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.

“Perhaps having built a barricade when you’re sixteen provides you with a sort of safety rail.

—David Hume (1711–1776)
“In history an additional result is commonly produced by human actions beyond that which they aim at and obtain—that which they immediately recognize and desire. They gratify their own interest; but something further is thereby accomplished, latent in the actions in question, though not present to their consciousness, and not included in their design.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
