Description

KODAK EKTACHROME 160T Professional Film is a medium-speed color-transparency film featuring very fine grain and high sharpness. It is designed for exposure with tungsten illumination (3200 K). You can also expose it with photolamps (3400 K), daylight, or electronic flash using filters.

The film is well-suited for photojournalism, theater, fashion, editorial portraiture, architectural interiors, and motion-picture still photography where there is tungsten illumination. It has an intended exposure range of 1/10,000 to 1/10 second with no filter or exposure adjustment.

Use this film to produce color transparencies for projection or viewing with 5000 K illumination. You can also make duplicate transparencies by direct printing. To make color prints, you can print transparencies directly onto color-reversal paper. Or make internegatives for printing onto color-negative paper. You can also scan transparencies for digital printing, and for graphic-arts and Photo CD applications.

Sizes Available

Sizes and catalog numbers may differ from country to country. See your dealer who supplies KODAK PROFESSIONAL Products.

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 the film as soon as possible after exposure.

Protect processed film from strong light, and store them in a cool, dry place. For more information on storing transparencies, see KODAK Publication No. E-30, Storage and Care of KODAK Films and Papers—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 (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.

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 of different color qualities, particularly tungsten light and daylight.

These exposure recommendations are based on two tungsten (3200 K) reflector-type photolamps at 45 degrees from the camera-subject axis. Use one lamp as a fill-in light close to the camera at lens level, the other lamp as the main light 2 to 4 feet higher.

Use these exposure settings as guides. They give a lighting ratio of about 3 to 1. For a 2 to 1 ratio, move the fill-in light to the same distance as the main light and use a 1/2-stop smaller lens opening.

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.

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.

Daylight

Use the exposures in the table below for average front-lit subjects from 2 hours after sunrise to 2 hours before sunset.

Lens opening with a KODAK WRATTEN Gelatin Filter No. 85B.

Electronic Flash

Use a KODAK WRATTEN Gelatin Filter No. 85B, or equivalent. Calculate the guide number based on the film speed for daylight, ISO 100.

Adjustments for Long and Short Exposures

No filter correction or exposure adjustment is normally required for EKTACHROME 160T Professional Film at exposure times from 1/10,000 second to 1/10 second. For a 1 second exposure, increase exposure by 1/3 stop and add a CC10R filter. Longer exposures are not recommended.

Note: This information applies only when the film is exposed to tungsten illumination. The data are based on average emulsions and assume normal, recommended processing. Use the data only as a guide. For critical applications, make tests under your conditions.

Processing

Process EKTACHROME 160T Professional Film in KODAK Chemicals, Process E-6. For best quality, use the normal speed rating of EI 160 and normal processing.

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 the 120 format on both the base side and the emulsion side. Retouch only the emulsion side of 35 mm formats.

For information on retouching equipment, supplies, and techniques, see KODAK Publication E-68, Retouching Color Transparencies on KODAK EKTACHROME Film.

Scanning Transparencies

For Graphic Arts Applications

The KODAK EKTACHROME Film family is characterized by sets of image dyes that 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 5–inch transparency) or Q-60E3 (35 mm slide) to establish the setup for KODAK EKTACHROME Films on all scanners. These targets meet ANSI standards and represent 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 that is used.
