i had a lot of Polaroid 669 film in two of my land cameras.
i attempted to use them up before they were goners but it appears i was too late. light leak anyone? the film was ruined.
except i dropped one on my heater, because i am clumsy and when i ripped about the film i found my hand print! exciting.
i dinked around putting the film on the heater and drawing over it.
I got an interesting effect but stopped after the heart in fear I would come up with a brilliant idea later and not have any film left.
All is not lost.
