So I've just started the process of rolling a 120 film onto a plastic reel tonight when my all too regular thought of; 'is it dark enough in here' starts to set in'. Of course it is, as it has been for the countless rolls of film before this one. Difference tonight is the old, squeaky reel I'm using is misbehaving and generating a static spark of light as it recieves the film......annoying! After scouring the room (which has become a storage/dumping facility for family in my absence) for a good 15 minutes I finally have a new spool and can develop the film. Four frames were fogged quite badly. Has anyone had a similar experience and/or do people take precautions to prevent this from happening?
