Abstract
A photographic silver bromide emulsion is presented containing twinned grains completely uniform in grain habit and size. The special crysta l type occurring in this emulsion is described and explained. [AgX(n)] (n-1)- complex ions are not involved in the formation of the twinned c rystals. The influence of twin planes on photographic properties is st udied by comparing the twinned grain emulsion with an emulsion contain ing regular cubic grains. It is found that crystal lattice defects int roduced by twin planes enhance the efficiency of latent image formatio n.
