A method has been described of chemically sensitizing a silver halide emulsion having silver halide grains and a binder, comprising the steps of adding thereto, besides a chemically sensitizing agent providing sulphur, an organo-tellurium sensitizing compound providing tellurium in a molar ratio amount versus sulphur of less than 0.30. A light-sensitive silver halide photographic element has also been described which has been made highly sensitive by chemically sensitizing a silver halide emulsion which has been made highly sensitive by the method described hereinbefore.
