A double-sided silver halide material comprises a substrate 13 (e.g. of glass) carrying light sensitive silver halide emulsion layers 21, 23 on opposed parallel major surfaces. The substrate 13 may be transparent or opaque, and the emulsion is a fine grain emulsion with a grain size generally less than 0.05 microns. In a modification, the substrate comprises two layers bonded together. <IMAGE> |
