What is clearing?

Explanation:
Clearing is the step in film processing where the unexposed silver halide crystals are removed from the emulsion by the fixer. After development, the exposed areas have been converted to metallic silver to form the image, while unexposed crystals remain. The clearing step dissolves and washes away those unexposed crystals, making the film transparent and stable for viewing. This is distinct from drying, adding more unexposed crystals, or hardening the emulsion, which are different processing concepts.
