TECHNICAL DATA / COLOR REVERSAL FILM
KODAK EKTACHROME 64T
Professional Film
This medium-speed color transparency film features
excellent color reproduction, very fine grain, and very high
sharpness. It is designed for exposure with tungsten
illumination
(3200 K). The film is an excellent choice for photographing
products, room interiors, titles, and artwork. Primary
applications include catalog, furniture, and architectural
photography, and copying.
KODAK EKTACHROME 64T Professional Film has an
intended exposure range of 1/10,000 second to 10 seconds.
Use this film to produce color transparencies for viewing
with 5000 K illumination. You can also use the
transparencies for printing by photomechanical methods and
by photographic methods of direct duplication and direct
reversal printing. In addition, you can scan transparencies for
digital printing and for graphic arts and photo CD
applications.

STORAGE AND HANDLING
Load and unload roll film in subdued light. Load and unload
sheet film in total darkness using light-tight film holders.
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 transparencies from strong light, and store them in
a cool, dry place. For more information, 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
Exposure Index Numbers
Use the exposure index numbers below with cameras or light
meters marked for ISO or ASA speeds or exposure indexes
(EI). 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.

Index
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.
Vary the recommended filtration by at least ±CC10, and
increase or decrease exposure accordingly.
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.

Tungsten Light
For best color rendition, use tungsten photolamps (3200 K)
at their rated voltage. If voltage varies significantly, the color
of the lamp will change. Other light sources may not give
equally good results, even with filters. Unless you want a
special effect, do not mix light sources, particularly tungsten
light and daylight.

*This
is a high-pressure sodium-vapor lamp. The information in the table
may not apply to other manufacturers' high-pressure sodium-vapor
lamps due to differences in spectral characteristics.
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.

Adjustments for Long and Short Exposures
PRINTING TRANSPARENCIES
No filter correction or exposure compensation is normally
required for EKTACHROME 64T Professional Film at
exposure times of 1/10,000 second to 10 seconds. For a
100-second exposure, increase exposure by 1/3 stop and add
a CC05R filter.
For more specific information when using sheet film, see
the product packaging. Exposure index and filter
recommendations for the specific emulsion number are
listed on the box. Included are recommendations at 1/10, 5,
30, and 100 seconds.
You can reproduce images made on EKTACHROME 64T
Professional Film by using a variety of Kodak materials:
PROCESSING
Process EKTACHROME 64T Professional Film in KODAK
Chemicals, Process E-6.
For consistent processing of this and all other
EKTACHROME Films, use a lab that is a member of the
KODAK Q-LAB Process Monitoring Service.

RETOUCHING
Use KODAK E-6 Transparency Retouching Dyes. You can
chemically retouch sheet and 120-size film on both the base
and the emulsion side. Retouch only the emulsion side on the
135 size. For information on retouching equipment, supplies,
and techniques, see KODAK Publication No. E-68,

Film.

SCANNING TRANSPARENCIES
For Graphic Arts Applications
The KODAK EKTACHROME Film family is characterized
by sets of image dyes which perform similarly when
scanned. The scanner operator can set up one basic tone scale
and color-correction channel for all EKTACHROME Films
and then optimize the tone scale and gray balance for the
requirements of individual images.
Use the KODAK Color Input Target / Q-60E1 (4 x 5inch
transparencies) or Q-60E3A (35 mm slide) to establish the
setup for KODAK EKTACHROME Films on all scanners.
This target meets ANSI standards and represents the dye sets
of all EKTACHROME Films.
For Photo CD Applications
Use the Universal E-6 Film Term to scan all KODAK
EKTACHROME films for Photo CD Imaging Workstation
applications.
For Output to a Photo CD Player: Using the Universal E-6
Film Term should result in an image that closely matches
your original transparency in density, tone scale, and overall
color balance when viewed on a player.
For Output to Devices Other than Photo CD Players: The
YCC data that results when using the Universal E-6 Film
Term is capable of producing a high-quality duplicate of
your original transparency in terms of density, tone scale,
and color reproduction. Final quality of your reproduced
image depends on the capabilities of your output device, the
viewing environment, and the rendering path used.
