FIELD: photographic industry. SUBSTANCE: silver bromide/iodide photographic emulsions suitable for negative panchromatic photographic materials are sensitized by introducing into molten emulsion at 40-45 C spectral sensitizer with formula I, emulsion being supplemented with sensitizer defined by formula II 10-15 min before sensitizer I is added and sensitizer II to sensitizer I ratio being (2-3):1. EFFECT: improved photosensitivity. 1 dwg, 1 tbl
