Enhance this old black-and-white photo to high resolution. Remove excessive grain and noise, sharpen the details, and make the image look like a modern high-quality photograph while preserving the natural look of the people. Faces must remain true to the original without distortion or artificial changes. Do not add or invent any new people, interiors, or background elements. Keep the composition authentic, but improve clarity, contrast, and photorealistic texture details.

Restore and colorize this black-and-white photo with full, vivid, and rich colors. Apply photorealistic saturation and depth across the entire image: skin, clothing, hair, and background. Make the colors bold and lively, similar to analog color photography from the 1980s–1990s, while keeping a natural look. Ensure faces stay true to the original without distortion. Do not invent or add new people, objects, or details — only colorize and enhance what is already in the photo.
