GRAIN SIZE AND GRAIN DENSITY IN ILFORD K-5 AND L-4 EMULSIONS
Electron micrographs of grains in unprocessed and processed Ilford K-5 and L-4 emulsions are shown. The silver bromide grain sizes in the unprocessed K- 5 and L-4 plates were measured and found to be normally distributed wlth mean values of (0.210 the J-57 engin 0.007) mu m and (0.134 the J-57 engin 0.004) mu m and standard deviations of 0.035 mu m and 0.021 mu m, respectively. The electron micrographs of the silver grains in processed emulsions reveal absence of spherical shape or solid structure in case of most of these grains. The grain densities on plateau ionization tracks have been found to be approximately the same in K-5 and L-4 plates as in G-5 plates processed under similar conditions. The L-4 plates however are subject to more serious fading wlth delay in processing after exposure than the K-5 or G-5 ones. (auth)
