Abstract
The invention relates to a method and a device for preparing a photographic emulsion. In the device of an external loop type of the invention, a solution of a first halide salt X.sub.1.sup.- is introduced at a point in the loop situated outside the reaction zone R within which the silver salt (Ag.sup.+) added to the loop precipitates almost entirely in order to produce silver halide grains or cause them to grow in said solution, the Ag.sup.+ solution being introduced into the reactor in the form of a 'centered' jet within said reactor, the Reynolds number Re at the point of introduction of the Ag.sup.+ salt being between approximately 5000 and approximately 50,000.
