Restore old pictures to 4k

Restore this old photograph with extreme realism and maximum fidelity in true 4K resolution. Preserve the original aspect ratio of the image exactly as provided — do not crop, stretch, or reframe the scene in any way. This image may contain one or more people. Treat each person individually and with equal priority. Preserve the unique physical identity of every subject with absolute accuracy, including facial structure, proportions, age, expression, gaze, skin tone, and all distinguishing characteristics. Do not alter, beautify, stylize, reshape, or modify any face. Do not merge, blend, or average the features of different people. Reveal ultra-fine details for every person in the image: visible skin pores, wrinkles, expression lines, sun marks, freckles, texture irregularities, natural imperfections, realistic shadows, skin micro-contrast, individual hair strands, eyebrows, eyelashes, lips, and beard stubble where present. Maintain high sharpness on every face without oversmoothing or plastic skin effect. Keep all visible body parts, clothing, fabric texture, and natural folds intact for each subject. Preserve spatial relationships between people — do not alter positioning, distance, or relative proportions between individuals. Restore the full background and environment with authentic texture and depth. Do not blur, replace, invent, or distort any part of the scene. Maintain readable environmental details with realistic depth. Apply uniform, balanced sharpness across the entire image — foreground, subjects, and background — with no selective blur or cinematic depth of field effect. Every person and element must be equally sharp and well-defined. Restore lighting faithfully across the whole scene, respecting the original light direction, shadows, contrast, and atmosphere for all subjects simultaneously. Correct exposure and color balance naturally. Remove scratches, dust, stains, noise, blur, fading, and film damage without losing texture or detail. If the photograph is black and white, sepia, faded, or shows any signs of age-related color loss, apply full and natural colorization to the entire image. Infer realistic, historically accurate colors based on visual context, skin tones, clothing, environment, and era. Make colors vivid, rich, and lifelike — not desaturated, not faded, not muted. Skin tones must look warm and natural. Clothing, hair, eyes, and background elements must receive accurate, believable colors consistent with the scene. Do not leave any part of the image uncolorized. The final result must look like a naturally colorful photograph taken in high definition, never like a colorized or filtered image. No warping, no stretching, no perspective distortion, no AI artifacts, no face hallucination, no invented features. Ultra-realistic photo restoration, full scene preservation, extreme detail on every subject, natural skin tones, true-to-life colors, high fidelity, ultra-detailed, 4K.
