Abstract: A process for forming a direct positive image by developing, after imagewise exposure to an internal latent image type light-sensitive silver halide photographic material, with a surface developer for silver halide, which process comprises incorporating at least one fogging agent selected from hydrazine compounds, N-substituted cycloammonium salts and benzimidazole derivatives in combination with an amineborane compound into said light-sensitive silver halide photographic material, said surface developer and/or a treating bath used prior to the treatment by said surface developer.

Abstract: An improved method for adjusting bromide ion concentration in a photographic processing solution is disclosed in which the processing solution is contacted with particles of an insoluble bismuth compound.

Abstract: An improved silver halide photosensitive material of the lith-type is disclosed which is suitable for an infectious development in order to obtain high contrast images with high sensitivity. A method for developing the material is also disclosed. The material comprises silver halide grains containing at least 50 mole per cent of silver chloride, less than 40 mole per cent of silver bromide and less than 5 mole percent of silver iodide based on total silver halide, the average size of the grains being 0.05 to 0.5 microns in diameter. The material further comprises a compound represented by the following general formula I or II ##STR1## wherein R is alkyl, aryl, aralkyl or acyl; R' is hydrogen or --OR; and R" is hydrogen or acyl.
