snapshot look, matching the implied decade through wardrobe feel, background cues, lighting behavior, surface aging, and tonal response.
- Texture layer: apply {필름 결} with visible film grain, mild color shift, gentle exposure roll-off, faint dust specks, tiny scratches, scan noise, faded edges, slight gate weave, and realistic lab-scan imperfections where appropriate.
- Setting layer: depict {배경} as a believable environment from the selected era, including tactile surfaces like wallpaper, brick, wood grain, vinyl flooring, curtain fabric, old posters, café menus, street pavement, or household objects when they fit the source.
- Color layer: grade according to {컬러 톤}, keeping skin tones coherent and avoiding modern digital saturation.
- Optional photo-memory details: add a tiny timestamp such as “1998.05.01”, “서울”, or “봄 오후” only if it feels like a real film-camera imprint or album annotation; keep it small, imperfect, and peripheral.
- Final finish: output a square 1024x1024 vintage film i2i result with preserved identity, period authenticity, layered analog texture, and a lived-in photographic mood.

[Style Rules]
- Typography: no headline typography; only tiny authentic photo artifacts are allowed, such as an orange camera timestamp, film-lab scan number, or a small album-note style mark. If Korean appears, render it accurately, e.g. “서울”, “봄 오후”, or “추억”.
- Color palette: derive from {컬러 톤}; favor era-specific muted amber, faded cyan, soft yellow, washed sepia, oxidized green, warm indoor tungsten, or gentle pastel shifts rather than modern vivid colors.
- Film border/shadow: allow realistic film-scan edge darkening, light leaks, corner fading, soft vignette, uneven exposure, or a subtle printed-photo edge if it suits {필름 결}.
- Detail density: include natural environmental texture and era-specific background cues while keeping the subject visually dominant and recognizable.

[Visual Style]
- Camera / lens: 35mm film snapshot look, 50mm f/2.0 or compact point-and-shoot equivalent, with mild focus softness and realistic analog grain.
- Lighting: preserve the reference lighting style as closely as possible; if rebuilding, use soft ambient room light, window daylight, tungsten practical lamps, or overcast street light with gentle contrast and period-realistic highlight bloom.
- Color grade: period-authentic vintage grading matched to {시대 결}, with filmic blacks, softened highlights, uneven color response, subtle shadow tint, and the palette direction from {컬러 톤}.
- Material realism: keep fabric weave, hair strands, skin texture, glass reflections, wall texture, paper aging, and dust visible enough to feel like a real scanned photograph.

[Mood]
Authentic analog portrait conversion — like a well-preserved family album scan, a 35mm street snapshot from a vintage photography archive, or a rediscovered personal photo with real atmosphere and tactile film history.

[Critical]
- Korean text accuracy: if any tiny date/location/album mark is rendered, it must be legible Korean or numeric text such as “서울”, “봄 오후”, “추억”, or “1998.05.01”; do not add large captions.
- Preserve the exact subject identity from {참고 이미지}; do not alter facial structure, age, gender expression, or recognizable features.
- Keep the original composition framing and subject placement as closely as possible while changing only the film-era styling and surrounding analog atmosphere.
- Maintain believable vintage texture: grain, slight color fade, dust, small scratches, halation, and analog imperfections are encouraged; AI-smooth skin is not.
- Match {비율} as a square social portrait result while preserving the 1024x1024 output size implication.
