扮演一名专业照片修复专家。你的任务是对一张退化的老照片进行高精度、保守的修复与历史性上色。最终图像应看起来像一张保存完好的原始冲印照片。

图像分析与修复:

  1. 表面修复:

    • 以数字方式去除深层划痕、灰尘、指纹和湿渍。
    • 重建边缘缺失区域或撕裂处,同时保留相纸的纹理。
  2. 结构保真:

    • 校正几何畸变。
    • 恢复原始对比度,不过曝高光,也不过度压暗阴影。
  3. 面部清晰度:

    • 以极高精度恢复面部特征。
    • 避免「蜡质皮肤」效果;保留自然颗粒与原始微表情。

色彩与美学风格:

  1. 历史色彩调色板:

    • 应用受 1940 年代 Kodachrome 工艺启发的写实上色。
    • 使用柔和、温暖且低饱和的色调。
  2. 肤色:

    • 自然呈现肤色,并考虑当时的环境光照。
    • 避免统一的数字饱和度。
  3. 真实颗粒:

    • 保留 35mm 模拟胶片典型的细腻、有机摄影颗粒。

负面提示词 / 应避免的内容:

  • 不要应用 Instagram 等现代滤镜。
  • 避免「平滑」或「塑料皮肤」效果。
  • 不要使用霓虹色、过度饱和度或锐化伪影(例如白色光晕)。
  • 防止出现数字绘画或 3D 插画的外观。

最终输出质量:

  • 实现照片级写实、博物馆级品质的成品,具备超精细细节(8k 分辨率风格)和绝对的历史保真度。

English original

Act as a professional photo restoration expert. You are tasked with performing a high-precision conservative restoration and historical colorization of a degraded vintage photograph. The final image should resemble a perfectly preserved original print.

IMAGE ANALYSIS & RESTORATION:

  1. Surface Repair:

    • Digitally remove deep scratches, dust, fingerprints, and moisture stains.
    • Reconstruct missing areas or tears at the edges while preserving the texture of the photographic paper.
  2. Structural Fidelity:

    • Correct geometric distortion.
    • Restore the original contrast without overexposing highlights or excessively darkening shadows.
  3. Facial Clarity:

    • Recover facial features with extreme precision.
    • Avoid the "wax skin" effect; maintain the natural grain and original micro-expressions.

CHROMATIC & AESTHETIC STYLE:

  1. Historical Color Palette:

    • Apply a realistic colorization inspired by the Kodachrome process of the 1940s.
    • Use soft, warm, and desaturated tones.
  2. Skin Tones:

    • Render skin tones naturally, considering the period's ambient lighting.
    • Avoid uniform digital saturation.
  3. Authentic Grain:

    • Preserve a fine, organic photographic grain typical of 35mm analog film.

NEGATIVE PROMPT / WHAT TO AVOID:

  • Do not apply modern filters such as Instagram.
  • Avoid "smooth" or "plastic skin" effects.
  • Refrain from using neon colors, excessive saturation, or sharpening artifacts (e.g., white halos).
  • Prevent the appearance of a digital painting or 3D illustration.

FINAL OUTPUT QUALITY:

  • Achieve a photorealistic, museum-quality finish with ultra-defined detail (8k resolution style) and absolute historical fidelity.
