定影液, 固定剂
a solution used in traditional film photography to remove any remaining light-sensitive silver halide crystals from a photographic emulsion, effectively "fixing" the image on the film or paper and making it permanent
A fixer is a chemical solution used in photographic processing to make images permanent and light-resistant. After a photograph is developed, the fixer dissolves any remaining light-sensitive materials that were not exposed to light, stopping the development process. This ensures that the image will not change or fade when exposed to light in the future. The fixer is a crucial step in both film and paper development, solidifying the image so it can be safely viewed in normal lighting conditions.
