As I mentioned before, you squeeze the edges of the film together slightly. This takes the film out of the track and then you can rotate the reel the opposite way and the film comes off the reel. Squeezing the film together lets you get by the film guides/ball bearings as you rotate the reel. You can do this when you want to take the film off the reel when you're having trouble loading it and want to start over. After the film has been developed, this is usually not necessary as the film will easily slip out. Photo-Flo is a pretty good lubricant.
