Restauración de foto vieja — comparativa de prompts

ROLE:
You are an elite image restoration and enhancement engine specializing in photorealistic upscaling.
ABSOLUTE RESTRICTION — IDENTITY PRESERVATION
Preserve 100% of the original image: facial identity (Face 173), expression, pose, body structure, clothing, accessories, background, framing, and overall composition.
Zero alterations. Zero additions. Zero removals.
This requirement is non-negotiable.
PRIMARY TASK — QUALITY ENHANCEMENT ONLY
Transform the uploaded image from its current state into ultra-high-definition cinematic quality, while maintaining perfect pixel-level fidelity to the original content.
ENHANCEMENT OBJECTIVES (in order of priority)
Facial Detail
Recover crisp facial geometry, clear iris definition, natural skin texture with visible pores and subtle micro-imperfections, without smoothing or AI beauty filters.
Hair and Edges
Render individual hair strands with realistic separation and produce clean, refined edges across all subjects.
Skin and Texture
Use only organic, photorealistic textures. Preserve natural skin grain, freckles, moles, and expression lines. Avoid plastic-looking skin or AI-induced smoothing.
Lighting
Apply balanced cinematic lighting with high contrast and excellent depth. Enhance the existing light sources onlywithout introducing any new lighting.
Clarity and Depth
Maximize sharpness throughout the focal plane while preserving the original natural depth of field and bokeh wherever present.
OUTPUT SPECIFICATIONS

* Resolution: Upscale to 8K.
* Quality Standard: ProRes-grade / Studio Master quality.
* Sharpness: Recover the maximum possible detail without introducing artifacts.
* Color: Preserve the original color science while improving only the dynamic range.

STRICT PROHIBITIONS

* No generative fill, inpainting, or content generation.
* No style transfer or artistic reinterpretation.
* No modification of facial features (size, shape, or symmetry correction).
* No background replacement or extension.
* No AI beauty filters or skin smoothing.

VALIDATION REQUIREMENT
The enhanced result must be indistinguishable from the original in terms of content, differing only in technical image quality.

TASK
Photo restoration. Input: an old, degraded photograph. Output: the exact same photograph in modern high-resolution quality. Restoration only — never reimagination.

IDENTITY LOCK (highest priority — overrides everything below)
Preserve exactly: facial identity, face shape and proportions, expression, gaze, pose, body structure, clothing, accessories, background, framing and composition. Zero additions, zero removals. Do not beautify, slim, de-age, or symmetry-correct any face.

RESTORATION OBJECTIVES (in priority order)
1. Face: recover sharp facial geometry and clear iris definition; natural skin texture with visible pores, expression lines and subtle micro-imperfections. No skin smoothing, no beauty filters.
2. Hair and edges: individual hair strands with realistic separation; clean, refined edges on all subjects.
3. Damage repair: remove noise, dust, scratches, stains and compression artifacts — including the yellow horizontal streaks across the print and the green marker stroke at the lower left (scan damage, not photo content). Rebuild damaged spots using only what is consistent with their immediate surroundings — never invent new objects or content.
4. Lighting and color: keep the original light sources and direction; enhance only clarity and dynamic range. Do not introduce new lighting. The photograph is black-and-white: remove the yellow age cast and restore clean, neutral monochrome tonality. Do not colorize.
5. Sharpness and depth: maximize detail only within the original focal plane; keep out-of-focus areas exactly as blurred as they are. No oversharpening halos or artifacts.

PROHIBITED
Style transfer or artistic reinterpretation · new lighting · colorization · background replacement or extension · any change to facial features (size, shape, symmetry) · AI-smoothed skin.

SUCCESS CRITERION
Side by side with the original, a viewer must recognize the exact same photo — same people, same moment, same crop — differing only in technical quality, as if captured today on a professional camera.

TASK
Photo restoration with colorization. Input: an old, degraded black-and-white photograph. Output: the exact same photograph, restored to modern high-resolution quality AND rendered in natural, believable color. Restoration plus faithful colorization — never reimagination.

IDENTITY LOCK (highest priority — overrides everything below)
Preserve exactly: facial identity, face shape and proportions, expression, gaze, pose, body structure, clothing, accessories, background, framing and composition. Zero additions, zero removals. Do not beautify, slim, de-age, or symmetry-correct any face.

Rebuild damaged spots using only what is consistent with their immediate surroundings — never invent new objects or content.
4. COLORIZATION: convert the monochrome image to full natural color with historically plausible, restrained tones — warm medium skin tones appropriate to the couple, dark brown-black hair, white bridal dress and veil, white/cream men's shirt, white and cream flowers with deep green ferns and foliage, dark green background vegetation, warm white string lights. Even, believable saturation like a professionally colorized archival photo — no sepia wash, no hand-tinted look, no oversaturated or fantasy colors.
5. Lighting: keep the original light sources and direction; enhance only clarity and dynamic range. Do not introduce new lighting.
6. Sharpness and depth: maximize detail only within the original focal plane; keep out-of-focus areas exactly as blurred as they are. No oversharpening halos or artifacts.

PROHIBITED
Style transfer or artistic reinterpretation · new lighting · background replacement or extension · any change to facial features (size, shape, symmetry) · AI-smoothed skin · oversaturated or unrealistic colors.

SUCCESS CRITERION
Side by side with the original, a viewer must recognize the exact same photo — same people, same moment, same crop — now in natural lifelike color, as if the moment had been captured today on a professional color camera.
