Alchemist In Hollywood

Producer has not verified information recently. Originally produced for motion picture meeting of Southern California section of the American chemical society. "This film was designed to show the chemical work in the motion picture industry. The commentator, with the aid of diagrams, explains the photographic process. Diagrammatic drawings of silver-bromide crystals are shown and we are told of the chemical reaction that occurs when light falls upon them. There are experiments illustrating what occurs when the crystals are given exposures of different intensities and how they receive and store the latent image." "The following sequence deals with the different chemicals used in the developer, and the fixing bath. A comparison is drawn between the 'dark room' operations of a modern equipped laboratory. The film closes showing a positive of the student's grandmother." "'An excellent film on chemistry and physics. Commentary is good and the film is beautifully photographed. May well be used in college and high school classes.'" California
