TECHNICAL DATA / COLOR NEGATIVE FILM
KODAK HAWKEYE Traffic
Surveillance Color 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.
Exposure Index (EI)
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.

Filters
For light sources other than daylight, use the filtration and
exposure compensation in the table below.
Note: Do not change the film speed setting when metering
through a filter. Metering through filters may affect light
meter accuracy; see the meter manual (or camera manual
for built-in meters) for specific information.

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.

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.

PROCESSING
Normal Processing:
Use KODAK FLEXICOLOR Chemicals, Process C-41, in any
processing equipment designed to accommodate Process
C-41.
Push Processing:
This film may be “pushed” 1 stop by exposing at EI 800,
and extending the development time in Process C-41. (This
time increase may not be possible in all processing
equipment.)
JUDGING NEGATIVE EXPOSURES
Expose this film properly for best results.
Check the exposure level of the color negative with a
suitable electronic densitometer equipped with a filter
such as the red filter for Status M Densitometry, or a
KODAK WRATTEN Gelatin Filter No. 92. Depending on
the subject and the light source used for exposure, a
normally exposed color negative measured through the
red filter should have the approximate densities listed
below. These densities apply for the recommended light
sources and correct processing of the negative.
Densities of Properly Exposed and Processed
Negatives:
Expose this film properly for optimum results.
Check the exposure level of the color negative with a
suitable electronic densitometer equipped with a filter
such as the red filter for Status M Densitometry, or a
KODAK WRATTEN Gelatin Filter No. 92. Depending on
the subject and the light source used for exposure, a
normally exposed color negative measured through the
red filter should have the approximate densities listed
below. These densities apply for the recommended light
sources and correct processing of the negative.

SCANNING NEGATIVES
General
Traffic Surveillance Color Film negatives can be easily
scanned with a variety of photomultiplier tube (PMT),
linear-array charge-coupled device (CCD) and area-array
CCD scanners. The film can be scanned using desktop as
well as higher-end drum or flat-bed scanners. Since there is
no established standard for filter sets used in film scanners,
each manufacturer’s scanner will have its own
characteristic output. The sensitivity of a scanner to a
film’s dye set is determined by the spectral sensitivity of
the CCD and the spectral distribution of the colored filters
used to capture the red, green and blue information
contained in the film. A scanner’s characteristic output
may also be affected by the look-up tables or matrices used
by the scanner to output information for monitors,
transmission, etc. These tables or matrices can be in the
form of a “plug-in” program used with a specific image
manipulation software package, updateable ROMs
included with the equipment, or fixed algorithms for
determining calibration and balancing, similar to those
used in photographic color printing equipment.
The generic “color negative film” channel designation
available with scanner software will provide only a starting
point for balancing. The final color balancing and
adjustment of scene-dependent contrast and brightness
for any particular image can be done using scanner
controls at the pre-scan stage, or after the image is
imported through the imaging software or workstation.
Some scanners allow for the use of “plug-in” programs
that will calibrate on D-min film stock. Since every color
negative film has a different colored-coupler mask, the
optimum D-min balance will be different for each film.
Therefore, optimum scanning of these films are
accomplished through the use of specifically calibrated
channels.

• This is a new method which replaces rms
granularity. It is on a different scale, which cannot
be compared to rms granularity.
• The scale is a uniform perceptual scale, with a
change of 4 units representing a Just Noticeable
Difference for 90% of observers.
• Index value representing the approximate visual
threshold for graininess: 25.
• Standardized inspection distance for all print sizes:
35.6 cm (14 inches).
• In practice, prints larger than 10.2 x 15.2 cm (4x6
inches) will likely be viewed from distances greater
than 35.6 cm (14 inches), thereby reducing overall
graininess that is perceived.
• These Grain Index numbers may not represent
graininess observed from more specular printing
illuminants, such as condenser enlargers.
