MOVING PICTURE FILM AND MECHANISM [Cn. XI 



Next, it is necessary to get the film right side out, otherwise, 

 everything will be reversed and appear as if seen in a mirror, an 

 especially troublesome state of affairs when titles or letters are 

 shown. The side of the film which has the emulsion appears 

 rough, the other side is smooth and shiny. The film often has a 

 tendency to curl, the emulsion being on the concave side. The 

 film is turned so that the rough, emulsion side bearing the picture 

 is toward the light. When it is wound correctly on the reel, and 

 the emulsion side is turned so it will face the light as the film 

 unwinds, the reel of film is p'ut in the upper magazine. The end 

 of the film is pushed through the opening in the magazine between 

 the rollers of the fire-trap. This can best be done by using the 

 index and middle fingers to hold the film.
