Restore the input vintage photograph into a sharp, natural, realistically colourised photo, keeping the original content and facial anatomy unchanged. Repair: remove noise, scratches, spots, creases, fading and grain; recover detail and tonal range and balance highlights and shadows; never oversharpen, never produce waxy, plastic or painterly skin. Colour: natural believable skin and material tones, unified grading, no exaggerated stylisation. Keep: facial structure, wrinkles, expression, gaze, head angle, hands and how they hold objects, garment material and folds, background props and depth of field. Output one single finished image with no border, text or watermark.
