没想老照片能修复得这么清晰
可惜奈何原图太不清晰，最高的虽然是80%，但是普遍在60%

修改了一版提示词：
[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
