Промт для исторической колоризации портретов и старых фотографий

HISTORICALLY ACCURATE PHOTO COLORIZATION.
Task: Add natural, era-appropriate colors to a black-and-white or sepia photograph.
HARD CONSTRAINTS: IDENTITY LOCK (preserve all faces and people exactly), NO STRUCTURAL CHANGES, NO RECONSTRUCTION of missing areas.
COLORIZATION: Add natural chroma over the clean restored image. Preserve restored luminance, fabric weave, buttonholes, pores, moles, eyes, hair, and all real small details. Do NOT reintroduce cracks, paper texture, stains, or sepia wash as "style". Historically plausible but natural, moderate saturation. No vivid digital colors.


NO FACE RECONSTRUCTION:
- Do NOT reconstruct faces
- Do NOT guess missing features
- Clean non-facial damage around the face, but leave truly missing facial features ambiguous
- Keep identity exactly as visible


SUBJECT: No people — objects, buildings, landscapes, or documents.
- Focus restoration on structural details, textures, and readable content.
- Preserve any visible text, inscriptions, architectural details exactly.
- Do NOT add decorative elements or fill with invented content.
- For documents: preserve all text and graphic elements with maximum legibility.


SOURCE: Low-quality or dirty scanner output.
- Apply careful noise reduction while preserving genuine photographic detail.
- Remove scanner artifacts (lines, dust, haze) but preserve original photograph texture.
- Edge clarity may need gentle enhancement but avoid over-sharpening.
- Distinguish between scanner dirt and genuine photograph damage.


ERA: Modern (post-2000, digital era).
- Colorization palette: natural, accurate digital-photography colors.
- Skin tones: accurate, neutral, as would appear in modern photography.
- If this is a modern photo that appears black-and-white, it was likely intentional — colorize naturally.
- No vintage aesthetics — accurate contemporary colors.


ANTI-HALLUCINATION (ABSOLUTE):
- Do NOT invent faces, people, or anatomy
- Do NOT replace identity under any circumstance
- If a region is missing or unreadable — leave it incomplete rather than guess
- Do NOT extend the canvas or fill outside original photo edges
- Do NOT add elements not present in the source


TEXT AND INSCRIPTION PRESERVATION:
- Preserve ALL visible text, dates, signatures, captions, studio stamps on the photograph.
- Do NOT remove, obscure, or modify any written elements — they are historical artifacts.
- This includes: border captions, handwritten notes, photographer studio marks, dates, names.
- If text is damaged and partially readable — clean what is readable, leave damaged parts as-is.
- Do NOT attempt to complete or invent missing characters in damaged text.


MUTED COLORIZATION (BASE RULES):
- Historically accurate, low-to-moderate saturation palette
- Skin tones: neutral beige or pink-beige, slightly cool, low chroma — NEVER red, orange, warm-orange, or terracotta
- No vivid digital colors, no modern grading or HDR-like saturation
- Slightly faded analog-film look when in doubt
- Color consistency: same object must have same color throughout the image


COLORIZATION DETAIL LOCK:
- Treat the input as a clean restored master, not as a hand-coloring canvas.
- Preserve every real buttonhole, seam, fabric weave, mole, eyelid, iris shape, and hair strand.
- Do NOT preserve or emphasize damage artifacts: cracks, tears, fold lines, paper stains, mold, scanner haze, and scratch edges should stay cleaned if the restore pass removed them.
- Do NOT repaint the face; do NOT replace eye color with bright blue or cyan. Eyes should be low-saturation brown, hazel, grey, or muted blue only when strongly plausible.
- Do NOT make skin blue, cyan, purple, orange, red, terracotta, or plastic. Skin must stay neutral beige/pink-beige with low chroma and visible natural texture.
- Dark jackets, suits, coats, and uniforms must be one consistent muted charcoal/navy/blue-grey fabric color. Do NOT create yellow, brown, green, blue, or rainbow mottled color spots on dark clothing.
- Era context is only a color hint; never let era styling override the actual photo content or make the result look hand-painted.
- If unsure about an object's color, choose a restrained neutral tone and preserve its luminance/detail.


REFERENCE CONTEXT (do not interpret, do not extend):
- Subjects: 0
- Faces: clear, missing
- Damage level: medium
