Potassium iodide (chemical formula: KI) is a white, water-soluble salt composed of potassium and iodide ions. It is commonly used in medicine, chemistry, and photography due to its reactivity and stability.

In photography, potassium iodide is used during the preparation of silver halide emulsions—especially in older or alternative photographic processes. When added in small amounts, it helps control the size and sensitivity of silver halide crystals, improving image quality and consistency.

Potassium iodide can also act as a restrainer in some developers, helping to reduce fog and increase image contrast. While less commonly used in modern photographic chemistry, it played a key role in the early days of film and plate photography for stabilizing emulsions and enhancing tonal precision.
