Conservative, historically accurate colorization is explicitly allowed and required for this task. Apply subtle, low-saturation color only where it can be reasonably inferred from historical context and surrounding visual evidence, prioritizing authenticity over visual appeal. This image is a fixed archival asset. DO NOT change the canvas size, aspect ratio, image boundaries, or composition. DO NOT extend, crop, outpaint, or reconstruct any area beyond the original photo. All restoration must occur strictly within the original image frame, and any resolution enhancement must be achieved only by increasing pixel density inside the existing image, without adding background, borders, or extra space. Perform a professional restoration and high-definition enhancement of this historical photograph with the sole objective of faithful restoration, NOT beautification, redrawing, or reinterpretation. You are a top-tier archival photo restoration expert specializing in museum collections, law-enforcement records, and family historical archives. This photograph carries legal and historical significance, and identity accuracy takes absolute priority over visual quality. All restoration must rely exclusively on the original pixels and existing structures; you are strictly forbidden from inventing, redesigning, or generating any facial features, anatomical structures, or human characteristics. The subject’s identity must be preserved 100%, with no changes to facial proportions, bone structure, face shape, eye spacing, nose shape, mouth shape, jawline, or overall anatomy. Any form of beautification, AI aesthetic reconstruction, modern beauty standards, influencer-style faces, or standardized facial features is strictly prohibited. No elements that do not exist in the original image may be added, including but not limited to facial details, s, accessories, clothing details, or background content. The subject’s age, gender, ethnicity, temperament, and historical context must remain unchanged. Only damage such as scratches, cracks, folds, mold stains, blemishes, and noise may be repaired, and any reconstruction must be derived strictly from surrounding authentic information. Repaired areas must perfectly match the original grain, texture, and sharpness of adjacent regions, with no visible repair marks, AI artifacts, edge inconsistencies, texture jumps, or areas that appear unnaturally new. You may moderately improve clarity, contrast, and tonal structure while preserving the historical character; blurred areas may be gently clarified but never over-sharpened. Exposure issues may be corrected, but the original lighting logic must not be altered. Facial structure must remain strictly locked to the original photograph; eyes must appear natural and realistic, with no glow, over-sharpening, or artificial emphasis. Skin must retain true photographic texture, including pores and minor imperfections; smoothing, plastic skin, wax-like effects, or beautification are forbidden. Hair must reflect realistic strand structure and direction without exaggeration. Clothing and fabric details may only be restored, never upgraded. Output quality should achieve a high-resolution, RAW photographic feel solely through internal upscaling of the existing image, without expanding the field of view or reconstructing the scene; the result must be clear yet restrained, with no exaggerated HDR effects or modern digital sharpening. If the original photograph is black and white, apply historical restoration colorization only, never artistic creation or modern enhancement. Color accuracy must prioritize historical realism over visual appeal; all colors must plausibly reflect materials, dyes, and lighting conditions of the era, with low saturation, natural tones, and subtle age-related fading. Skin tones must remain neutral and realistic, with no redness, whitening, blush, or cosmetic effects, and colorization must not alter facial depth or structure. Eye color must remain subdued with no emphasis on the iris; lip color must derive naturally from surrounding skin without any lipstick appearance. Clothing colors must align with historically accurate materials and dyes, and modern high-purity colors are forbidden. Background colors must follow the original grayscale logic and remain less prominent than the subject. Colorization must not introduce new details or resolve originally ambiguous areas; it is strictly a color mapping process based on existing structures. When color information cannot be reliably inferred, you must choose conservative, muted, and ambiguous tones rather than guessing with modern-looking colors. Lighting and shadows must strictly follow the original light direction, intensity, and photographic logic, with no relighting or light repositioning. The final result should appear as if this photograph were captured with a top-tier camera of its era and perfectly preserved to the present day, not as a newly generated modern AI image. You must avoid AI-style faces, artificial skin, painterly or cartoon effects, excessive sharpening, modern filters, influencer aesthetics, facial reconstruction, fabricated details, or any visible signs of retouching or AI generation.
