2 KODAK PROFESSIONAL EKTAR 100 Film • E-4046
Daylight
Use the exposures in the table below for average frontlit
subjects from 2 hours after sunrise to 2 hours before
sunset.
*
Use f/5.6 for backlit close-up subjects.
†
Use f/8 for backlit close-up subjects.
‡
Subject shaded from the sun but lighted by a large area of sky.
Adjustments for Long and Short Exposures
No filter correction or exposure compensation is required
for exposures from 1⁄10,000 second to 1 second. For
critical applications with longer exposure times, make tests
under your conditions.
Electronic Flash
Use the appropriate guide number in the table below as
starting-point recommendations for your equipment.
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 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 tables below as starting points to
expose KODAK PROFESSIONAL EKTAR 100 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.
