Loading the Camera
Learn how to load and to unload, first without unrolling your film.
Afterward adjust the roll in the camera and see that it is properly
placed and will turn easily, before you loosen the end of the film. If
you detach the gummed paper which keeps the film tightly wrapped before
placing the roll in the camera, the whole film will spring loose from
its spool and become light-struck before you can adjust it.
