Latent Image - Stability of Latent Image

Stability of Latent Image

Under normal conditions the latent image, which may be as small as a few atoms of metallic silver on each halide grain, is stable for many months. Subsequent development can then reveal a visible metallic image. (Photographic developers reduce the silver halide grains to silver, but are designed to work preferentially on silver halide crystals with a latent image centers present.

A famous instance of latent-image stability are the pictures taken by Nils Strindberg, the photographer in S. A. Andrée's ill-fated arctic balloon expedition of 1897. The pictures of the expedition and of the balloon stranded on the ice were not discovered and developed until some 33 years later.
