ABSTRACT
The response to pre- and post-exposure pressure of a model halide exchange emulsion with a highly disordered grain structure is described. Variations in the response to pressure with changes in surface chemical sensitization and exposure time have been investigated for both surface and internal development. It is shown that the results cannot be interpreted entirely in terms of the classical surface/internal competition mechanism. It is proposed that account must be taken of the effects of pressure on silver halide emulsion grains in terms of the generation of free holes and electrons.
