[Purpose]
Korean portrait studio style conversion for i2i, preserving the original person while transforming the image into a formal Korean photo studio finish. Vertical 2:3 editorial studio portrait, identity-safe retouching, suitable for family, graduation, wedding, profile, or milestone commemorative photos with a believable printed-studio atmosphere.

[Composition]
- Preserve the original subject's face and identity exactly, while converting only the styling, background, pose feel, wardrobe, and studio rendering into a classic Korean photo studio look.
- The subject should remain the clear hero, occupying about 65% of the frame height, with refined headroom and shoulders framed cleanly for a premium studio-portrait crop.
- Background treatment: seamless studio paper or painted canvas in {배경 톤}, evenly lit with a natural tonal gradient, subtle paper grain, gentle floor/backdrop transition if visible, and realistic contact shadow behind the subject.
- Composition should feel like a real Korean portrait studio session: centered or slightly off-center depending on {포즈}, with tasteful studio details such as a small posing stool edge, soft reflector catchlight, folded fabric texture, or a faint studio floor line only when naturally fitting the pose.
- Add a subtle printed-photo presentation: a narrow lower margin or small studio proof label may appear with clean Korean text such as "기념사진 · 2026.05", "서울 사진관", or "소중한 오늘", placed small enough to feel like a studio print detail rather than a poster.
- Use {원본 보존} as the identity constraint, {사진관 모드} as the portrait styling direction, {의상} for wardrobe matching, and {카메라·렌즈} for the capture look.

[Core Structure]
- Hero subject area (middle 60%): keep the original person fully recognizable, with natural pores, fine hair detail, real facial asymmetry, and studio-grade retouching limited to tonal cleanup, lint removal, and gentle complexion balancing.
- Face and expression: maintain the original facial structure and expression stability from {원본 보존}, with a calm formal smile or neutral dignified expression appropriate to {사진관 모드}; keep the gaze believable and eye catchlights consistent with the studio lights.
- Wardrobe styling: apply {의상} precisely according to the selected photo-studio mode, with realistic fabric weave, collar structure, seams, buttons, lapels, cuffs, jewelry or boutonniere details only if appropriate to the mode.
- Pose and hands: follow {포즈}, with anatomically correct hands, relaxed shoulders, natural neck posture, and a composed studio stance; if hands are visible, keep fingers natural, proportionate, and softly posed as a photographer would direct.
- Background plane: render {배경 톤} as a premium studio backdrop with realistic matte surface, soft tonal falloff, faint contact shadows, and gentle separation around hair and shoulders.
- Lighting pass: apply {라이팅} as a controlled studio setup, creating even facial illumination, gentle under-chin softness, clean catchlights, realistic shadow under the jawline, and believable separation between subject, clothing, and backdrop.
- Camera rendering: emulate {카메라·렌즈} with a medium-format studio portrait feel, crisp focus on eyes, natural skin detail, controlled depth, accurate fabric texture, and restrained highlight roll-off.
- Studio print details: if a lower caption strip or proof mark is included, set short Korean text cleanly in small Pretendard-style type, e.g. "2026년 5월 · 가족사진", "STUDIO 기록", or "서울 강남 사진관", with no spelling errors.
- Final grade: keep the image elegant, formal, and print-ready, with balanced contrast, rich but restrained tonal depth, believable photographic paper texture, and a refined Korean portrait studio finish.

[Style Rules]
- Typography: optional small studio-print label only; use Pretendard SemiBold or Pretendard Regular, 20–32px equivalent, accurate Korean typesetting, placed in a lower margin, corner proof label, or tiny studio credit line.
- Color palette: anchor the scene to {배경 톤}, with muted studio neutrals such as cream gray, soft beige, warm taupe, off-white, charcoal accents, and natural skin tones; avoid oversaturation while retaining lifelike depth.
- Border/shadow: if presented as a studio print, allow a thin off-white photo-paper edge, very soft contact shadow, 4px y-offset, 12px blur, 12–15% opacity, and slight paper thickness for a realistic keepsake-photo feel.
- Surface finish: keep the portrait matte and print-like, with subtle photographic paper grain, real textile texture, natural hair detail, and no plastic smoothing, CGI gloss, or synthetic overlay effects.
- Decorative details: allow restrained Korean studio finishing touches such as a small date/location label, embossed-looking studio credit, neutral mat-board edge, or a simple archival sticker reading "보정본" or "기념사진" when it supports the portrait mode.

[Visual Style]
- Camera / lens: emulate Hasselblad H6D-100c, 80mm f/4, ISO 100, studio portrait framing, sharp central detail with smooth edge falloff.
- Lighting: soft studio key light from front-left at about 45°, very light fill from front-right, subtle hair or rim separation when appropriate, realistic reflector softness, minimal shadow contrast, consistent with a formal Korean portrait studio.
- Color grade: neutral cream + beige + soft gray grade with accurate skin tones, low saturation, refined midtone contrast, clean white balance slightly warm but not yellow, and a polished studio-print finish.

[Mood]
Classic Korean portrait studio editorial — formal keepsake photo quality with the restrained dignity of a high-end family studio portrait, enhanced by subtle real-world studio print details, refined wardrobe texture, and believable photographic depth.

[Critical]
- Korean text accuracy: if any caption, proof label, studio credit, or date/location text appears, render it in clean Korean without broken characters; recommended short strings include "기념사진", "2026년 5월", "서울 사진관", "소중한 오늘", or "보정본".
- Identity invariants: the subject's face, age impression, facial proportions, and personal identity must remain 100% recognizable from the reference image.
- Portrait invariants: no extra limbs, no warped hands, no exaggerated beauty retouching, no facial structure changes, no artificial bokeh halos, no CGI look, and no plastic skin smoothing.
- Studio invariants: keep the image consistent with a real Korean photo studio capture, including believable lighting, fabric texture, background contact shadows, clean print finishing, and restrained tonal conversion only.
