faster film rates

there is some interest in this since 'the Hobbit' has been released in versions that use 48 frames per second and 'Avatar 2' is likely to use an even faster film speed (of 60 fps)
we are used to films at 24 fps - the current standard 

there are opportunities to consider direct and inverse proportion relationships

basically a faster film speed allows the amount of motion blur to be reduced



from Wikipedia - showing how a shutter gate controls the amount of light allowed through to the film (or sensor)
