The metal is at least one polyvalent metal selected from the group consisting of Ir, Rh, Pd, Ru, Pt, Os, Fe, Ni and Co. The metal ions are ammonium salt, acetate, nitrate, sulfate, phosphate, hydroxide, or complex salt of the metal. Telluroketones or phosphinetellurides is used as the tellurium compound. It is desirable that the silver halide emulsion is a monodispersed emulsion having a variation coefficient of 22% or less.
