TECHNICAL DATA /
COLOR REVERSAL FILM
KODAK EKTACHROME 64T Color
Reversal Film 7280
KODAK EKTACHROME 64T Color Reversal Film 7280 is
a 64-speed color reversal motion picture camera film
designed for exposure with tungsten illumination (3200 K).
This film offers excellent color reproduction, fine grain, and
high sharpness. 7280 has outstanding reciprocity
characteristics, which give consistent color balance and
speed over a wide range of exposures. EKTACHROME 64T
Film should be processed in an E-6 Process.
BASE
KODAK EKTACHROME 64T Color Reversal Film 7280
has an acetate safety base.
DARKROOM RECOMMENDATIONS
Do not use a safelight. Handle unprocessed film in total
darkness.
STORAGE
Store unexposed film at 13°C (55°F) or lower. For extended
storage, store at -18°C (0°F) or lower. Process exposed film
promptly. Store processed film according to the
recommendations in ANSI/PIMA IT9.11-1998: for
medium-term storage (minimum of ten years), store at 10°C
(50°F) or lower at a relative humidity of 20 to 30 percent; for
extended-term storage (for preservation of material having
permanent value), store at 2°C (35°F) or lower at a relative
humidity of 20 to 30 percent. For active use, store at 25°C
(77°F) or lower, at a relative humidity of 50 +/- 5 percent.
This relates to optimized film handling rather than
preservation; static, dust-attraction and curl-related
problems are generally minimized at the higher relative
humidity. After usage, the film should be returned to the
appropriate medium- or long-term storage conditions as
soon as possible.
For more information about medium- and long-term
storage, see ANSI/PIMA IT9.11-1998, SMPTE
RP131-2002, and KODAK Publications No. H-1, KODAK

EXPOSURE INDEXES
Tungsten (3200 K) - 64 / Daylight (5500 K) - 40
1
Use these indexes with incident- or reflected-light
exposure meters and cameras marked for ISO or ASA speeds
or exposure indexes. These indexes apply for meter readings
of average subjects made from the camera position or for
readings made from a gray card of 18-percent reflectance
held close to and in front of the subject. For unusually light-
or dark-colored subjects, decrease or increase the exposure
indicated by the meter accordingly.
COLOR BALANCE
These films are balanced for exposure with tungsten
illumination (3200 K). For other light sources, use the
correction filters in the table below.
1
These are approximate corrections only. Some light sources are
extremely variable. For critical applications, light source color
temperature should be verified and test exposures should be performed.
Note: Consult the manufacturer of high-intensity ultraviolet
lamps for safety information on ultraviolet radiation and
ozone generation.
