This paper discusses current knowledge of the behaviour of silver halide materials as recording media for holographic images. The work is structured so as to crystallise the contribution of certain key workers in the field. It is shown that despite early pessimism about the performance capability of the silver halide, experimental achievement is of a high order of finesse with only minor advances to be expected overall in the use of such media to achieve high diffraction efficiency. The approach of Soviet scientists to the problem of image modulation has led to an essential dichotomy of technique between East and West; the 'brown' and 'black' silver technologies. These differences are highlighted and important areas demanding further progress are outlined.
