Abstract

AbstractIntroduction of iodide in AgBr emulsion grains results in several effects. One of them, a change of size distribution, can be prevented by preparing emulsions different in iodide content but equal in grain size and with a narrow size distribution. It is demonstrated that the number of photoelectrons captured in the mass of mixed crystals, prepared by introducing iodide at initial precipitation, is strongly increasing with increasing volume of the grains. The probability of surface latent image formation is asymptotically approaching zero with increasing I/Br ratio.It is assumed that the size and the composition of an iodide-containing core determine the internal latent image formation in these grains.
