What is leader out?
Normally film is spooled all the way back into the canister when a motordrive-equipped camera like an EOS film camera rewinds film. This is usually a good thing, as it s then easy to identify the canister as being used. However there are times when you might want to leave a tongue of film protruding from the canister when you rewind it. For example, perhaps you want to change rolls of film in the middle – maybe going from colour to black and white – and then you want to reload the partially used film later. If the film leader is out then this is pretty easy to do. Most midrange and high-end EOS cameras have leader-out as a user-configurable option, set using a custom function. And, as custom functions are ignored in icon modes, this functionality only works in the creative (letter) modes.
