EASTMANColorInternegativeIIFilm5272(35mm)and 7272 (16 mm) is a medium-speed film with excellent image-structure characteristics and color-correction masking. It is intended for making 35 mm or 16 mm internegatives from reversal color originals on EASTMAN EKTACHROME Film 7240™. This film is balanced for printing with tungsten illumination with suitablefiltersinthelightpath.Theinternegativescanthen beprinted onto KODAKColorPrintFilmandEASTMAN EXR Color Print Film.

BASE

This film has a clear acetate safety base with rem-jet backing.

DARKROOM RECOMMENDATIONS

Do not use a safelight. Handle unprocessed film in total darkness.

RECIPROCITY CHARACTERISTICS

You do not need to make any exposure or filter adjustments for exposure times from 1/1000 to 1/10 second. For exposure time of either 1 or 5 seconds, increase exposure by1⁄2 stop and use a KODAK Color Compensating Filter 10Y.

PROCESSING

Most commercial motion-picture laboratories provide a processing service for thisfilm. Pre-packaged kits arealso availablefor preparing the processing solutions. For more information on the EASTMAN ECN-2 Kit Chemicals, check Kodak’s Professional Motion Imaging Price Catalog or see a Kodak sales representative in your country. See KODAK Publication No. H-24, Manual for
ProcessingKODAK Motion PictureFilms,Process ECN-2 Specifications, Module 7, for more information on the
solution formulas and the procedures for continuous machine processing this film.

STORAGE

Store unexposed film at 13˚C (55˚F) or below. Process exposed film promptly. Store processed film at 21˚C
(70˚F) or lower at a relative humidity of 40 to 50 percent for short-term commercial storage; for long-term storage, store it at 2 to 10˚C (35 to 50˚F) at 15- to 30-percent humidity.For more information on long-term storage, see KODAK Publication H-23, The Book of Film Care.

IDENTIFICATION

After processing, the product code numbers 5272 and 7272; emulsion and roll number identification; EASTMAN KEYKODE Numbers; and a film identification code (S) are visible along the length of the film.

LABORATORY AIM DENSITY (LAD) CONTROL METHOD

To maintain optimum quality and consistency in the final prints, the laboratory must carefully control the color timing, printing, and duplicating procedures. Laboratory Aim Density (LAD) Control Film provides a simple, effective, and easily implemented control method for the production of master positives and duplicate negatives from negative originals.
All film in the printing original should be color timed relative to LAD Control Film supplied byEastman Kodak Company. The reversal LAD control film specified may be made on EASTMAN EKTACHROME Film 7240 flashed and processed to Status M densities of Red 1.10, Green 1.10, and Blue 1.10. The LAD Control Film is printed at the center of the printer range, usually TAPE 25-25-25. Printer setup (speed, bulb voltage, TRIM, filtration, etc.) is determined by printing the large gray patch in the LAD Control Film to the specified Laboratory Aim Density values on the duplicating film, chosentobeatthecenteroftheusablestraight-lineportion of the duplicating film’s characteristic curves. The Status M Laboratory Aim Density values for EASTMAN Color Internegative II Film are as follows:
Red Green Blue Tolerance
0.90 1.30 1.70 ± 0.12 density
Formakingprints,theprocessedinternegativemaythen be timed relative to a negative LAD Control Film using densitometry or an electronic color analyzer. On-aim internegatives and duplicate negatives will normally time near TAPE 29-29-29 compared to the negative LAD Control Film printed at TAPE 25-25-25. The LAD on the print film is a neutral gray of 1.0 visual density. The LAD Control Method* assumes that the film and process sensitometry are within specification.

PRINTING CONDITIONS

In all printer setups for printing EASTMAN Color InternegativeIIFilm5272/7272,includea heat absorbing (infrared) filter such as a KODAK Heat Absorbing Glass, No. 2043, and a KODAK WRATTEN Gelatin Filter No. 2B to absorb ultraviolet (UV) light. For high light output with very long bulb life, operate the printer bulb at approximately 80 percent of rated voltage. Use a well-regulated constant-current dc power supply.
Print the LAD Control Film at the center of the printer balance range, usually TAPE 25-25-25 on an additive printer. Print other scenes in the original as determined by color timing relative to the reversal LAD Control Film. Choose the printer speed and filtration to normalize the additive TRIM settings near the center of their range to allow for slight variations in film and printer.
On subtractive printers, choose the filter pack and light control for both the removal and addition of filters for color correction. You can use EASTMAN Lamphouse ModificationFilters in subtractive printers to more closely balance the spectral characteristics of subtractive lamphouses with additive lamphouses so that prints made on a subtractive printermore closely match thosemade on additive printers. On optical printers, set the lens aperture considering sharpness, depth of focus, and light transmittance characteristics. Use ground glass or other diffusers to improve uniformity of illumination. Clean and align optics for optimum light output and uniformity.

IMAGE STRUCTURE

The modulation-transfer curve, rms granularity, and resolving-power data were generated from samples of EASTMANColor NegativeIIFilmexposedwithtungsten light and processed as recommended in Process ECN-2 chemicals.

These photographic modulation-transfer values were determined by using a method similarto theone described in ANSIStandardPH2.39-1977(R1990).Thefilm was exposed with the specified illuminant to spatially varying sinusoidal test patterns having anaerial image modulation of anominal 60 percent at the image plane, with processing as indicated. In most cases, the photographic modulation-transfer values are influenced by development-adjacency effects and are not equivalent to the true optical modulation-transfer curve of the emulsion layer in the particular photographic product.
