[Frameworks] spools, reels and rolls

[mstarkmcr at gmail.com]

Is there a difference in standard measurements of lengths of film on spools, reels and rolls?

A roll of film is for shorter lengths while a reel is for longer ones? for example, 100 foot roll and 1000 foot reel

Can you say a spool of film - or have i confused things? Are these terms different for super 8, 16 and 35mm?

Any help in untangling and defining this will be much appreciated!
