The photographic emulsions then in use were insensitive to most of the spectrum, so the result was very imperfect and the demonstration was soon forgotten.
During the 1880s the collodion process, in turn, was largely replaced by gelatin dry plates -- glass plates with a photographic emulsion of silver halides suspended in gelatin.
In a film camera that uses the gelatin-silver process, light falling upon photographic emulsions containing silver halides is recorded as a latent image.
Extremely fine-grained high-resolution photographic emulsions are inherently much less light-sensitive than ordinary emulsions, so long exposure times were required.
The photographic emulsion used for color photographic materials consists of three color emulsion layers (cyan, yellow, and magenta) along with other supporting layers.
The light passed through the supporting glass sheet into a very thin and nearly transparent photographic emulsion containing submicroscopically small silver halide grains.
