Character featuring Traveling Filter - Glass

Time-Traveling Filter — Old Photo Restoration Thanks to Teacher Baoyu's suggestion. After multiple attempts, I decided to use a glass filter to achieve the "restoration" of the core parts of old photos. Effect images include: 1. Old photo of Tsinghua's Second School Gate (before it was destroyed) 2. Photo of Prince Gong (probably the earliest photograph of a Chinese person) 3. Old-timer Li Hongzhang 4. Landscape from the 20-yuan bill (Li River) Prompts can be found in the comments section, feel free to try and share @dotey
