2 KODAK PROFESSIONAL EKTACHROME Film E200 • E-28
EXPOSURE
Use the exposure index (EI) numbers below with cameras or
light meters marked for ISO or ASA speeds or exposure
indexes. Do not change the film-speed setting when metering
through a filter. Metering through filters may affect meter
accuracy; see your meter or camera manual for specific
information. For critical work, make a series of test
exposures.
Daylight
Use the exposures in the table below for average frontlit
subjects from 2 hours after sunrise to 2 hours before sunset.
Electronic Flash
Use the appropriate guide number in the following table as a
starting point for your equipment. First select the unit output
closest to the number given by your flash manufacturer. Then
find the guide number for feet or metres. To determine the
lens opening, divide the guide number by the flash-to-subject
distance. If transparencies are consistently too thin
(overexposed), use a higher guide number; if they are too
dense (underexposed), use a lower number.

Fluorescent and High-Intensity Discharge
Lamps
Use the color-compensating filters and exposure adjustments
below 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 1/125 second or longer.
Note: Consult the manufacturer of high-intensity lamps for
ozone ventilation requirements and safety information on
ultraviolet radiation.
Some primary color filters were used in the previous tables
to reduce the number of filters and 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.
