Description

This fast color transparency film is specifically balanced for exposure with tungsten illumination. It is ideal for motion picture and television stills, fashion, glamour, editorial, and theatre/concert under existing tungsten light. Its high speed makes it an excellent choice for indoor action photography, or for situations that require small apertures for good depth of field.

This film features bold, saturated colors and uses KODAK T-GRAIN Emulsions for fine grain and high sharpness. It has an intended exposure range of 1/10,000 to 1/10 second with no filter or exposure adjustment. You can use exposure times up to 10 seconds with an exposure increase and a color compensating filter.

Use this film to produce color transparencies for projection or viewing with 5000 K illumination.

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 films at 13°C (55°F) or lower in the original sealed package. To avoid moisture condensation on the film that has been refrigerated, allow the film to warm up to room temperature before opening the package.

Store exposed film in a cool, dry place. 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 about 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

Speed and Filter

Use the Exposure Index (EI) numbers below with meters and cameras marked for ISO, DIN, or ASA speed, 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.

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.

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.

Electronic Flash

Use a KODAK WRATTEN Gelatin Filter No. 85B, or equivalent. Calculate the guide number based on the film speed for daylight, ISO 200.

Adjustments for Long and Short Exposures

No filter correction or exposure compensation is required for 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 CC05R filter. For an exposure of 10 seconds, increase exposure by 1/2 stop and use a CC10R filter. Longer exposures may result in color balance or contrast mismatches, and are not recommended.

Note: This information applies only when the film is exposed to tungsten illumination. 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.

Processing

Process EKTACHROME 320T 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. 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.

Printing Transparencies

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 5-inch 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.
