Zusammenfassung:	PROBLEM TO BE SOLVED: To make obtainable a high contrast emulsion which ensures a picture contrasty and having a sharp toe and good stability of sensitivity every lot by incorporating rhodium ions into a solution containing halogen ions and carrying out mixing at below a specified pH of the solution. SOLUTION: In a double jet mixing method in which a solution containing halogen ions and a solution containing silver ions are simultaneously mixed, rhodium ions are incorporated into the solution containing halogen ions and mixing is carried out at
