Negative Film 5231/ 7231™  
DESCRIPTION  
EXPOSURE INDEX/DIN  
The speed and grain characteristics of EASTMAN PLUS-X  
Negative Film 5231 (35 mm) and 7231 (16 mm) make it  
well-suited for general motion picture production—both  
outdoors and in the studio. These film characteristics provide  
an excellent balance between the maximum desirable speed  
for general production work and a fine-grain negative for  
that speed. The speed of this panchromatic film permits the  
use of small apertures, thus allowing good depth of field. The  
film is also widely used for making composite projection  
background scenes.  
(For development to a gamma of 0.65 to 0.70.)  
Daylight—80/20  
Tungsten (3200 K)—64/19  
Use these indexes with incident- or reflected-light exposure  
meters and cameras marked for ISO or ASA speeds or  
exposure indexes. These indexes apply for meter readings of  
average subjects made from the camera position or for  
readings made from a gray card of 18-percent reflectance  
held close to and in front of the subject. For unusually light-  
or dark-colored subjects, decrease or increase the exposure  
indicated by the meter accordingly.

Handle unprocessed film in total darkness. If necessary, you  
can use a safelight for a few seconds only after developing is  
50 percent complete. Use a safelight equipped with a 15-watt  
bulb and a KODAK Safelight Filter No. 3 / dark green. Keep  
the safelight at least 4 feet (1.2 metres) from the film.

Filter No.  
Store unexposed film at 13˚C (55˚F) or lower. Process  
exposed film promptly. Store processed film at 21˚C (70˚F)  
or lower at a relative humidity of 40 to 50 percent for normal  
commercial storage. For more information on long-term  
storage, see KODAK Publications No. H-1, KODAK Motion  
Picture Film, and No. H-23, The Book of Film Care.

* For use in bright sunlight to reduce the exposure without modifying color  
rendering or depth of field. This neutral density filter No. 96 with a density of  
0.9 reduces the exposure.  
RECIPROCITY  
You do not need to make any filter corrections or exposure  
adjustments for exposure times from 1/10,000 to 1/10  
second. At an exposure time of 1 second, increase exposure  
by 12 stop.

These photographic modulation-transfer values were  
determined by using a method similar to the one described in  
ANSI Standard PH2.39-1977(R1990). The film was  
exposed with the specified illuminant to spatially varying  
sinusoidal test patterns having an aerial image modulation of  
a nominal 60 percent at the image plane, with processing as  
indicated. In most cases, these photographic

modulation-transfer values are influenced by

in the particular photographic product.
