2 KODAK HAWKEYE Traffic Surveillance Color Film • TI-2420
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.

BCPS = beam candlepower seconds
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.
