Specification

Application

Silver iodide is a yellow powder formed by the combination of a soluble iodide combined with silver nitrate. Silver iodide could also be formed by exposing metallic silver to the fumes of bromine as in the daguerreotype process. This was the primary halide used for all of the 19th century camera processes until the introduction of the silver bromide gelatin plate. With the exception of the daguerreotype, all silver iodide processes relied on physical development using a reducing agent such as gallic acid, pyrogallic acid, or ferrous sulfate, an acid restrainer, and excess silver.
