Lippmann photographs can, in principle, reproduce the entire incident spectrum at every point in the recording.
This paper presents a comprehensive model of the Lippmann process, including exposure, chemical processing
and subsequent reproduction. The main emphasis is on the optical properties of emulsions, where the theory of
radiative transfer is used to obtain a detailed description of how interference patterns are formed in the presence
of scattering particles and absorption. The results presented illustrate the reproduction fidelity of Lippmann
photographs and highlight the most significant factors influencing their quality. Whereas the reproduction of
monochrome sources is excellent, locally broadband signals are more problematic. Several practical measures to
improve upon broadband performance are discussed.
