旧照片修复为单反肖像

Using the provided reference image, restore the damaged old family photo into a natural-looking modern high-resolution portrait while keeping the same 4 people, pose, framing, clothing, and outdoor rural setting unchanged. Remove all visible age damage including tears, cracks, creases, stains, worn paper edges, scratches, and fading. Convert the black-and-white sepia image into realistic soft color, preserving accurate skin tones and neutral earth-toned clothing. Enhance fine detail, sharpen fabric and hair texture, improve contrast and dynamic range, and upscale it to professional DSLR-quality realism with clean focus and a subtle shallow depth of field, as if photographed on a Canon EOS R6 II. Keep the result highly realistic, natural, and faithful to the original faces and proportions.
