ACETATE FILM STOCK [Film Technology]






ACETATE FILM STOCK 
[Film Technology]

Film base by acetate. Below freezing point acetate film stock dries out & becomes progressively brittle and subject to static which on the screen, looks like flashes of lightning streaking across the picture area. Film loading a camera without breaking the film becomes difficult. Below -400 F the speed of the film begins to drop and between  -500 F or -600 F a whole extra stop should be allowed. At these temperatures estar or mylar base film is preferable to acetate stock.
