Film Restoration & Preservation Hub
Welcome to the definitive, open-access knowledge base for technical film conservation, photochemical repair, and optical liquid wet gate scanning. Grounded in verified chemical standards and optical physics.
Wet Gate Printing (Liquid Gate)
Wet gate technology represents the pinnacle of physical scratch mitigation. By submerging film in a liquid with a refractive index precisely matching the cellulose triacetate base (approx. 1.490), light refracts evenly, rendering deep handling scratches optically invisible at capture time without losing original grain or details.
