U s e : The speed and grain characteristics of EASTMAN
PLUS-X Negative Film make it well suited for general
motion picture production. These film characteristics
p rovide an excellent balance between the maximum desir-
able speed for general production work and the fine grain.
General Pro p e r t i e s : The medium speed of EASTMAN
PLUS-X Negative Film 5231 and 7231 permits the use
of relatively small apertures in daylight (thus allowing good
depth of field). The film is widely used for making
composite projection background scenes.
