2 KODAK PROFESSIONAL EKTACHROME Films E100G and E100GX • E-4024
STORAGE AND HANDLING
Load and unload film in subdued light.
Store unexposed film in a refrigerator at 13° C (55° F) or
lower in the original sealed package. To avoid moisture
condensation on film that has been refrigerated, allow the
film to warm up to room temperature before opening the
package. Process film as soon as possible after exposure.
Protect processed film from strong light, and store it in a
cool, dry place. For more information on storing
transparencies, see KODAK Publication No. E-30, Storage
and Care of KODAK Photographic Materials—Before and
After Processing.
DARKROOM RECOMMENDATIONS
Do not use a safelight. Handle unprocessed film in total
darkness.
EXPOSURE
Use the exposure index (EI) numbers below with meters and
cameras 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 light 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.
*
Use f/8 for backlit close-up subjects.

Electronic Flash
Use the appropriate guide number in the table below 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.

BCPS = beam candlepower seconds
Multiple Exposure with Electronic Flash
No filter corrections or exposure adjustments are required
for the effects of multiple, consecutive flashes (multipops)
up to 4 flashes. For 8 flashes, add CC05M filtration.
Adjustments for Long and Short Exposures
No filter correction or exposure compensation is required for
exposure times from 1/10,000 to 10 seconds. At exposure
times of 120 seconds, add CC10R filtration.
Note: This information applies only when the films are
exposed to daylight. The data are based on average
emulsions rounded to the nearest 1/3 stop and assume
normal, recommended processing. Use the data only as a
guide. For critical applications, make tests under your
conditions.
