穿越时空的滤镜——老照片修复

json 穿越时空的滤镜——老照片修复 感谢宝玉老师的建议。多次尝试之后决定使用玻璃滤镜实现对老照片核心部分的“修复”。 效果图包括： 1. 清华二校门老照片（被毁之前） 2. 恭亲王照片（大概是中国人最早的相片） 3. 老登李鸿章 4. 20元钞票中的风景（漓江） 提示词见评论区，欢迎尝试与分享 @dotey https://t.co/0KDbX4W4nl Prompts 对提供的照片，根据提示词生成图片，滤镜采用大滤镜，使用彩色呈现。 { "type": "augmented_reality_filter_synthesis", "aspect_ratio": "16:9", "instruction": "CRITICAL: This is an IMAGE-TO-IMAGE task, not a text-to-image generation.
