With your camera, you can take multiple exposures on the same negative if you keep the camera from advancing the film. Photographers can create fantastic pictures using this camera trick. Photographers can create pictures of ghosts walking down hallways or have multiple positions of one person kicking a soccer ball.
Great! How do they do it?
If you wanted to make a picture of a ghost walking down a hallway, mount a camera on a tripod and take a half exposure of the hallway. Do not advance the film. Then, without moving the tripod an inch, take another half exposure of someone walking down the hallway. Now you have taken a full exposure of the hallway, but only a half exposure of the person. This is what creates the ghost effect. The exposure for each of the two pictures should be one stop smaller than what would normally be correct. A three exposure picture would require 2 less stops.
If you wanted to catch someone kicking a soccer ball in four different positions, set the exposure to one fourth of the regular exposure. Then snap the picture four times in a row without advancing the film
