PRO IMAGE 100 Color Negative Film
DESCRIPTION
KODAK PROFESSIONAL PRO IMAGE 100 Color
Negative Film is a medium speed (EI 100) film that features
high color saturation, accurate color and pleasing skin-tone
reproduction, and good underexposure latitude. It is intended
for portrait and social applications, and can be stored at room
temperature—even in hot, humid climates. Its printing
characteristics are similar to those of KODAK GOLD Films
to help simplify printing for photofinishers.
DARKROOM RECOMMENDATIONS
Do not use a safelight. Handle unprocessed film in total
darkness.
STORAGE AND HANDLING
Load and unload your camera in subdued light.
Store unexposed film at room temperature. For best
results, store film at 21°C (70°F) or lower, and process film
as soon as possible after exposure.
Protect negatives from strong light, and store them in a
cool, dry place. For more information about storing
negatives, see KODAK Publication No. E-30, Storage and
Care of KODAK Photographic Materials—Before and After
Processing.

EXPOSURE
Exposure Compensation
Use the filter recommendations and exposure adjustments in
the table below under uniform lighting.
Daylight
Use the exposures in the table below for average frontlit
subjects from two hours after sunrise to two hours before
sunset.

Electronic Flash
Use the guide number in the following table as a starting
point for your equipment. Select the unit output closest to the
number given by your flash manufacturer, then find the
guide number for metres or feet.
To determine the lens opening, divide the guide number
by the flash-to-subject distance. If negatives are consistently
too dense (overexposed), use a higher guide number; if they
are too thin (underexposed), use a lower number.
Fluorescent and High-Intensity Discharge
Lamps
Use the color-compensating filters and exposure adjustments
in the following tables as starting points to expose this film
under fluorescent or high-intensity discharge lamps. For
critical applications, make a series of test exposures under
your actual conditions.
To avoid the brightness and color variations that occur
during a single alternating-current cycle, use exposure
times of 1/60 second or longer with fluorescent lamps; with
high-intensity discharge lamps, use exposure times of
1/125 second or longer.

Note: When you dont know the type of fluorescent lamps,
try a 10C + 20M filter combination and increase exposure by

stop; color rendition will probably be less than optimum.
Note: Some primary color filters were used in the previous
tables to reduce the number of filters and/or to keep the
exposure adjustment to a minimum. Red filters were
substituted for equivalent filtration in magenta and yellow.
Blue filters were substituted for equivalent filtration in cyan
and magenta.
Adjustments for Long and Short Exposures
No filter corrections or exposure compensation is required
for exposures from 1/10,000 second to 10 seconds.
PROCESSING
Process this film in KODAK FLEXICOLOR Chemicals for
Process C-41.
JUDGING NEGATIVE EXPOSURE
You can check the exposure level with a suitable electronic
densitometer equipped with a filter such as a KODAK
WRATTEN Gelatin Filter No. 92 or the red filter for
Status M densitometry. Depending on the subject and the
light source used for exposure, a normally exposed and
processed color negative measured through the red filter
should have the approximate densities listed below.
Because of the extreme range in skin color, use these red
density values for a normally lighted forehead only as a
guide. For best results, use a KODAK Gray Card (gray side).
