Prompt: “Restore the uploaded vintage family photograph while preserving each person’s facial features, age, expression, clothing, and position. Remove dust, scratches, crease marks, and yellow staining without erasing authentic film grain. Recover faded contrast and gently clarify visible details; avoid inventing details in severely damaged areas. Retain the original black-and-white or sepia character, framing, and period atmosphere. Keep skin texture natural, with no modern beautification or artificial sharpening.”
