As the crank of the camera which takes the pictures can be stopped at any moment and the turning renewed only after some complete change has been made on the stage any substitution can be carried out without the public knowing of the break in the events. We see a man walking to the edge of a steep rock, leaving no doubt that it is a real person, and then by a slip he is hurled down into the abyss below. The film does not indicate that at the instant before the fall the camera has been stopped and the actor replaced by a stuffed dummy which begins to tumble when the movement of the film is started again. But not only dummies of the same size can be introduced. A little model brought quite near to the camera may take the place of the large real object at a far distance. We see at first the real big ship and can convince ourselves of its reality by seeing actual men climbing up the rigging. But when it comes to the final shipwreck, the movement of the film is stopped and the camera brought near to a little tank where a miniature model of the ship takes up the role of the original and explodes and really sinks to its two-feet-deep watery grave.
While, through this power to make impossible actions possible, unheard of effects could be reached, all still remained in the outer framework of the stage. The photoplay showed a performance, however rapid or unusual, as it would go on in the outer world. An entirely new perspective was opened when the managers of the film play introduced the “close-up” and similar new methods. As every friend of the film knows, the close-up is a scheme by which a particular part of the picture, perhaps only the face of the hero or his hand or only a ring on his finger, is greatly enlarged and replaces for an instant the whole stage. Even the most wonderful creations, the great historical plays where thousands fill the battlefields or the most fantastic caprices where fairies fly over the stage, could perhaps be performed in a theater, but this close-up leaves all stagecraft behind. Suddenly we see not Booth himself as he seeks to assassinate the president, but only his hand holding the revolver and the play of his excited fingers filling the whole field of vision. We no longer see at his desk the banker who opens the telegram, but the opened telegraphic message itself takes his place on the screen for a few seconds, and we read it over his shoulder.
