What causes exposed silver halide crystals to switch to black metallic silver?
- The designer chemically loosens the energized ionized silver bromide crystals by donating electrons, removing the halides, and precipitating metallic silver in the emulsion layer.
- The negative charge draws positively assessed free silver ions and is reduced to black metallic atoms.
- Guides to the squeeze of the energized, told silver halide crystals into black metallic silver, while the unenergized, unenergized, unexposed silver halide crystals are released from the film.
