[Photo Restoration - Maximum Facial Fidelity]
Source: Vintage sports team group photograph

[CORE PRINCIPLE] This is RESTORATION not RECREATION
- Preserve 100% of original facial features
- Only remove aging artifacts, never alter faces

[FACIAL PRESERVATION - HIGHEST PRIORITY]
MUST preserve exactly:
- Each person's face shape (round/square/long)
- Precise feature positions and proportions (eye spacing, nose bridge height, lip thickness)
- Bone structure (cheekbones, jawline, forehead)
- Original expressions and micro-expressions (smile curves, eye contact)
- Head angles and poses
- Individual unique facial characteristics and identity markers

[ALLOWED RESTORATION] Quality enhancement only:
1. Remove aging artifacts: fading, scratches, dust, creases, yellowing
2. Color restoration: recover uniform blue-white colors, natural skin tones, field colors
3. Clarity upgrade: deblur, denoise, sharpen details
4. Lighting optimization: balance exposure, soften shadows, enhance natural lighting
5. Resolution upgrade: upscale to 4K/8K
6. Skin texture refinement: enhance detail only, don't change original skin characteristics

[FORBIDDEN OPERATIONS]
- Alter facial geometry or structure
- Modify feature shapes or positions
- Apply beautification or stylization
- Add non-existent details
- Change expressions or poses

Output requirements:
- Photorealistic quality
- Maintain 1980s-90s photography atmosphere
- Warm nostalgic color grading
- Natural lighting effect
