Film base: Difference between revisions

'''Nitrate''' base is the infamously unstable and flammable stock that most release prints were made of until the early 1950s. Discontinued in 1951 and replaced with acetate "safety film". Look for the word "nitrate" written along the edge of the film, though make sure it's not printed in from the original negative, as many nitrate prints were later re-struck on acetate or polyester stock. You want to look for black text, text printed in from the negative will appear white. Be '''very careful''' when handling a film print you suspect may be of nitrate stock. It's considered a hazardous material and becomes more dangerous as it deteriorates. Make sure you know the proper storage specifications for nitrate if you have any!
