Daylight Spool definition

A spool made of aluminum that holds 100 feet of film footage.  The spool is painted black and features opaque solid sides that are necessary to guard the film from exposure when the camera is loaded in daylight.  The term comes from the idea that the film has the ability to be loaded inside the camera without the use of complete darkness (to keep the film from being exposed obviously).  There are 400 foot daylight spools as well; however, they are not often utilized because they are not very compatible with a magazine.
