WebA simple model is presented that successfully predicts photographic response (characteristic) curves, using only experimental parameters. The model is based on the Gurney-Mott theory of latent image formation. For the first time the details of development, as well as of exposure, are explicitly taken into account.

Webimage was a silver cluster, and Gurney & Mott (I 938) have presented a dynamical theory of the processes occurring. According to this theory, the absorption of light produces electrons and holes in the conduction and valence bands respectively of the silver halide.

Mott it is established that in the direct reduction of silver-bromide emulsions by light (print-out effect), approximately one atom of silver is formed for every quantum absorbed. This only holds for room temperature; at liquid air temperature Berg and Mendelssohn (I937) have shown that the efficiency falls by 105. pryor cattle companyWebOct 10, 2024 · 3.

Shot noise results from the random arrivals of discrete charge; the statistical variation in the arrivals produces shot noise. A space charge develops a potential that slows the carriers down.
