found, one can be reasonably certain that the film is on safety base regardless of any other markings that the film may show.
IDENTIFYING SAFETY FILM
1 his method of identification of safety film is quite useful and necessary, but it has some limitations. One of them is that the marking does not register on some colored film stock; the other is that in a spliced roll of film it would be impossible to detect any section of nitrate film unless every foot of film were carefully examined. Therefore, Eastman has adopted a second method for identifying new acetate film stock.
That manufacturer is now adding a very small amount of fluorescent chemical to the safety film base. When a roll of film containing any new safety stock is viewed on edge under a suitable ultraviolet lamp, in a partially darkened room, a vivid purple fluorescence is visible from the edge of the treated film. Under ordinary light, both types of film look exactly the same. A suitable and inexpensive ultraviolet lamp may be purchased from several manufacturers, complete with hood, transformer and filters.
Figure 3 indicates the tell-tale fluorescent reflections from the reel of film. The light rings, which actually glow a purple color, contain the new treated safety film, the dark sections of the reel should contain only nitrate film.
Fluorescent-treated film base is now being used for all 35mm Eastman safety rno
