TECHNICAL DATA /

COLOR NEGATIVE FILM

KODAK HAWKEYE Traffic Surveillance Color Film is a 400
speed color negative film for traffic surveillance
applications. KODAK T-GRAIN emulsion technology
provides extremely fine grain and high sharpness, and wide
exposure latitude allows a range of exposures from 2 stops
under to 3 stops over normal. Other features include:

• Improved color saturation; accurate colors

• Push performance to EI 800

• Optimized for use with film scanners; durable
emulsion overcoat prevents scratches

• Panchromatic sensitivity to 660 nm

• Balanced for daylight or electronic flash, and may also
be used under mixed lighting

• Prints compatibly with KODAK GOLD and MAX
Versatility Films

• Process using KODAK FLEXICOLOR Chemicals,
Process C-41

• Coated on a 0.0048-inch (0.12 mm) acetate base

DARKROOM RECOMMENDATIONS

Handle unprocessed film in total darkness—do not use a
safelight.

Process this film in total darkness through the bleach

step in Process C-41.

STORAGE AND HANDLING

Load and unload film in subdued light.

Store unexposed film at 70° F (21° C) or lower in the
original sealed package. Process film as soon as possible
after exposure. Protect negatives from strong light. For
more information about storing negatives, see KODAK
Publication No. E-30, Storage and Care of KODAK
Photographic Materials—Before and After Processing.

EXPOSURE

Speed:

Use these speed numbers with meters and cameras
marked for ISO, ASA, or DIN speeds or exposure indexes.
For critical work, make a series of test exposures.

Daylight Exposure:

Use the exposures in the table below for average frontlit
subjects from 2 hours after sunrise to 2 hours before
sunset when exposing at EI 400.

Electronic Flash:

Use the guide numbers in the table below as starting-point
recommendations for your equipment. To determine the
lens opening, divide the guide number by the
flash-to-subject distance.

For light sources other than daylight, use the filtration and

Exposure

Adjustment

Fluorescent and High Intensity Discharge Light:

Though this film is tolerant of mixed-lighting situations, for
best color results under uniform fluorescent or
high-intensity discharge sources, use the exposure and
filter recommendations given below. These
recommendations are starting points.

Actual filtration may vary between lamps and lamp
manufacturers. Depending on the specific source,
additional filtration or special printing may be required to
achieve best results.

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 lamps, use exposure times of 1/125
second or longer.

Note: Do not change the film speed setting when metering

for built-in meters) for specific information.

Reciprocity

Compensation for reciprocity failure is not necessary for
exposures of 1/10,000 second to 10 seconds. Exposures
longer than 10 seconds may require exposure
compensation and/or filtration, and should be tested for
the application.
